Polyvinyl alcohol (PVA) is an important water-soluble synthetic polymer made by alcoholysis or hydrolysis of polyvinyl acetate (PVAc). It appears as white to slightly yellow granules, powder, or flocculated solids.

PVA has become a chemical raw material with extremely wide applications. It's not only used as a base material for textile sizing, high-performance adhesives, paper treatment agents, and packaging films, but also, because of its good biocompatibility, in biomedical fields like drug carriers, medical dressings, and tissue engineering scaffolds. From traditional industries to high-tech frontiers, PVA plays an indispensable role.

EVA resin is widely used in areas like photovoltaic films, foamed materials, shoes, agricultural films, and wires and cables because it's thermoplastic and safe for food contact.
