Applications :
1. Cosmetics: By virtue of its disperse and film-forming, PVP-K series can be used as the key components of hair sprays, mousse, gels and lotions & solution, hair-drying reagent and shampoo in hair-care products. They can also enhance the moisture and lubricant effect with some in skin-care products and depilatory. In addition, they are helpful in prevent color changes and enhance the cleanness with PVP in washing reagent.
2. Industry and High Tech Area: PVP can be used as covering, dispersing, viscosity-enhancement reagent and bond in paint, printing ink, textile, dyeing and color tube. They can also improve the adhesive capability to Metal, Glass and plastic materials. Besides they are widely used in film-separating, medical macromolecule, resin, paint, ray-guiding fiber and laser video, etc.

Packing: 25kg cardboard drum with polyethylene lining, Solution, in bulk tank-wagons or IBC container.

Applications : PVP is one of the three new and excellent pharmaceutical excipients. They are mainly used as binder for tablet, dissolving assistant for injection, flow assistant for capsule, dispersant for liquid medicine, stabilizer for enzyme and heat sensitive drug, lubricator and antitoxic assistant for eye drug; PVP and iodine may compound PVP-I and be used as antitoxic and bactericidal assistant; They can also enhance the hydrophilicity as the component of contact lens; Besides PVP can also be used as a low temperature keeping assistant.
