PVA film is a water-soluble film made from polyvinyl alcohol.
It is available in a wide range of types, from those that are soluble in cold water to those that are soluble in hot water, to respond to diverse needs.
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.

Polyvinyl alcohol (PVA) resin is a polymer. Ití»s usually a white or slight yellow flocculent, flake, grnular or powdery solid. Its molecular formular is (C2H4O)n. Ití»s non-toxic, insipid, non-polluting. PVA is a water-soluble resin and has good chemical stability. It also has good adhesion, film-forming alibility, insulation, oil resistance, abrasion resistance and gas barrier properties, and has typical chemical properties of polyols. And can make esterification, etherification, acetalation reactions.
PVA application
PVA products have a wide range of uses.
a.In the textile industry, they are mainly used as yarn pulp, fabric finishing agents, and raw material of vinylon fibers.
b.in the construction and decoration industries, pva can be used as mortar cement additives, paint additives for interior and exterior walls, and molding plate adhesives
c. in the chemical industry, PVA can be used as polymerization emulsifiers, dispersants, and raw materials for the production of PVF, acetalal and butyral resins.
d. in lumbering and paper making industries, PVA can be used as adhesives.
e. in agriculture, PVA can be used as soil improvers, pesticide adhesion synergist and PVA film.
