The specialty chemicals manufacturer supports users with sound expertise and innovative materials. Interview with Dr. Anja Laqua, ESHA & Regulatory Affairs.
Sustainability, product safety and environmental protection are important goals in industry. Numerous laws and guidelines are designed to protect consumers, employees and the environment. These requirements can vary greatly from country to country. This poses a challenge for companies, especially in product development, because in order to bring a new product to market, it must meet the local requirements of all markets in which it is sold. Kuraray, one of the world's leading specialty chemicals manufacturers, supports users of PVB materials of its Mowital brand, for example, with well-founded information and expertise. In an interview on the ESHA (Environment, Safety, & Health Affairs) focus of specialty chemicals manufacturers, Dr. Anja Laqua, ESHA & Regulatory Affairs at Kuraray discusses why there must be a rethink on sustainability and how customers benefit from working with Kuraray when the environment and product safety are concerned.

 

Dr. Laqua, sustainability is increasingly becoming a core issue for industry. What challenges do you see in this regard?

Dr. Anja Laqua: Awareness of sustainability and health has increased enormously in recent years. Consumers are right to demand that the products they buy are sustainable and environmentally friendly. Many industrial companies are working to develop products that meet these requirements. An integral, sustainable approach, however, requires another important point.

Which one is that?

Dr. Anja Laqua: Dialogue! Environmental and occupational safety issues often cannot be solved within a single company. There is a need for an exchange of ideas between suppliers, customers and politicians - for example on the use of different plastics for certain applications or on waste and disposal and, of course, on the legal framework conditions. At Kuraray, we are constantly working to promote and stimulate this dialogue.

How do we do that?

Dr. Anja Laqua: Above all, we offer users of our plastic materials technical know-how on compliance issues, from basics such as good manufacturing practice (GMP) regulations to the EU chemicals regulation REACH. Many of our customers also have very specific questions about their applications. The PVB materials of our Mowital brand are used, for example, in printing inks for food packaging. Depending on the market in which the packaged products are sold, there are very different regulations and requirements - such as the Swiss Printing Ink Ordinance or corresponding specifications in the EU and the USA. Of course, it is always important to keep up to date, because the legal situation changes regularly.

This sounds very complex. How do you help your customers meet these requirements?

Dr. Anja Laqua: The ESHA & Regulatory Affairs team at Kuraray brings together experts from a variety of disciplines, including environment, health and product safety. Our specialists compile information for users of Mowital in the form of statements, certificates and regulatory brochures. This provides customers with answers to almost all compliance-relevant questions, which is unique on the market.

To what extent is this service special?

Dr. Anja Laqua: I have to explain this briefly. For Kuraray, as one of the world's leading specialty chemicals manufacturers, it is particularly important that our customers can rely on our statements. The answers to compliance-relevant questions that users receive are therefore well thought out and very precisely checked and weighed, both in terms of content and technical aspects. This is based on extensive research, which of course takes a lot of work and time. Only a few manufacturers offer this in this form, but this is the only way we can give our customers reliable information.

With the information you provide the basis for customers to develop new products, among other things.

Dr. Anja Laqua: Exactly! In the Mowital sector, 3D printing is currently a trend topic, for which we are, for example, examining the corresponding possible applications for interested parties who produce 3D printing filaments. It can also happen that we advise a customer against using our material for an application because we come to the conclusion that our material does not cover all legal requirements for the application.

What would be an example?

Dr. Anja Laqua: Our PVB materials have specific properties with which they could bring advantages for certain applications in the pharmaceutical industry. However, the plastic is not positively listed in this area. In such cases, unfortunately, we have to say: Good idea, but legally this is not possible with our material. On the market this is not always formulated as clearly as with Kuraray. For us, security, whether legal or physical, always takes precedence. Our customers can rely on this.

In addition to applications for customers, Kuraray also works on many topics in the field of ESHA ...

