Kind of difficulty with the polymer and other additives, organic pigments migration (especially plasticizers and softeners) have a great relationship. Experiments show sales tribasic ammonium colorant, in general, organic acid salts mobility is relatively small; the higher molecular weight is smaller than the lower mobility. Heat resistance. Excellent heat stability as an important indicator of plastic colorants, most inorganic pigments are better heat resistance, and can basically meet the requirements of plastic processing ammonium phosphate colorant companies, and poor heat resistance of the organic colorant . You can choose suitable colorants according to different temperatures. Chemical stability. Due to the use of different plastics environment, so to take full account of chemical resistance colorant ammonium phosphate colorants, such as PVC and other chlorine-containing polymeric easily decomposed to produce hydrogen chloride, coloring effect colorant and color fastness may produce more big impact, so PVC and other chlorine-containing polymer products must use acid colorant; as certain plastics parts other additive such as antioxidants, hindered amine light stabilizer, dispersant on the pigment can not be ignored . Ammonium phosphate company colorant colorants ammonium phosphate _ _ Weifang Weifang Fuyuan Fuyuan provided by the Environmental Protection Technology Co., Ltd.
