 Polyvinyl Alcohol PVA 1492

Polyvinyl Alcohol is a kind of non-ionic linear high polymer. It is non-toxic, non-smelly, and it looks white or light yellow, in the form of floccules, flakiness and solid powder. Its molecular formula is (C2H4O)n, of which "n" refers to the average degree of polymerization and the molecular weight is 44n. For example, PVA 1788, 17 means the average degree of polymerization, and 88 means the alcoholysis degree. Polyvinyl alcohol (PVA) is high polymer with excellent characters to dissolve easily in water but not to dissolve in common organic solvent and organic acids, and with excellent film-forming property, oil resistant, chemical-resistant. It can react with formaldehydes to form polyvinyl acetal.
