Masterbatches can reduce the pollution caused by the addition of powder in the production process, and make the production of color distribution or function to play a more uniform, so that the production of more efficient, lower additive costs, higher efficiency, lower environmental pollution. Divided into four categories: carbon black masterbatches (including general-purpose carbon black masterbatches and functional carbon black masterbatches), color masterbatches (including dazzling color masterbatches), functional masterbatches (including anti-static masterbatches, anti-ultraviolet masterbatches, fluorescent white masterbatches, smooth opening masterbatches), and antifoam masterbatches (black, grey, white).
