Audited Supplier Polyvinyl alcohol powder pva 1788 PVA 2488 construction grade
Description
Polyvinyl Alcohol powder pva 1788 PVA 2488 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.
Characteristic
Polyvinyl Alcohol powder pva 1788 PVA 2488 PVA resin is a kind of heavy polymer,it is non-toxic, insipid and harmless. PVA is water-soluble and the solvent provide good viscosity and film building. It can withstand oils, lubricants, hydrocarbons and most other organic solvents. PVA has better chemical stability and insulatibility, and provide ease in firm building; It possess the typical chemical properties of polyols and can carry out process of esterification, etherealization, acetalization etc.
