White Granule Polymer Paper Sizing Chemicals Polyvinyl Alcohol PVA 1799 is a few kind of synthetic with water soluble high-molecular polymer. The main specification includes degree of polymerization & alcoholysis and other special performance. Polyvinyl Alcohol is manufactured by polymerization of vinyl acetate in methanol solvent, then undergoing alcoholysis via advanced belt-process of low-alkali. After grinning, drying and packing, the end PVA products are achieved.
