Introduction; PVP for short, is a non-ionic polymer compound, is N-vinylamide It is the most characteristic, deepest and most widely studied fine chemical species among polymers. It has developed into three categories of non-ionic, cationic and anionic, three specifications of industrial grade, pharmaceutical grade and food grade, and a series of homopolymer, copolymer and cross-linked polymer products with relative molecular weight ranging from thousands to more than one million , and has been widely used for its excellent and unique properties.

Uses: As a synthetic water-soluble polymer compound, PVP has the general properties of water-soluble polymer compounds, such as colloidal protection, film-forming, cohesiveness, hygroscopicity, solubilization or coagulation, but its most distinctive features, Therefore, people pay attention to its excellent solubility and physiological compatibility. Among synthetic polymers, PVP is soluble in both water and most organic solvents, with low toxicity and good physiological compatibility, especially in medicine, food, cosmetics, which are closely related to people's health. In the field, with the price reduction of its raw material butyrolactone, it will show a good prospect for its development.