Dr. Anja Laqua: That's right! Kuraray is especially concerned about the safety of its own employees. The topic is firmly anchored in our corporate culture and is lived and promoted in the KURASAFE safety program of Kuraray Europe GmbH and other such programs. We are also constantly working to optimize our processes and, for example, to reduce our CO2 emissions and avoid waste. At Kuraray, three teams around the world deal with very different sustainability issues. For example, one aim is to promote the development of new environmentally friendly products.

Such as biopolymer plantic, which is mainly made from corn starch?

Dr. Anja Laqua: Exactly. Another example is the bioelastomer Septon Bio, a TPE raw material made from sugar cane-based organic farnesene. Our colleagues in research and development are constantly working on new product solutions. Sustainable materials that are biodegradable, compostable or recyclable are becoming increasingly important. In the area of ESHA & Regulatory Affairs, we provide the legal information with which our customers can use the innovative materials in their applications.

How will ESHA change in the coming years?

Dr. Anja Laqua: It is becoming apparent that the requirements that legislators place on chemical substances and materials will continue to increase in the future. This is an important reaction to issues that are currently being discussed extensively in society.

For example, avoiding plastic packaging?

Dr. Anja Laqua: Yes. Or issues such as the CO2 footprint of products and the reduction of microplastics in the environment. At Kuraray, we are well prepared for this because, with our high level of development expertise, we provide appropriate materials and actively assist users in developing products that meet the higher requirements. At the same time, in the future we will focus even more on how we can inform our customers in a comprehensible way and how we can help them for example to meet stricter emissions limits. Our customers can also rely on our know-how in the future.

Thank you very much for the interview!

news-284 Thu, 13 Jun 2019 10:31:39 +0200 Combined expertise for tomorrow's coatings, colorants and adhesives https://www.mowital.com/newsroom/detail-view/news/combined-expertise-for-tomorrows-coatings-colorants-and-adhesives/?tx_news_pi1%5Bcontroller%5D=News&tx_news_pi1%5Baction%5D=detail&cHash=a085c1bcfb675a97261e1df65dceab81 Round-table interview of Kuraray experts: “We're creating tomorrow's industrial materials”
Industrial coatings, colorants and adhesives are constantly expected to do more, yet be simple and cheap to apply. Experts at Kuraray, one of the world's leading speciality chemicals producers, are therefore developing high-performance polymers to make industrial processes more efficient. Innovative materials based on polyvinyl butyral (PVB), polyvinyl alcohol (PVA) and elastomers are better for the environment and can be used in demanding applications from 3D printing to automotive engineering.

In this interview, Dr. Maria Martinez Velencoso, Application Development Engineer for elastomers, Jörg Bruss, Director Global Business for Technical PVB, and Heiko Mack, Head of Poval Business, talk about the demands made on tomorrow's coatings, colorants and adhesives.


Kuraray markets a wide range of materials for the coatings, colorants and adhesives industry. What are the latest trends in this market?

Jörg Bruss: Industry wants durable, high-performance products that can be processed efficiently. At the same time, their impact on health and the environment needs to be minimal. In terms of efficiency we see ourselves as one of the leading producers of speciality chemicals where properties such as viscosity are very important.

Where can viscosity improve efficiency?

Jörg Bruss: In curtain coating, for example. This is an industrial process where parts such as automotive components are coated by passing them through a liquid “curtain” of the coating material. Our new PVB product Mowital® BA 55 HH can be used as a binder in this process. Its specific rheological properties give paints and coatings very uniform flow properties in this process.

So application can be controlled more accurately …

Jörg Bruss: Precisely. The coating can be applied more sparingly and the process can be speeded up, which increases capacity. That even applies for complex processes with several consecutive curtain coating steps. And our product can do even more: it has very good heat resistance and its glass transition temperature (Tg) is 40 percent higher than comparable commercially available PVB grades. BA 55 HH is therefore ideal for applications where materials are heated to up to 200 °C within a short time, for example, heat-seal lacquers and hot-melt adhesives for food packaging.

