Polyvinyl Alcohol

CheV Polyvinyl Alcohol(abbr.PVA) resin is a kind of heavy polymer.It is non-toxic, insipid and harmless. CheV-PVA is water-soluble and the solvent provides good viscosity and film building. It can withstand oils, lubricants, hydrocarbons and most other organic solvents. CheV-PVA has better chemical stability and insulatibility, and provides ease in firm building. It posses the typical chemical properties of polyols and can carry out process of esterification, etherealization, aceatalization etc.
