pva (polyvinyl alcohol)

Descripción del producto

PVA properties:
Polyvinyl alcohol (PVA) resin is a polymer. It’s usually a white or slight yellow flocculent, flake, grnular or powdery solid. Its molecular formular is (C2H4O)n. It’s non-toxic, insipid, non-polluting. PVA is a water-soluble resin and has good chemical stability. It also has good adhesion, film-forming alibility, insulation, oil resistance, abrasion resistance and gas barrier properties, and has typical chemical properties of polyols. And can make esterification, etherification, acetalation reactions.
