What is pva polyvinyl alcohol?

CPVA resin is a kind of heavy polymer. It is usually a white or slight yellow floccules, flake, granular or powdery in appearance. 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 barrier properties, and has typical chemical properties of polyols and can make esterification

 

Function 

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 and butyral resins;
4. In lumbering and paper-making industries, they can be used as adhesives;
5. In petroleum exploitation, they can be used as well-cementing agents

Application

PVA is a widely used water-soluble polymer that can quickly dissolve in water to form a stable colloid. Its performance is between that of plastic and rubber. In addition to being used as a fiber raw material, it is also widely used in the production of coatings, adhesives, paper processing agents, emulsifiers, dispersants, films and other products. Its application range covers textiles, food, medicine, construction, wood processing, papermaking, printing, agriculture, steel, etc Polymer chemical industry and other industries.
