PVA(Polyvinyl alcohol) is a polymer.it's usually a white or slight yellow floccule.flake,granular or powder solid.it's nontoxic,tasteless,non-polluting, PVA is a water-soluble resin and has good chemical stability. it also has good adhesion.film-forming ability, insulation, oil resistance,abrasion resistance and gas barrier properties,and has typical chemical properties of polyols.and can make esterification. etherification and acetalization reactions.
PVA products have a wide range of uses in the textile industry,they are mainly used as yarn pulp, fabric finishing agents,and raw materials ofvinylon fibers. in the construction and decoration industries, they ccan be used as mortar cement additives,paint additives for interior andexterior walls, and molding palte adhesives, in the chemical industry,they can be used as polymerization emulsifiers, dispersants and raw materials for the production of PVF,acetalal and butyral resins, in lumbering and paper-marking industries,they can be used as adhesives, in agriculture, they can be used as soil imporvers pesticide-adhesion synergist and PVA film, in petroleum exploitation. they can be used as well-cementing agents, in addition, they can also be used in cosmetics, plharmaceuticals.printing.ceramics, steel. Electronics, electroplating and so on.
PVA grades are the follows:
<1> PVA1799 <8> PVA2088
<2> PVA2099 <9> PVA2288
<3> PVA2299 <10>PVA2488
<4> PVA2499 <11> PVA2499
<5> PVA2699 <12> PVA2688
<6> PVA0588
<7> PVA0599
