Type of plastic colorant type of plastic colorant, its physical form is divided into four categories: powdered colorants - Toner; colorant paste - paste; liquid colorant; solid state colorant - masterbatch. Which is widely used as a solid powdered colorants and colorants. Therefore, for the other two kinds of coloring agents are not discussed herein. Use colored toner, since the required uniform distribution of the pigment powder colored resin, it is better dispersibility, colorants pesticide products, the only conclusion for injection products, in particular thick-walled products, pesticides colorant, For blown film, spinning products is another matter. Because the toner is generally not been pretreated, when it is mixed with the resin, the credibility of the pesticide colorant, alone from the extruder feed port, a screw, to the discharge port so so short a distance as well as mixed plastics time, to make pigment powder pigment molecules and colored molecules join hands well - fully integrated, completely can not guarantee there will be "cooked" phenomenon. However, this "cooked" phenomenon in the thick product will be masked out, blown film, spinning products is obvious. So which method is still colored masterbatch based.
