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
  • toughness
  • water resistance
  • solubility in non-polar solvents
  • compatibility with non-polar polymers
