(Total 24 Products for PVP K30 USP24)
Polyvinylpyrrolidone, additionally acknowledged as PVP, is a polymer of ethylene pyrrolidone. Due to its unique ranges of polymerization, it can be divided into soluble PVP and insoluble PVPP (polyvinylpyrrolidone). The relative molecular weight of soluble PVP is 8000~10000, which can be used as a precipitant to precipitate by way of reacting with polyphenols. By the usage of this method, there are effortlessly residual PVP in the wine.

The conductivity of carbon black is carefully associated to its shape (especially graphite microcrystalline structure), floor properties, and particle size. The conductive mechanism of carbon black in rubber often consists of conductive channel and Field electron emission mechanism. The conductive channel mechanism is that carbon black aggregates come into contact with every different in the adhesive to structure a community like channel and behavior electricity.
