Application:

PVP application in daily used chemical product  In daily used beauties PVP has best dispersivity and film forming characters, it can be used as case-hardened liquid, hair spray, case-hardened agent of mousse, opacifying agent of Hair conditioner, foam stabilizer and wave case-hardened agent of shampoo, dispersant and affinity agent of tint. Adding PVP in vanishing cream, sunproof cream and depilation agent can increase the wettish and lubricative effect. In addition, adding PVP in detergent can prevent annesl and increase the wash capability.


PVP application in industry and high-tech domain: PVP in dyestuff, paint ink, fiber dye and color kinescope can use as surface cladding agent, dispersant, thickening agent and bond. PVP can improve on the bond ability to metal, glass, plastic and so on. Otherwise, PVP are widely used in separation film, light  cured composite resin, paint, coatings, optical fiber, laser video disk and many other high-tech domain.
