Polyvinyl Alcohol (PVA)

Whatsapp Order

Polyvinyl Alcohol (PVA) is a synthetic, water-soluble polymer made by the hydrolysis of polyvinyl acetate. It is known for excellent film-forming, emulsifying, and adhesive properties. PVA is widely used across industries for applications requiring biodegradable, non-toxic, and flexible materials. It offers good chemical resistance, mechanical strength, and compatibility with other polymers and additives.
