Pigments in Plastics Processing thermal stability index and concentration related to some pigments in different concentrations, the heat stability vary widely, such as CI Pigment Violet 23 for HDPE coloring concentration is less than 0.025%, the heat resistance of only 200 ℃, more than 0.1%, only 260 ℃. (2) thermal stability index pigment material solution quality and application needs are related pigment in plastics processing thermal stability index at a certain application solution quality and a certain concentration, it does not mean their targets in other solutions of comparable quality , 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 concentration in the plastics processing heat index of titanium dioxide colorant for general pesticide manufacturers, titanium dioxide was 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 occurs when the colored resin thermal stability of the resin is heated itself as yellowing discoloration of pesticide colorant companies, which Heat Index will also affect the paint application in the plastic. Major organic pigments carbon black, azo pigments, phthalocyanine, quinoline ketone, isoindolinone, anthraquinone, thioindigo pigments and various chemical, wherein the carbon black is the most common use of the black pigment, it has a price Lim color fastness, dispersion, and the advantages of good flowability of the plastic while it's still impart electrical conductivity and UV degradation filling good climate and so on. Ideal colorants may make many demands, such as want it colorful, coloring force, easily dispersed without being aggregated in plastics, high heat resistance, but has no effect on the flow of plastic, does not affect the resin's resistance to aging and Its other performance, weather Fast and cheap, non-toxic, and so on. Which pesticide colorant cheap, Weifang Fuyuan (online consultation), pesticide colorant provided by Environmental Science and Technology Co., Ltd. Weifang Fuyuan. Weifang Fuyuan Environmental Technology Limited (www.wfdafuyuan.com) (www.wfdafuyuan.com) Shandong Weifang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer demand. In Weifang Fuyuan leadership with the staff warmly welcome all inquiries negotiations to create Weifang Fuyuan better future.