Heiko Mack: Curtain coating is also used to coat packaging paper. For this application, we offer our new high-molecular-weight KURARAY POVAL™ polyvinyl alcohol KP 200-88 KX. This PVA grade improves rheology in this process and at the same time reduces the amount of material required.

Dr. Maria Martinez Velencoso: The automotive industry is another example. Here, elastomer adhesives are increasingly replacing spot welding. Viscosity is an important requirement here. On today's modern assembly lines, the adhesives are applied by robots. To ensure that they can be pumped through the robotic arms, they need special rheological properties, in other words, special flow properties, and very low viscosity. Using solid rubber has limitations ….

… so Kuraray Liquid Rubber is used?

Dr. Maria Martinez Velencoso: Yes. Our range includes Liquid Rubber grades with different molecular weights — ranging from low to very high — for different applications. They give the adhesives used in the automotive industry the very good flow properties required for processing and also improve their mechanical properties.

Can you explain how?

Dr. Maria Martinez Velencoso: One of the main reasons for using elastomer-based adhesives is their high elasticity. Cars, especially electric cars, are expected to be increasingly lightweight. And because electric engines are quiet, it's becoming more and more important to avoid disturbing noise and vibrations inside and outside the car. To reduce weight, manufacturers are using completely new material combinations for the bodywork. That means, for example, that aluminium and steel may be used right next to each other.

Jörg Bruss: However, they have very different thermal expansion properties when exposed to fluctuations in temperature.

Dr. Maria Martinez Velencoso: Exactly. Aluminium and steel expand and shrink very differently when the temperature changes. So using them together in the car body is a big challenge for adhesive bonding. Adhesives and sealants have to be elastic enough to compensate for differences, noises and vibrations, and give the car body reliable structural stability.

And Liquid Rubber does all that?

Dr. Maria Martinez Velencoso: Indeed! And unlike conventional elastomers, Liquid Rubber remains flexible at very low temperatures. Adhesive compounds with liquid rubber retain their shock resistance even at low temperatures. That ensures safe structures. Tire manufacturers also use this property: Liquid Rubber improves the grip of winter tires. In addition, we are currently developing new products with a low molecular weight. They have a variety of functional groups with which they can be optimally combined with other materials - such as fibers or metals of the car body.

Heiko Mack: Increased health and environmental awareness are other important issues in the coatings, colorants and adhesives sector. Consumers are paying more and more attention to the environmental profile of the products they buy. At Kuraray we’ve been working on that for a long time. We market materials that our industrial customers can use to develop sustainable and healthy solutions with a better environmental profile. Examples are materials with a low VOC content such as the new KURARAY POVAL™ polyvinyl alcohol (PVA) LV grades.

Why is a low VOC content important?

Dr. Maria Martinez Velencoso: Volatile organic compounds (VOCs) can have negative health and environmental effects. In our development labs, we are therefore working to reduce the VOC content of materials, for example, the residual monomer content or the proportion of methanol in PVA.

What’s special about the new KURARAY POVAL™ LV grades?

Heiko Mack: The methanol content of the LV grades is just 0.3 percent — ten times lower than in conventional PVA. That's achieved by a complex purification process that has been specially developed by Kuraray.

So what are KURARAY POVAL™ LV grades used for?

Heiko Mack: At the moment they are used, for example, in cosmetics. We’ve also registered some interest from adhesives manufacturers, especially for consumer adhesives.

Jörg Bruss: Environmentally friendly and healthy product solutions are something the food packaging industry has been talking about for a long time. So far, this sector has mainly used PVC-based colorant systems, but they can cause allergies as a result of their residual monomer content. Major food and beverage producers have therefore announced that they don’t want to use PVC in the future.

What alternatives are there to PVC for printing packaging?

