Product Overview
Description
(polyvinyl pyrrolidone) (PVP,) is a kind of Nonionic polymer compound, which is the most characteristic N-vinyl amide polymer and has been studied deeply and widely. It has been developed into a series of homopolymers, copolymers and crosslinked polymers with relative molecular weights ranging from thousands to 1 million, including Nonions, cations and anions, industrial grade, pharmaceutical grade and food grade. And it has been widely used because of its excellent and unique performance.
Density: 1.144g/cm3.
Boiling point: 217.6 °C.
Melting point: 130 °C.
Flash point: 93.9 °C.
Average molecular weight: 8000 to 700000.
Stability: stability at room temperature and pressure.
Solubility: soluble in water and halogenated hydrocarbon solvents, alcohols, amines, nitroalkanes and low molecular fatty acids, insoluble in acetone, ether, turpentine, aliphatic hydrocarbons and alicyclic hydrocarbons. It is compatible with most inorganic salts and many kinds of resins.
Properties: hydrophilic and easy to flow white or almost white powder, slightly smelly.
Crosslinked homopolymer of pure vinyl pyrrolidone. It has the ability of polyvinylpyrrolidone (PVP) to complexate with a variety of substances (such as various clairvoyants that cause discoloration of drinks such as wine). And because it is insoluble, it is easy to filter and remove.

1). Medical use:
PVP-K series can be used as tablet, granules of binder, injection of cosolvent, capsule flow aid.
2). Cosmetics industry use:
PVP-K series in the cosmetics industry are available to finish preparing, thickening agent, lubricant and binder, used to spray, moss, hair gel, hair fluid;In skin care products, hair dye, modifier, lipstick, shampoo, deodorant, sunscreen, toothpaste, etc.
3). Textile printing and dyeing industry use:
PVP-K series combined with different dye ability difference, can be used as a local stain agent and cleaner.In the process of blending PVP, make it uniform distribution in the fiber, can greatly reduce the fabric color difference after dyeing, improve the adhesion of the dye on the fabric.Get uniform color, light and heat is not easy to fade textile dyeing products, have the effect of leveling.PVP combined with different dye ability have a difference, make use of this nature, the polyamide fiber, polypropylene fiber dyeing printing proof, make local reserving agent PVP are available, and get pattern is bright, clear outline of printed fabric, stain effect.
