Polyvinylpyrrolidone pvp 9003-39-8

Polyvinylpyrrolidone PVP appearance is white powder, non-toxic, non-irritating, hygroscopic, easily soluble in water, alcohol, amine and other organic solvents, with
It has excellent solubility, film formation, chemical stability, adhesion and complexation ability, and is widely used in medicine and cosmetics
And other industries.
Pharmaceutical industry
PVP is a new pharmaceutical excipient, mainly used as a co-solvent of tablets, pills, granular binders, injections, flow AIDS of capsules, etc. There are hundreds of drugs made of PVP products.
Cosmetics industry
PVP can be used as film agent, thickener, lubricant and adhesive in cosmetics industry, and used as spray agent, mousse and hair fixing gel. In skin care products and hair dye, modifier, shampoo, lip balm, deodorant, sunscreen, toothpaste and other aspects of the very suitable as accessories.
Other industries
Coatings, paints, inks as dispersant, thickening agent.
In agriculture, it can be used as a seed coating agent to act on the surface treatment of crops or other plant seeds.
Office supplies can be used as printer ribbon, ink, graphite, ink thickener, lubricant, dispersant, solid glue, adhesive raw materials, paper and so on.
In the water treatment industry, it can be used as a pore-causing agent for water treatment membrane (hollow fiber ultrafiltration membrane, sulfone, polysulfone).
Electronic battery, electroplating and other industries.
Application example
abluent
PVP has anti-fouling reprecipitation properties, can be used to prepare transparent liquid or heavy fouling detergent, in the detergent can prevent color conversion, enhance the cleaning ability, no irritation to the skin. For synthetic fibers, the performance is more prominent than that of carboxymethyl cellulose (CMC) detergent. In addition, PVP can be combined with borax and hydrogen peroxide solid in the formula of disinfection detergent, which has the function of bleaching and killing germs.
Textile printing and dyeing
PVP has a good affinity with many organic dyes, and the combination of hydrophobic synthetic fibers such as polyacrylonitrile, ester, nylon and fibrous materials can improve the dyeing power and hydrophilicity, so it is often used as bleach and levelling agent. However, the binding force of PVP and different dyes is different, so it can be used as an anti-dye.
Paints and pigments
PVP coated paint, coating film transparent without affecting the color, improve the gloss and dispersion of paint and pigment, improve thermal stability and improve the dispersion of ink and ink.
Polymer surfactant
PVP coated paint, coating film transparent without affecting the color, improve the gloss and dispersion of paint and pigment, improve thermal stability and improve the dispersion of ink and ink.
Water treatment industry
PVP can be used as the pore making agent of ultrafiltration membrane in the water treatment industry and has many excellent properties, which can effectively control the size of the membrane aperture and the distribution of the pores, increase the density of the membrane pores, improve the permeability of the membrane, and improve the hydrophilicity of the membrane surface. The ultrafiltration membrane industry generally chooses K30, which has narrow molecular weight distribution and good pore formation effect.
electroplate
In the electroplating industry, it is used as a leveling agent to fill sub-micron gaps on the surface of plated parts.
