Product Description

Polyvinyl alcohol (PVA) resin is a kind of heavy polymer. 
It is usually a white or slight yellow floccules, flake, granular or powder in appearance. 
PVA is non-toxic, insipid and non-polluting. PVA is a kind of water-soluble resin with good chemical stability.
It also has good adhesion,film-forming ability, insulation, oil resistance, abrasion resistance and gas berrier properties, and has typical chemical properties of polyols and can make esterification, etherification, acetalization reactions.
It usually used into the Textile industry,construction and decoration industries, chemical industry, paper-making, agriculture, petroleum exploitation, and also cosmetics, pharmaceuticals, printing, ceramics, steel, electronics, electroplating and so on.
