Poly vinyl Alcohol（PVA）

CAS No.9002-89-5

MF:C2H4O

EINECS:209-183-3

Polyvinyl Alcohol is a few kind of synthetic with water souble high-molecular polymer.  The main specification includes degree of polymerization & alcoholysis and other specical performance. Polyvinyl Alcohol is manufactured by polymerization of vinyl acetate in methanol solvent, then undergoing alcoholysis via advanced belt-process of low-alkali. After grining, drying and packing, the end PVA products are achieved.

PVA has a unique strong adhesion and film flexibility, smoothness, oil resistance, solvent resistance, protective colloid, gas block, wear resistance, and the special treatment of water resistance, therefore, except for fiber raw material has been used in the production of coatings, adhesives, paper processing agent, emulsifier, dispersant, film and other products, range of application in textile, food, medicine, architecture, wood processing, paper making, printing, agriculture, steel and polymer chemical industry
