Polyviny lacetate (PVA)

Polyvinyl acetate is a thermoplastic material with elastomeric properties. It is mainly used for hydrophilic coatings. It is also applied in adhesive tapes. PVA is the polymer of the monomere Vinyacetate which is not stable. 

Use of the abrevation PVA may cause confusion because this is also used for the the polymer Polyvinyl Alcohol.
