PVA

Polyvinyl alcohol (PVA), also known as Poval, is a water-soluble resin made through the polymerization and alcoholysis of vinyl acetate. It has unique qualities like high cohesion, strong membrane, smoothness, solvent resistance, gas inhibition, wear resistance, and waterproofing after special treatment.

Widely used in textile, construction, papermaking, packaging, timber processing, agriculture, printing, polymer chemicals, ceramics, iron and steel, electronics, electrolysis, electroplating, and more. Liwei produces PVA with consistent quality, high purity, white color, transparency, and stable viscosity.

It dissolves in water but not in common organic solvents, making it suitable for applications like paper sizing, textile warp sizing, adhesives, coatings, medicine, cosmetics, and more.
