High Purity CAS 9003-39-8 Polyvinylpyrrolidone / Pvp K30 / Pvp K90
Polyvinylpyrrolidone (PVP) is a nonionic polymer that is the most characteristic, best-studied and most widely used of the N-vinyl amide polymers. It has developed into a series of homopolymers, copolymer and cross-linked polymer products with a relative molecular mass ranging from thousands to more than one million, and has been widely used for its excellent and unique properties.

In Pharmaceutical Industry
PVP-K possess excellent adhesive,film-forming,dispersing and thickening properties,and are widely used in the pharmaceutical industry.
Low molecular weight PVP-K, often used as a solubilizing agent, crystallization inhibitor and suspension stabilizer in injection and ophthalmic formulations such as PVP K12,K15,K17.
Medium Molecular PVP-K, often used as binder in tablets,capsules and granules, as a stabilizer for oral suspensions,film-forming agent,solubilizing agent, dispersant for pigments, as an enzyme stabilizer and to improve bioavailability such as PVP K25,K30.
High molecular PVP-K, as highly effective binder, often used as stabilizer in oral and topical suspension, as a thickener, hydropylizing agent such as PVP K90.
