Product Description

Polyvinyl Alcohol Pva Podwer 1788 2488 2688

Polyvinyl alcohol (PVOH, PVA, or PVAL) is produced by hydrolysis of polyvinyl acetate. The amount of hydroxylation determines its physical and mechanical properties. The dry polymer is a hard, colorless and odorless crystalline thermoplastic with a Tg of about 375 K. It is highly water soluble, fully biodegradable but resistant to solvents and oils, and has exceptionally good adhesion to cellulose and other hydrophilic surfaces.

Furthermore they are fully biocompatible, biodegradable and nontoxic, making them especially suited for packaging of food, drugs, and cosmetics.