Jörg Bruss: PVB products such as Mowital® from Kuraray have an advantage here. They don’t contain any impurities that cause health problems and are therefore quite safe for consumers. And there's another benefit: although a solvent is used in PVB printing inks, it is normally ethanol, which is biodegradable. Ethanol allows environmentally friendly recycling and it can also be produced sustainably from renewable raw materials.

Heiko Mack: Talking about recycling: the European Commission has set a target for all plastic packaging used in the EU to be reusable or recyclable by 2030. Therefore, we are seeing rising demand for packaging paper, especially from food producers. One challenge for packaging producers is to give paper an effective barrier to oil, grease and oxygen …

… so the packaged food stays fresh and edible for longer and the packaging is stable?

Heiko Mack: Exactly. Our PVA barrier coating product EXCEVAL™ makes packaging impermeable to grease and oil and acts as an effective gas barrier. EXCEVAL™ is an aqueous solution that is used to coat packaging materials. It is also free of chlorine and solvents.

Does it make packaging environment-friendly?

Heiko Mack: Yes. Unlike coatings based, for example, on acrylic latex, EXCEVAL™ is completely biodegradable in water. Together with paper and other biodegradable materials, it can therefore be used to create easily recyclable, environment-friendly alternatives to conventional food packaging.

Can you give a recent example?

Heiko Mack: A big retailer in Germany recently introduced biodegradable coffee capsules. EXCEVAL™ is used as the coating material. That's a completely new application where we are working closely with our colleagues at Eval, Kuraray’s Ethylene Vinyl Alcohol (EVOH) business unit. Eval™ EVOH has been used for a long time in conventional coffee capsules. Thanks to our expertise in many areas, we have developed a high-performance solution for our customers.

Jörg Bruss: 3D printing is another example. In the PVB business, we're currently working on new formulations for printing filaments, which could be used on 3D printers to produce components in injection moulding quality. PVB materials such as Mowital® have an edge over the polylactide (PLA) and acrylonitrile butadiene styrene (ABS) copolymer-based materials that currently dominate this market. They have high mechanical stability so they can be used to produce higher quality surfaces. The experience of our colleagues from Poval is helping us here.

Heiko Mack: Poval has had a 3D printing material in its range for some time: the water-soluble support filament MOWIFLEX™ 3D 2000. Incidentally, this product is now available via the Amazon Business platform. Joint tests with Mowital® show that very good printing results are achieved with our PVA and PVB-based materials.

Dr. Maria Martinez Velencoso: There are an increasing number of applications for elastomers in 3D printing. We offer extra functional types that give the workpieces long-term elasticity.

Heiko Mack: I’m sure there are other areas where we could work together. Our expertise in various materials enables us to create innovative materials for colorants, coatings and adhesives – right up to additive manufacturing.


Many thanks for the interview.

Interview with Dr. Florian Mummy, Research and Development Laboratory Manager at Kuraray
Hattersheim/Frankfurt am Main, March 2019. PVB printing filaments such as those based on Mowital® offer significant advantages for 3D printing compared to PLA and ABS filaments – now and in the future. Dr. Florian Mummy is the research and development laboratory manager at Kuraray, one of the world’s leading manufacturers of specialty chemicals. In the following interview, he explains how PVB-based filaments considerably improve processes and quality in 3D printing. Thanks to their unique properties, these filaments form the basis for future manufacturing methods, while simultaneously preserving the environment.

Dr. Mummy, what developments do you expect for the future in terms of 3D printing?
Dr. Florian Mummy: We’re currently in the second of three evolution phases. In the past, 3D printing was favored for use in development for the rapid manufacture of prototypes. Today, companies are already producing high-volume individual functional components for end use with 3D printers. In the future, additive manufacturing will become an Industry 4.0 standard. Customized products printed on an industrial scale using 3D printers will then become part of everyday life. But that is still quite a way off.

