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 apperance.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, pape-rmaking,agriculture, petroleum exploitation,and also cosmetics,pharmaceuticals,printing,ceramics,steel,electronics,electroplating, and so on.

Polyvinyl alcohol is an excellent water-based adhesive. The general product is flake, granular or flocculent. It is not easily soluble in cold water. Heating is generally required during dissolution. After being finely pulverized and surface treated, it has better cold water dissolving performance. But because of its thermoplasticity, pulverization becomes particularly difficult. Our factory adopts a special liquid nitrogen low temperature cooling process to ensure that the powder of the crushed material is uniform. So that the material has excellent water solubility.
