Polyvinylpyrrolidone, additionally recognised as PVP, is a polymer of ethylene pyrrolidone. Due to its one-of-a-kind 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 with the aid of reacting with polyphenols. By the use of this method, there are without problems 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.
