PVA :: Polyvinyl alcohol

short description_EN: 
PVA is a macro molecule produced through saponification of polyvinyl acetate. It contains acetyl groups next to the vinyl alcohol units.

A distinction is made between fully hydrolysed and partly hydrolysed types, which have various properties and application possibilities.

Fields of application:

  • Raw material to produce adhesives: Advantages are the uniform structure and the high gluing power at low usage
  • In the paper industry, for producing raw and coated paper, PVA is distinguished by high pigment and fibre-binding strength, excellent carrying characteristics for whiteners, good applicability as a protective colloid. Here, mostly low viscosity, fully hydrolysed PVA types are used.

PVA offers many more uses, for example as a protective colloid in the textile industry, or as a washable binding agent for moulded ceramics, to name but two.
