Polyvinylpyrrolidone 30 9003-39-8
Application
Application of industrial grade PVP: PVP-K series can be used as film agent, thickener, lubricant and adhesive in the daily chemical industry, used for spraying, mousse, hair fixing gel, hair fixing liquid, etc. Hair dyes, modifiers, foam stabilizers for shampoos, dispersants and affinity agents in wave setting agents for skin care. Adding PVP to creams and sunscreens can enhance the moisturizing and lubricating effects. Secondly, adding polyvinylpyrrolidone 30 to the detergent has a good anti-rotation effect and can enhance the cleaning ability.Application of PVP in industrial and high-tech fields: PVP can be used as surface coating agent, dispersant, thickener, adhesive, PVP can improve the adhesive in pigments, printing inks, textiles, printing and dyeing, and color picture tubes. Bonding performance to metals, glass, plastics and other materials. In addition, PVP is emerging in separation membranes, ultrafiltration membranes, microfiltration membranes, nanofiltration membranes, petroleum extraction, photo-solid resins, paints and coatings, optical fibers, laser discs, etc. The application of high-tech fields is also becoming more and more extensive. In short, the PVP series products have excellent performance and wide application. They are widely used in medicine, coatings, pigments, resins, fiber inks, adhesives, detergents, textiles and printing and dyeing additives. As a polymer surfactant, PVP can be used as dispersant, emulsifier, thickener, leveling agent, viscosity regulator, anti-reproduction liquid agent, coagulant, cosolvent and detergent in different dispersion systems.
