CAS Number: 9002-89-5

Polyvinyl alcohol (PVA), a white/yellowish granule or powder, is a stable, non-toxic, and water-soluble polymer. PVA possesses good film-forming property, and the film formed from it has excellent adhesion, solvent-resistance, abrasion-resistance, high tensile strength, and great oxygen barrier property. Due to PVA possesses both hydrophilic and hydrophobic functional groups, it can act as surfactant, and can be used as a protective colloid in polymer emulsification and suspension polymerization.
