Factory Quality CAS 9003-39-8 Polyvinylpyrrolidone Pvp USP/Ep/ Bp Pvp K17 / Pvp K25 / Pvp K30 / Pvp K60 / Pvp K90

1.Polyvinylpyrrolidone PVP is one of the three new pharmaceutical excipients. It can be used as a cosolvent for tablets, granules, injections, glidants for capsules, dispersants for liquid preparations and colorants, enzymes and heat-sensitive drugs. Stabilizer, co-precipitating agent for poorly soluble drugs, detoxifier and lubricant for eye drops, etc.
2.Industrially used as foaming polystyrene additives, gelling agents, stabilizers, fiber treatment agents, paper processing aids, adhesives, and thickeners for suspension polymerization.
3.Polyvinylpyrrolidone PVP and its copolymer CAP are important raw materials for cosmetics. They are mainly used as hair-retaining agents. The film formed on the hair is elastic and shiny, has excellent combing performance, does not stick to dust, and uses different specifications of resins to meet Various relative humidity and climatic conditions, so it is an indispensable raw material for styling hair cream, hair spray and mousse. It can also be used as a skin care moisturizer in cosmetics, a grease base material, a hair dye dispersant, and a foam stabilizer to improve the consistency of shampoos.

4.Coatings and pigments

Paints and coatings coated with PVP form a transparent film without affecting the natural color, improve the gloss and dispersibility of paints and pigments, improve thermal stability and improve the dispersibility of inks and inks.

5.Textile

PVP has a good affinity with many organic dyes. It can be combined with hydrophobic synthetic fibers such as polyacrylonitrile, ester, nylon and fibrous materials to improve dyeing power and hydrophilicity. Kirsh Y E et al. reported that after the graft copolymerization of PVP and nylon, the fabric produced has improved wet wrinkle resistance and moisture resistance.

6.Polymer Surfactant

Polyvinylpyrrolidone as a polymer surfactant, in different dispersion systems, can be used as a dispersant, emulsifier, thickener, leveling agent, particle size regulator, anti-reprecipitation agent, coagulant, co-solvent and washing agent Agent.

7.Catalyst preparation
As an active agent to stabilize colloidal particles, it is used in the preparation process of core-shell catalysts.
