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 help them comply with higher emission limits, for example. 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/zh/news/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.

news-278 Tue, 12 Mar 2019 16:08:28 +0100 “ PVB材料正将3D打印推向一个新的发展阶段” https://www.mowital.com/zh/news/detail-view/news/pvb-materials-are-taking-3d-printing-to-the-next-level-of-evolution/?tx_news_pi1%5Bcontroller%5D=News&tx_news_pi1%5Baction%5D=detail&cHash=cf1055e66ab1a6999d3bce8bd9539d7a 基于Mowital的PVB打印丝材,使得3D打印的质量和效率更高。可乐丽研发实验室负责人 Florian Mummy 博士访谈
哈特尔斯海姆/美茵河畔法兰克福,2019年3月。相比 PLA 或 ABS 丝材,基于 Mowital材料的 PVB 打印丝材为3D打印提供了显著优势——当前如此,未来亦是如此。Florian Mummy 博士是世界领先特种化学品制造商可乐丽(Kuraray)的研发实验室负责人。在接下来的采访中,他说明了基于PVB 的丝材为何能够显著改善 3D 打印的工艺及品质。由于此类丝材具有独特的特性,在保护环境的同时它们将构成未来生产的基础——

Mummy 博士,您认为 3D 打印未来将会有怎样的发展?
Florian Mummy 博士:我们目前正处于三个发展阶段中的第二阶段。过去3D 打印主要被用在开发工作中快速制造原型。如今一些公司已开始采用 3D 打印机为终端应用生产大量独立功能部件。未来,增材制造将成为工业 4.0 的一项标准。使用 3D 打印机以工业化规模制造客户定制产品也将成为日常生活的一部分。不过我们离此目标尚有很大距离。

为此肯定有一些待克服的挑战吧?
Mummy: 是的,因为要转向大规模生产,首要任务就是改善 3D 打印的质量及复现性。目标是达到相当于注塑成型的质量水平。其中一项难点在于,打印的零部件所能达到的机械性能难以预测。因为工艺决定了打印材料(丝材)需要逐层增加。如果各层之间的粘附出现问题,就会导致部件故障。众所周知常用的聚丙交酯(PLA)基或丙烯腈-丁二烯-苯乙烯共聚物(ABS)基打印丝材就有这个问题。部分或全部由聚乙烯醇缩丁醛(PVB)如Mowital制成的打印材料则在这方面具有优势。

Mowital 在 3D 打印中具有哪些优势呢?
Mummy: 使用基于 Mowital 的打印丝材能够生产出可承受更高机械负荷的 3D 物体。使用该材料时,硬度和断裂强度尤其可得到显著提升。Mowital 具有出色的粘接力——这是各打印层持久粘结的一个关键点。该材料的另一项优势则是对健康无害。使用基于 Mowital 的丝材打印时,几乎不会产生任何排放物或难闻的气味。此外,使用 PVB 打印丝材还可实现最高品质的表面效果。  

具体过程是怎样的呢?
Mummy: 3D 打印机输出的对象表面由于为多层所组成,最初是粗糙的。要获得平滑的表面,还须经过一种特殊的抛光处理,将微小酒精液滴气溶胶喷涂在3D 打印件的表面。各层融合为一体,同时使该物体固化,表面的任何不均匀都被拉平。形成了视觉上颇具吸引力、平滑且有光泽的表面。相对于传统的 PLA 和 ABS 丝材,基于 Mowital 的打印丝材可配合使用对环境和健康无害的乙醇作为气溶胶材料。至于纯 PLA 丝材,则根本无法通过抛光获得平滑表面。而与在ABS 丝材中使用的具有麻醉效果的丙酮不同,乙醇有助于更加精确地控制抛光过程,从而实现更高品质。

平滑表面用于生产时尚、富有设计感的产品?
Mummy:
用作打印丝材的高聚物相容性决定了以多种材料所制成物体的粘结牢固程度。Mowital 可与诸多聚合物相容,因而使得全新的材料组合成为可能。在可乐丽位于德国法兰克福 Höchst 工业园区的研发基地我们有自己的 3D 打印实验室,供我们与 POVAL 部门的同事共同研发和测试各种 基于PVA 和 PVB 的丝材。测试表明,PVB 打印丝材配合 Mowiflex 3D 2000 使用可产生极佳效果。

