Properties of PVB
Depending on the degree of acetalisation, or the residual PVA content, the individual Mowital® grades display different physical and chemical properties. The molar mass, or the degree of polymerisation, is of great importance for the thermal and mechanical properties and the viscosity in solution.
- molecular weight
- solution viscosity
- melting and softening range
- water resistance
- solubility in non-polar solvents
- compatibility with non-polar polymers
