Polyvinyl Alcohol (abbreviated as PVA) is a kind of water-soluble resin produced by polymerization and alcoholysis of vinyl acetate. Due to its unique features of high cohesiveness, membrane tenacity, smoothness, solvent resistance, gas inhibitor, wear resistance, protective colloid, and waterproof after specially treated, polyvinyl alcohol is widely applied in textile, building, papermaking, packing, timber processing, agriculture, printing, polymer chemical, ceramic, iron and steel, electronic, electrolytic, electroplating and other industries. As excellent synthetic fibers, it can also be spun and acetalized to make vinylon fiber.

Properties :

• Polyvinyl alcohol is high polymer with excellent characters to dissolve easily in water but not to dissolve in common organic solvent and organic acids
• Excellent film-forming property
• Oil resistant
• Chemical-resistant
• Can react with formaldehydes to form polyvinyl acetal
