Description
What Is Polyvinyl Alcohol?
Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer widely used across industries such as packaging, textiles, adhesives, construction, and pharmaceuticals. Unlike many plastics, is biodegradable under specific conditions, making it an environmentally favorable option.
It is produced through the hydrolysis of polyvinyl acetate, resulting in a versatile material with strong film-forming, emulsifying, and adhesive properties.
