What is high-temperature pigment?

Yabang organic pigments are used for plastic coloring. In addition to their inherent coloring properties, they should also have dispersibility, heat resistance, and migration resistance that meet the requirements of plastic coloring processing technology. The colored products should have weather resistance, optical rotation resistance, solvent resistance, and meet the requirements of food hygiene standards in the use environment.

Traditional classic azo organic pigments have been widely used in the coloring of plastic products due to their uniform color spectrum, bright color, and reasonable price. However, due to their chemical structure and other factors, there are various defects in heat resistance, optical rotation resistance, migration resistance, etc., especially in light colored coloring, the gap is even greater. In addition, traditional benzidine yellow and orange series pigments undergo thermal decomposition when used in polymer processing at temperatures exceeding 200 ℃, resulting in monoazo compounds and aromatic amines. When the temperature exceeds 240 ℃, dichlorobenzidine will also be produced. The impact of pigment decomposition products on the human body and environment is increasingly attracting people's attention. In today's increasingly competitive market, the appearance and performance of products have never had the same impact on consumers' purchasing desire, especially in the fields of automobiles, household appliances, daily consumer goods, and other markets. In order to meet the needs of consumers, countries around the world are focusing on developing high-performance organic pigments for plastic coloring.

High Performance Organic Pigments (HPP) mainly include the following categories: Quinacridone, Bisazone, Isoindolinone, Pyrrolopyrrolidone (DPP), Anthraquinone Heterocycles, Benzimidazolone, Condensed Azo, etc