Surely there are still a few challenges that need to be overcome?
Mummy: Yes, because a move to mass production primarily involves improving the quality and reproducibility of 3D printing. The goal is to achieve the same level of quality we’re used to in injection molding. One of the problems here is that it is difficult to predict the mechanical capability of the printed parts. The reason for this is that the printing material (filament) is applied layer by layer due to the technology involved. If there are problems with adhesion between individual layers this leads to failure of the component. This is a well-known issue with the frequently used printing filaments based on polylactic acid (PLA) or acrylonitrile butadiene styrene copolymer (ABS). Printing materials that are partially or entirely made of polyvinyl butyral (PVB), like Mowital, have an advantage in this regard.

What are the benefits of Mowital® for 3D printing?
Mummy: Printing filaments based on Mowital® make it possible to produce 3D-printed objects that can be subjected to higher mechanical loads. The material allows for higher rigidity and break strength in particular. Mowital® has excellent binding power – a key requisite for permanent adhesion of the individual printed layers. Another benefit of the material is that it does not present any health risk. Printing with Mowital®-based printing filaments generates practically no emissions and unpleasant odors. Plus, it is possible to produce top-quality surfaces with PVB printing filaments.  

How exactly does it work?
Mummy: The surfaces of 3D printed objects are initially rough because of the many layers. To achieve a smooth surface they undergo a special type of polishing process, where the surfaces of the 3D prints are sprayed with an aerosol made up of micro-sized alcohol droplets. The individual layers fuse together and at the same time the object solidifies, with any unevenness on the surface being levelled out. This results in a surface that is visually extremely appealing, smooth, and shiny. In contrast to conventional PLA and ABS filaments, Mowital®-based printing filaments allow for the use of aerosol with ethanol, which is harmless to the environment and health. In the case of pure PLA filaments, it is not even possible to achieve smooth surfaces through polishing. And unlike acetone, which has a narcotic effect, and is used in ABS filaments, ethanol enables far more accurate control of the polishing process, and thereby superior quality.

Smooth surfaces for trendy designer products?
Mummy:
Precisely, and there are other applications besides: high-quality packaging for cosmetic products, for instance. The uniquely low yellowness index of the material is also an advantage here. It means that accurate and high-grade coloring of the printing filaments is possible – for a perfect design. Many technical applications also require extremely smooth and exact surfaces to ensure the best possible fit of components, for example. Mowital® could in future help solve challenges in aerospace technology, machine engineering, and semiconductor technology.

Mowital® is compatible with many polymers. Where does this benefit come in with 3D printing?
Mummy: The compatibility of polymers used in printing filaments is decisive when it comes to the level of adhesion in objects that are made from different materials. Mowital® is compatible with a wide variety of polymers. As a result, completely new material combinations are possible. In our research and development department at our Kuraray site at the Hoechst Industrial Park, we have our own 3D printing laboratory, where we further develop and test filaments based on PVA and PVB, together with our POVAL colleagues. The tests have shown, for example, that PVB printing filaments achieve outstanding results in combination with MowiflexTM 3D 2000.

So, with the support filament from Kuraray, based on PVA…
Mummy: Yes, we’ve been supplying our own 3D printing filament for a while now, with MowiflexTM 3D 2000. This PVA-based material makes it possible to print support structures for complex, filigree, and overhanging objects. The distinguishing feature of MowiflexTM 3D 2000 is that it is water-soluble and can easily be washed off with water after printing, without any traces remaining at the contact points. PVA is also the raw material from which Mowital® is derived.

Hence the good compatibility?
Mummy: Exactly. Printing filaments based on Mowital®, like PolySmoothTM from filament manufacturer Polymaker for example, and our own filament MowiflexTM 3D 2000 bond extremely well. In this combination, the materials can achieve their full potential and provide outstanding print quality. For instance, there are no imperfections because of support material that does not adhere sufficiently to the printing filament.