Mowital 可与诸多聚合物相容。如何在 3D 打印中利用这一特性呢?
Mummy: 用作打印丝材的高聚物相容性决定了以多种材料所制成物体的粘结牢固程度。Mowital 可与诸多聚合物相容,因而使得全新的材料组合成为可能。在可乐丽位于德国法兰克福 Höchst 工业园区的研发基地我们有自己的 3D 打印实验室,供我们与 POVAL 部门的同事共同研发和测试各种 基于PVA 和 PVB 的丝材。测试表明,PVB 打印丝材配合 Mowiflex 3D 2000 使用可产生极佳效果。

也就是基于可乐丽PVA 的辅助丝材……
Mummy: 没错。基于 Mowital 的打印丝材,例如丝材制造商 Polymaker 提供的 PolySmooth,可与我们的 Mowiflex 3D 2000 非常牢固地粘在一起。该组合能够发挥出材料的完整潜力,提供出色的打印品质。例如不会因支撑材料与打印丝材没有充分粘合而出现缺陷。

基于PVB 的打印丝材至今仍是小众产品。这种情况会改变吗?
Mummy: Exactly. Printing filaments based on Mowital, like PolySmooth from filament manufacturer Polymaker for example, and our own filament Mowiflex 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: 我敢肯定。我期望未来PVB材料在3D打印中的重要性将会显著提高。基于 Mowital 的打印丝材优势巨大。该材料能够实现更高的品质,同时使制造工艺更加安全简便。凭借其出色的材料特性,我们正在创造未来的 3D 打印解决方案。

德国工程联合会最新一项研究表明,包装印刷的全球销售额每年增长5%以上。与此同时,消费者、行业和立法者对于印刷油墨的要求也在增加。Kuraray作为世界领先的特种化学品生产商和印刷油墨行业供应商之一,正在关注两个主要趋势:人们对于环保型和兼容型油墨的意识与日俱增,同时,对于定制专用油墨的需求也不断提升。针对这两项发展趋势,例如基于我们PVB树脂Mowital的聚乙烯醇缩丁醛(PVB)油墨系统优势明显。

适用于食品包装的安全油墨
消费者保护团体一再要求在食品包装印刷上弃用聚氯乙烯(PVC)基油墨。由于这种油墨可能含有残余单体,并引起过敏反应,因此,许多食品集团和平价超市为其产品包装设定了高标准。在瑞士之后,我们预期德国也会针对在欧洲经济区内使用的食品包装出台更高要求的印刷油墨规定。与此同时,PVB油墨正在变得越来越重要:这些不含对健康有害的污染源,因此对消费者完全无害。

PVB与其他印刷油墨组分良好兼容,这是其目前主要用于食品包装印刷的原因之一。凭借出色的特性,PVB可为要求苛刻的包装应用打造持久的印刷效果。改性PVB印刷油墨耐受热处理和蒸汽处理,因此可用于例如灭菌包装。在微波炉中,PVB油墨不会释放有害物质,因此在即食食品的包装中完全无害。此外,PVB油墨在冷冻包装中也具有优势。与硝化纤维素(NC)油墨相比,PVB油墨在极低温度下仍然可保持更柔软、更柔韧的状态,而无需添加增塑剂。同时,这种油墨亦符合宠物食品包装的高标准。

让精致的包装设计熠熠生辉
PVB油墨系统的独特功能同样令其能够在特殊应用市场中施展用武之地。对于高品质包装设计的要求越来越高:玻璃和金属等材料的使用率不断提升。PVB具有优异的粘合特性,可作为印刷粘合剂应用在多种材料上,比如聚烯烃、金属、醋酸纤维素、聚酯纤维、玻璃纸、聚酰胺和聚苯乙烯。除此之外,PVB印刷油墨还具有低溶剂残留、良好的流变性和较高的耐湿性等特性。因此,这些为高品质专用印刷油墨,例如与金属颜料组合用于标签印刷以及玻璃油墨,例如用于化妆品瓶,提供了基础。

对于包装用印刷油墨的需求日益增长是一种全球趋势。在亚洲以及阿拉伯和非洲经济区,包装印刷中传统的溶剂型印刷油墨正在逐渐被乙醇基油墨系统(例如PVB油墨)取代。一些NC和PVC油墨系统鉴于其同样良好的适用性和竞争力,目前仍然占据优势。然而,对于环保和高性能油墨日益增长的需求正在持续地改变着市场,PVB基油墨为未来的包装印刷开启了新的机遇和机会。

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/zh/news/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.

Mowital® − the brand for  best connections.
