Polyvinylpyrrolidone, or PVP, is a non-ionic polymer that is the most distinctive, best-studied and widely studied fine chemical among N-vinylamide polymers. Has developed into non-ionic, cationic, anionic 3 categories, relative molecular weight from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products, and with its excellent unique properties have been widely used. Polyvinylpyrrolidone, as a polymer surfactant, can be used as dispersant, emulsifier, thickener, leveling agent, particle size regulator, anti-reprecipitating agent, coagulant, co-solvent and detergent in different dispersion systems.<\/p>\n

Application: Polyvinylpyrrolidone can combine with phenols and alkaloids to form a complex to remove phenols and alkaloids from plant samples, which can prevent these substances from modifying proteins and interfering with spectrophotometry to measure protein content; Increased enzyme stability. PVP is widely used as an excipient in pharmaceutical preparations.<\/p>\n

K30: \u22665ppm (ICP-MS)<\/p>\n

What is the particle size?<\/p>\n

The average particle size is shown below.<\/p>\n

K90, K85: about 300\u03bcm<\/p>\n

K30: About 100\u03bcm<\/p>\n

How to store?<\/p>\n

It will absorb moisture from the air, so it is recommended to use a container that is isolated from the air. (e.g. Aluminum foil inner bag, heat sealing)<\/p>","protected":false},"excerpt":{"rendered":"
