Carbon black is able to control the curing reaction of polyester plastics

That is, the masterbatch can not participate in a variety of chemical reactions. Such as carbon black can control  ornamental gravel  reaction of polyester plastic , so you can not add carbon black pigment in the polyester .
Due to the high temperature plastic molding process , so should not break down color pigment in molding the heating temperature conditions. General inorganic pigments good heat resistance , poor heat resistance of organic pigments and dyes , this should be taken seriously enough variety in the choice of pigment .Dispersion of the pigment should be a good  photoluminescent pigment suppliers  . When pigment dispersed unevenly , it will affect the appearance of the performance of products ; pigment tinting strength is poor, will increase the amount of pigment material costs increased. The same pigment dispersion in various resins and color strength are not the same , so pay attention when choosing this pigment .
