I am Otto, learning about pigments. As a benchmark in the pigment industry, Lanxess has always been in a leading position. Today, I will learn about the application of Lanxess Colortherm® Chromium oxide green series in plastics. If there are any errors, please help me correct them.
Chromium oxide green (Cr₂O₃), an inorganic pigment with high thermal stability and chemical resistance, is widely used in plastics for demanding applications. Key features and uses include: Heat Resistance: Withstands temperatures up to 400°C during processing (e.g., injection molding). UV/Weather Resistance: Protects outdoor plastics (e.g., garden furniture) from fading and warping. Chemical Inertness: Resists acids, alkalis, and solvents, ideal for automotive and industrial parts. High Opacity: Achieves vibrant colors with low pigment concentration, reducing costs.
Chromium oxide green is mainly used in high-temperature plastics: for automotive engine compartment components (such as connectors, housings). For outdoor products: Enhance the durability of packaging, amusement facilities, and roofing materials. Functional additive: As a flame retardant for electrical insulation, it slightly improves wear resistance.
Compared with organic pigments, it has excellent stability: superior to phthalocyanine green in terms of heat resistance, UV resistance, and chemical resistance.
