Polyvinyl alcohol is an organic compound with the chemical formula [C2H4O] n. It appears as a white flake, flocculent, or powdered solid and has no odor. Soluble in water (above 95 ℃), slightly soluble in dimethyl sulfoxide, insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc. Polyvinyl alcohol is an important chemical raw material used in the manufacturing of polyvinyl acetals, gasoline resistant pipelines and vinylon, fabric treatment agents, emulsifiers, paper coatings, adhesives, adhesives, etc.

Some main characteristics of Pva: 1. Solubility: PVA can dissolve in water and form a transparent solution. This makes it an ideal adhesive, coating, and coating for many applications. 2. Good adhesion: PVA can adhere well to many different surfaces, including paper, wood, fabric, and plastic. 3. Good elasticity: PVA has good elasticity and can maintain its shape and performance in constantly changing environments. 4. Water resistance: PVA dissolves in water, but once dried, it can effectively resist water erosion and damage. 5. High molecular weight: PVA has a high molecular weight, which gives it high strength and durability.

PVA is widely used in many different applications, including: 1 Adhesive: PVA is an ideal adhesive that can be used for bonding materials such as paper, wood, fabric, and plastic. 2. Coatings and coatings: PVA can be used to make transparent coatings and coatings, which can protect the surface and increase glossiness. 3. Medical application: PVA can be used to make medical dressings and artificial organ because of its good biocompatibility. 4. Cellulose manufacturing: PVA can be used to manufacture cellulose, which is a high-strength and durable cellulose material. 5. Paper manufacturing: PVA can be used to manufacture high-quality paper because it can increase the strength and durability of the paper. In terms of knowledge expansion, we can learn that PVA can also be used to manufacture gel, foam, plastic and other materials. In addition, PVA can also be mixed with other materials to create new materials with specific properties. For example, mixing PVA with polyethylene ether can produce materials with higher strength and better durability.
