Introductions of polyvinyl alcohol PVA
Polyvinyl alcohol (PVA) 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 (PVA) powder series of products is specialized in construction industry as an additive in all kinds of dry powder putty, dry mortar, tile adhesive, especially used for building putty and Mortar, improving the flexibility, water retention and increase viscosity of mortar and putty. It's adhesion very good and used to be widely with paper making, sizing material for textile, adhesive, film, and dry mortar field.
