Polyvinyl alcohol (PVA) is a non-polluting water-soluble polymer, usually white or light yellow flocculent, flake, granular or powder solid. Its performance is between plastic and rubber. It has good adhesion, film forming, insulation, oil resistance, wear resistance and gas resistance.

　　Application Area

　　1.In the textile industry , they are mainly used as yarn pulp, fabric finishing agents, and raw materials of vinylon fibers;

　　2.In the construction and decoration industries, they can be used as mortar cement additives, paint additives for interior and exterior walls, and molding plate adhesives;

　　3.In the chemical industry, they can be used as polymerization emulsifiers, dispersants, and raw materials for the production of PVF, acetal and butyral resins;

　　4.In lumbering and paper-making industries, they can be used as adhesives;

　　5.In agriculture, they can be used as soil improvers, pesticide adhesion synergist and PVA film;

　　6.In petroleum exploitation, they can be used as well-cementing agents.
