Shengzhu pigments are environmental-friendly pigments in conformance with FDA standards. They will not produce any hazard even if they directly contact human body. Therefore, they are applicable to plastic processing techniques, e.g. injection molding, blow molding, suction molding, casting, etc. or used for manufacture of cosmetic container, shampoo container, food and drug container, tube, daily plastic article, toy, button, sandals, home plastic ornament or PVC, PU calendaring leather, etc.
　Color changes of pigment are closely related to the dispersancy of pigments in plastics. Therefore, if high-transparency or semitransparent plastic reins are added with 0.6-1% Shengzhu pigments, an excellent pearl and metal luster effect will be obtained. Your multi-colored products will be more eye-catching. For low-transparency or nontransparent plastics, a pearlescent effect can still appear if they are added with Shengzhu pigments but the level of addition is one to two times larger.
