Polyvinyl alcohol (PVA for short), organic compound, white flake, flocculent or powdered solid, non-toxic, tasteless, pollution-free, can be dissolved in 80--90 °C water. Slightly soluble in dimethyl sulfoxide. Its aqueous solution has good adhesion and film-forming properties; It has chemical properties such as esterification, etherification and acetalation of long-chain polyols. It is a water-soluble polymer with a wide range of uses, its performance is between plastic and rubber, and its uses can be divided into fiber and non-fiber two major uses.