PVB-based printing filaments are still niche products. Will this change?
Mummy: I’m sure of it. I expect PVB materials to grow substantially in importance in 3D printing in the future. The advantages of printing filaments based on Mowital®, for example, are huge. The material enables higher quality while at the same time making for a safer and simpler manufacturing technique. Thanks to the excellent material properties, we’re creating 3D printing solutions of tomorrow.

3D printing filaments: From water solubility to high performance
Thanks to their excellent chemical and mechanical properties, PVB materials Mowital® and PVA resins MowiflexTM are the solution for the challenges currently faced in 3D printing. As a high-performance printing filament and water-soluble support material, they offer new opportunities for 3D printing right up to industrial production:

Mowital® – for smooth surfaces and high mechanical performance

  • Kuraray’s polyvinyl butyrals Mowital® have outstanding adhesive properties. Mowital®-based printing filaments make it possible to manufacture functional parts that can be subjected to high mechanical loads – with excellent break strength and rigidity
  • Mowital® also enables producing top-quality, smooth surfaces for design objects or technical applications in aerospace industries, for example
  • Mowital® is compatible with numerous solvents. Ethanol, which does not pose a threat to human health, can be used as solvent for surface finishing of 3D prints by means of polishing
  • Mowital® is also free from contamination. Printing with Mowital®-based filaments causes only minimal emissions and unpleasant odors
  • Printing filaments based on Mowital, like PolySmoothTM from filament manufacturer Polymaker, are highly compatible with water-soluble support filament MowiflexTM 3D 2000 from Kuraray – for optimal printing results

Mowiflex 3D 2000 – soluble in water for complex structures

  • MowiflexTM 3D 2000 is Kuraray’s own 3D printing filament based on PVA
  • The water-soluble polymer blend enables printing of support structures for complex, filigree, overhanging, or moving parts
  • After printing, support structures made from this material can easily be washed off with water, without any contact traces remaining on the printed object
  • Another advantage is that the dissolved material is biodegradable and can simply be disposed of through waste water

 


“Printing filaments based on PVB materials, such as Mowital®, provide the basis for promoting the development of 3D printing as an industrial production standard,” emphasizes Dr. Florian Mummy, Research and Development Laboratory Manager at specialist chemicals manufacturer Kuraray. “Thanks to their excellent adhesive properties, the materials enable high-performance components to be produced, for instance for machinery.”

news-276 Thu, 14 Feb 2019 14:09:40 +0100 New PVB material for high temperatures with optimized rheology https://www.mowital.com/newsroom/detail-view/news/new-pvb-material-for-high-temperatures-with-optimized-rheology/?tx_news_pi1%5Bcontroller%5D=News&tx_news_pi1%5Baction%5D=detail&cHash=bb6d91ab699456ded4f2491eeb90dfd7 New Mowital® for high temperatures with optimized rheology
At the European Coatings Show from March 19-21, 2019, in Nuremberg, Kuraray will present a new material based on Mowital® polyvinyl butyrals (PVB). Polyvinyl acetal BA 55 HH features a unique rheology and viscosity, which gives coatings and paints very smooth flow properties, ensuring higher quality and minimized material use for industrial coating processes, such as curtain coating.

Temperature-resistant – for stoving enamels and heat-sealable lacquers
BA 55 HH features an up to 40 percent higher glass transition temperature (Tg) compared with similar materials on the market. This makes the PVB material perfect for applications with high processing temperatures starting at 200 degrees Celsius – for example as a binding agent for stoving enamels and heat-sealable lacquers or thermoplastic glues.

