Polyvinylpyrrolidone - Eastar Holding Group Co.,Ltd.

Polyvinylpyrrolidone (PVP) to some is thought of as being a "miracle" polymer because it has so many almost amazing applications. In filtration science, it is known most widely as a treatment for membrane filters to make them more wettable to enhance filtration kinetics. In the microscopy and histology laboratory it is also used as an osmotic adjustor for certain resin systems such as LR Gold. To those working in the cosmetics and toiletries industry, PVP is often times the polymer that gives a hair spray product it desired characteristics, the polymer has a tendency not only to want to coat the hair, but it also tends to be attracted to keratin, and when rinsed, it tends to want to "stick" to the hair. Since it does exhibit some mount of conductivity, when hair is combed, the static charge is carried away, and especially those with long hair don't have as great of a tendency to get the "frizzies". However, don't try to make your own conditioning shampoos with the SPI-Chem PVP because what is used in the cosmetics industry is a hydrolyzed form of PVP.

And these characteristics sometimes also have application in electro static discharge (ESD) control since a surface can be easily treated (by dipping into an aqueous solution of the polymer) and rendered at least to some degree, surface conductive. UV curing the treated surface tends to make it even more wetable but some times the electrical conductivity properties are reduced (as reported to us by those who have used PVP).

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, lightcured composite resin, paint, coatings, optical fiber, laser video disk and many other high-tech domain.

Polyvidone is widely used in pharmaceutical area is one of the first three new supplementary materials by international sparkplug. The most widely used area is as bond in troche or pelletized granule. PVP can also use as glidant of capsule, the detoxication agent and lubricant of eyedrop, the cosolvent of injection, the dispersant of liquid preparation and the stabilizer of enzyme and temperature sensing drugs. Polyvidone can compose PVP-I antiseptic with iodine. PVP uses as low temperature conservant in pharmaceutical area. Tens of Drugs use PVP as supplementary materials.
