Poly(vinyl alcohol) CAS#9002-89-5

Poly(vinyl alcohol) (PVA) is a water-soluble synthetic polymer derived from the hydrolysis of poly(vinyl acetate). It is renowned for its film-forming properties, biocompatibility, and high tensile strength. PVA is extensively used in the production of textiles, paper, and adhesives due to its excellent adhesive and emulsifying characteristics. Its water solubility and biodegradability make it a preferred material in various industrial applications, including packaging films and medical devices.
