In order to overcome the drawbacks dye coloring, improve the quality of plastic products, with the continuous development of the plastics industry, innovative types of plastic resins, additives types of plastics processing equipment and technology, a breakthrough, another way plastics coloring - - colored masterbatch has been widely adopted, colored masterbatch technology application and practice are continuously improved. The so-called masterbatch, which uses some kind of process and corresponding equipment, in the role of aid, the pigment (or dye) into the carrier, the price of pesticides colorant by heating, plasticizing, mixing, shearing, eventually molecule molecular pigment powder and carrier resin fully combined sales of pesticides colorant, and then made with the resin particles of similar size particles.
