Product Description

Products Description of Poly(vinyl alcohol) CAS# 9002-89-5

Poly(vinyl alcohol) (PVA) is a versatile solid polymer in powder, flake or flocculent forms. Highly polar and hydroxyl-rich, it is water-soluble, has a stable 60–85°C glass transition temperature, and resists gasoline and acetone. Processable with hot hydroxyl solvents, it is widely used for chemical barrier applications.

Product Application of Poly(vinyl alcohol) CAS# 9002-89-5

Polyvinyl alcohol (PVA), a 2026 industrial manufacturing cornerstone, offers exceptional versatility. Used in textile sizing, construction adhesives, chemical emulsification, cosmetics thickening and paper stabilization, it also enables innovative eco-friendly films, agricultural soil conditioners and medical materials with reliable performance.
