Introduction ofPVA polyvinyl alcohol
PVA ，pva viscosity(polyvinyl alcohol)Other Name：poly(vinyl alcohol，viny)alcohol polymer，poval，For Short PVACAS No:9002-89-5Molecular formula: [C2H4O]nPolyvinyl alcohol resin series of products are white solid, It has three species: floc, granular, and powder. non-toxic tasteless, non-polluting, can be dissolved in 80—90℃ water. According to the degree of alcohol solution, PVA can be divided into partially hydrolyzed and Fully Hydrolyzed. Its aqueous solution has good adhesion and film-forming properties, and is capable of most organic solvents, such as oil, lubricants and hydrocarbons, and is characterized by esterification of Long-chain Polyols, Etherification and acetal.
Use and application ofpolyvinyl alcohol
Because of its unique strength, adhesion, flexibility, smoothness, oil resistance, solvent resistance, colloid protection, gas resistance, abrasion resistance and water resistance through special treatment, PVA therefore, in addition to making fiber raw materials, but also a large number of products used in the production of paints, adhesives, paper processing agents, emulsifiers, dispersants, films and other product applications throughout the textile, food, medicine, construction, wood processing, paper, printing, agriculture, steel, polymer chemicals and other industries. The most popular types of PVA are , and .
