Polyvinyl Alcohol (PVA) is a water-soluble synthetic polymer derived from the hydrolysis of polyvinyl acetate. It is characterized by its exceptional film-forming, emulsifying, and adhesive properties. PVA is renowned for its high tensile strength, flexibility, and excellent barrier properties against oils, greases, and solvents. As a non-toxic and biodegradable polymer, it is widely used in diverse industrial, commercial, and biomedical applications.

Application:
- In the textile industry, they are mainly used as yarn pulp, fabric finishing agent and raw materials of vinylon fibers.
- In the construction and decoration industries, PVA can be used as mortar cement additives, paint additives for interior and exterior wall sand molding plate adhesives.
- In the chemical industry, PVA can be used as polymerization emulsifier dispersants, and raw materials for the production of PVF, acetal and butyral resins.
- In lumbering and paper making industries, PVA can be used as adhesive
- In agriculture: PVA can be used as soil improves, pesticide adhesion synergist and PVA film.
- In petroleum exploitation, PVA can be used as well-cementing agents.
- In addition PVA can also be used in cosmetics, pharmaceuticals, printing, ceramics, steel, electronics, electroplating and so on.
