Polyvinyl alcohol (abbreviated as PVA) also can be called Poval 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. Liwei can produce PVA series in large quantity with polymerization degrees of 1,700-2,800 and alcoholysis degrees of 88-99.9 (mol/mol) %, featuring consistent quality, high purity, white color, high transparency, and stable viscosity. Apart from production of general PVA readily available for customers, the company also develops a variety of PVA tailored for customers specific purposes.
