Pigments in Plastics Processing thermal stability index and concentration related to some pigments in different concentrations of pesticide colorant product, its thermal stability vary widely, such as CI Pigment Violet 23 for HDPE coloring concentration is less than 0.025 % heat resistance is only 200 ℃, the price of pesticides colorant, more than 0.1%, only 260 ℃. (2) a pigment in plastics processing applications need thermal stability index and related material solution quality paint application solutions at a certain quality and a certain concentration of heat stability index, pesticide colorant, does not mean its other substance in solution Indicators under par, for example, CI Pigment Violet 23 solution colored polyester capability at 260 ℃ / 4 h. Therefore, be careful to choose the test after the pigment in these usage. (4) adding the pigment in plastics processing and titanium dioxide concentration of heat-related indicators in general, titanium dioxide is added after the heat index will decline. (5) was added to a concentration of colored resin itself heat index of titanium dioxide related (5) due to thermal degradation and discoloration such as yellowing when colored resin thermal stability of the resin is heated itself, this will also affect pigment Application of the heat index in the plastic. 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 of the colorant, such as PVC and other chlorine-containing polymeric easily decomposed to produce hydrogen chloride, may have a greater impact on the coloring effect of colorants and color fastness, and therefore PVC and other chlorine-containing polymer products must use acid colorant; as certain plastics components of other additives such as antioxidants, hindered amine light stabilizer, dispersant on the pigment can not be ignored.
