Polyvinyl Alcohol Powder has excellent film forming, , and properties. It is also resistant to oil, grease and . PVA Powder is odorless and nontoxic. It has high tensile strength and flexibility, as well as high oxygen and aroma barrier properties. However these properties are dependent on , in other words, with higher humidity more water is absorbed. The water, which acts as a plasticiser, will then reduce its tensile strength, but increase its elongation and tear strength. PVA is fully degradable and is a quick dissolver. PVA has a melting point of 230C and 180190C for the fully hydrolysed and partially hydrolysed grades. It decomposes rapidly above 200C as it can undergo at high temperatures.
Application:
1.In the textile industry , they are mainly used as yarn pulp, fabric finishing agents, and raw materials of vinylon fibers;
2. In the construction and decoration industries, they can be used as mortar cement additives, paint additives for interior and exterior walls, and molding plate adhesives;
3.In the chemical industry, they can be used as polymerization emulsifiers, dispersants, and raw materials for the production of PVF, acetal and butyral resins;
4. In lumbering and paper-making industries, they can be used as adhesives;
5. In agriculture, they can be used as soil improvers, pesticide adhesion synergist and PVA film;
6. In petroleum exploitation, they can be used as well-cementing agents.
7. In addition, they can also be used in 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. Polyvinyl Alcohol White Powder 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.
