Due to the different phosphoric various resins, the chemical structure of the plastics triammonium colorant manufacturers, during the molding process require different heating temperatures (above the softening point), the temperature will directly affect the choice of colorant colorant tribasic ammonium , so the coloring does not occur at a predetermined temperature company significant color change colorant ammonium phosphate, different characteristics of the resin structure of the colorant requirements are not the same, Table 1 shows the plastic resin molding temperature and for a coloring agent Claim. Also some other resin processing temperature, respectively, fluororesin, 350 ℃; sales acrylic resin ammonium phosphate colorant, 180-200 ℃; silicone resin, 180 ℃; phenol resin, 150-160 ℃; Epoxy resin, 150 ℃; cellulosics 180 ℃ the like. Synthetic colorants mainly carotenoids. As β- apo -8- carrot aldehyde (C30H40O) or β- A - Park -8- carotenoid ester (C32H44O) and lemon yellow pigment (C33H44O), cantharidin, Gary red, Gary yellow, dew Kangding.
