PVA 105 & PVA 205

        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.
        Liwei PVA can produce PVA 0599 to replace Kuraray PVA 105, and PVA 0588 to replace Kuraray PVA 205.

2. PVA 105 & PVA 205 Application:
PVA 105 is an environmental water-soluble high weight polymer, non-toxic, non pollution, has good film forming property, emulsifying property, bond property and the spining property, mainly used for textile materials, textile finishing agent, paper processing aids, adhesives, emulsifiers, polyvinyl alcohol acetal material, film and Vinylon, high strength and high modulus PVA short fiber, protein fiber.

Polyvinyl alcohol 205 (referred to as PVA 205) appears as white powder, is a use of a wide range of water-soluble polymers, plastics and rubber between the performance between the use of its fiber and non fiber can be divided into two major purposes.