With BA 55 HH, Kuraray is expanding its unique portfolio. Under the Mowital® brand, the specialized chemical manufacturer offers PVB materials with technical and chemical properties that are ideally tailored to a wide range of applications, from printing inks to adhesive systems.

news-270 Mon, 12 Nov 2018 14:57:36 +0100 Going green is coming into fashion PVB as an opportunity in packaging printing https://www.mowital.com/newsroom/detail-view/news/going-green-is-coming-into-fashion-pvb-as-an-opportunity-in-packaging-printing/?tx_news_pi1%5Bcontroller%5D=News&tx_news_pi1%5Baction%5D=detail&cHash=844003483dd6aae69184b28bac99f03a Environmentally-friendly PVB inks are harmless for food packagings, and their importance in packaging printing is increasing worldwide
The market for packaging printing is growing worldwide and with it the demands placed on packaging inks. The future belongs to environmentally-friendly PVB ink systems, because they are harmless in food packagings and deliver brilliant results precisely where other printing systems reach their limits. At the same time, PVB inks offer additional advantages.

According to a recent study by the VDMA (Verband Deutscher Maschinen- und Anlagenbau - Mechanical Engineering Industry Association), global turnover for packaging printing is rising by more than five percent annually. At the same time, the demands placed on printing inks by consumers, industry and legislators are growing. We at Kuraray, as one of the world's leading specialty chemicals manufacturers and suppliers to the printing ink industry, are observing two important trends: The increasing awareness of environmentally-friendly and harmless inks, and a growing demand for individually-adapted special inks. Polyvinyl butyral (PVB) ink systems, such as those based on our PVB resin Mowital®, offer advantages for both trends.

Harmless inks for food packaging
When printing food packagings, consumer protection groups are repeatedly demanding that polyvinyl chloride-(PVC)-based inks be avoided. This is because their possible contamination with residual monomers means that they could trigger allergies. Many food companies and discounters are therefore already setting themselves high standards for the packaging of their products. After Switzerland, we now expect the German Printing Ink Ordinance to place higher demands on food packagings in the European economic area. As a result, PVB inks are set to increase in importance. They are free of harmful impurities and therefore absolutely harmless to the consumer.

Good compatibility with other ink components is one of the reasons why food-packaging printing is already one of the most important application areas for PVB ink today. With its outstanding properties, it enables durable prints for demanding packaging applications. Modified PVB printing inks are resistant to heat and steam treatments, e.g. for sterilisation packagings. In microwave ovens, PVB inks do not release any harmful emissions and are completely safe for ready-meal packagings. PVB inks are also advantageous for deep-freeze packagings. Unlike nitrocellulose (NC) inks, for example, they remain softer and more flexible at very low temperatures – without the addition of plasticizers. At the same time, they meet the high standards for pet food packagings.

Brilliance and colour strength for complex packaging designs
PVB ink systems also have a number of special qualities in the market for special applications. The demands placed on the design of high-quality packagings are increasing, and materials such as glass and metal are being used more and more frequently. With its very good adhesive properties, PVB as a binder enables printing on many different materials such as polyolefins, metal, cellulose acetate, polyester, cellophane, polyamide and polystyrene. PVB printing inks are also characterised by low solvent retention, good rheological properties and high resistance to moisture. They thus provide the basis for high-quality special printing inks, for example in combination with metallic pigments for label printing, as well as for glass inks, for example for cosmetic-product flacons.

The increasing demands placed on printing inks for packaging are a global trend. In Asia as well as in the Arab and African economic regions, conventional solvent-based printing inks in packaging printing are increasingly being replaced by ethanol-based ink systems such as PVB inks. Due to their good applicability and competitiveness, some consider NC and PVC ink systems as currently still having the edge. However, the increasing demand for environmentally-friendly and high-performance inks is permanently changing the market, with printing inks based on PVB opening up new opportunities and possibilities for packaging printing in the future.

