Pigments in Plastics Processing thermal stability index and concentration related to some pigments in different concentrations, the heat stability of pesticides vary greatly colorants such as CI Pigment Violet 23 is used for quality HDPE coloring pesticide colorant, a low concentration to 0.025% of the heat resistance of only 200 ℃, more than 0.1%, only 260 ℃. (2) a pigment in plastics processing and applications need thermal stability index material solution quality indicators related to pesticide colorant pigment guarantees thermal stability under certain application solution quality and a certain concentration, does not mean its other solutions quality indicators under par pesticide colorant companies, such as CI Pigment Violet 23 liquid coloring 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. Readily dispersible not only affects color strength and shade, but also because of poor dispersion uneven coloring, producing streaks or color point of impact colored appearance, more seriously affect the mechanical properties of the finished coloring. Pigment having good dispersibility can be an ideal brilliant degree, brightness, transparent plastic products, therefore, readily dispersible pigment for coloring plastics is important. Pigment used in chemical fiber spinning, which is easily dispersed more important to good or bad. In the melt spinning process due to stress how much, they have frequent replacement of filters, waste of materials and labor, so that equipment downtime is too long. More serious cause production can not be normal. Pesticide colorant | Weifang Fuyuan | Quality pesticide colorant provided by Environmental Science and Technology Co., Ltd. Weifang Fuyuan.