news-267 Wed, 05 Jul 2017 08:00:00 +0200 Co-operation of Polymaker and Kuraray: 3D printing filament based on Mowital® https://www.mowital.com/newsroom/detail-view/news/co-operation-of-polymaker-and-kuraray-3d-printing-filament-based-on-mowitalr/?tx_news_pi1%5Bcontroller%5D=News&tx_news_pi1%5Baction%5D=detail&cHash=bf84f3de1235b76cf16f000043eae38d Hattersheim, July 5th, 2017. Based on its co-operation with Kuraray, Polymaker is now launching PolySmooth™, the first PVB-based 3D printing filament. This filament, whose main component is Kuraray’s polyvinyl butyral resin Mowital®, marks a breakthrough in filament-based 3D printing. Due to its excellent ‘smoothability’, objects printed in PolySmooth™ and post processed with Polymaker’s Micro-Droplet Polishing™ technology show such smooth and bright surfaces that they can compete with industrially-manufactured injection molded parts.    
Polymaker’s material scientists worked closely with the Kuraray team in the development of PolySmooth™. “Mowital® is the ideal basis for our formulation”, says Dr. Xiaofan Luo, the Co-Founder and President of Polymaker: “We tested many different PVB raw materials and Mowital® was clearly the best in terms of quality and consistency. With this product we were able to significantly improve the surface properties of 3D printed parts.”

“The use of Mowital® in 3D printing makes it possible to print objects with high surface quality at home too“, explains Jörg Bruss, Director, Global Business - Technical Resin at Kuraray. “We are looking forward to continuing to work with Polymaker. Together, we will  expand the market share of PVB in 3D printing.”

A bright result
What really makes this launch a landmark in 3D printing is the unique ‘smoothability’ of PolySmooth™. When a 3D model printed in PolySmooth™ is placed inside the Polysher™, the dedicated post-processing machine for PolySmooth™, an ultrasonic nebulizer creates a very fine mist of Isopropanol (IPA) that engulfs the model. Due to the filaments excellent solubility in alcohols, the IPA mist inside the Polysher™ rapidly melts the surface of the PolySmooth™ model. This process fuses the layers together and levels out any unevenness on the surface, turning a rough layered matte surface into a watertight glossy object – a true highlight in filament based 3D printing. This means that users will be able to produce 3D objects at home to an industry standard.


Outstanding material properties
In comparison to the current standard materials for filament-based 3D printing, PolySmooth™ displays outstanding printability, excellent mechanical properties and has a very minimal  odor during the printing process, making it suitable for both industrial as well as office/studio environments.   

Mowital® are specialty polymers with specific technical properties. The polymers can be customized for a wide range of applications. Polyvinyl butyral’s properties such as mechanical stability, resistance to light and excellent thermoplastic processibility contribute to the characteristics of PolySmooth™, whose great dimensional stability with minimal warping which makes it ideal for large prints.

news-266 Mon, 05 Dec 2016 14:32:00 +0100 Name change: Polyvinyl butyral - Pioloform® BL 16 will change to Mowital® BA 20 S https://www.mowital.com/newsroom/detail-view/news/name-change-polyvinyl-butyral-pioloformr-bl-16-will-change-to-mowitalr-ba-20-s/?tx_news_pi1%5Bcontroller%5D=News&tx_news_pi1%5Baction%5D=detail&cHash=e140e54c0b957b648848e8440e9d000a Please be informed that starting from January 1, 2017, the Pioloform® product name will be changed to Mowital®.
This name change is part of a global harmonization process of Kuraray’s polyvinyl butyral (PVB) brands. Mowital® is an existing global brand name of Kuraray PVB products. With this change the brand name Mowital® will be extended to all Kuraray PVB products. However, production processes will be unchanged and all regulatory information remains valid.

Pioloform® BL 16 will be included into our Mowital product type nomenclature and hence will be renamed  to Mowital® BA 20 S.

There will be a transitional period, during which the old and the new name will co-exist. Package branding for example, will show both, the old and the new product nomenclature, during the transition period. However, we are working hard to ensure that this period will be kept short and will not affect you in any way.  

Kuraray is a global manufacturer of polyvinyl butyral with over 70 years of experience. Our portfolio includes standard products and specialties. Mowital® meets all your requirements whether you are looking for low or high viscosity PVB.  The range includes products for a broad variety of applications.
