Introduction
The main component of Kela Cerium Red cerium-based inorganic pigments is cerium sulfide. Cerium sulfide (Ce₂S₃) has a chemical composition approximating Ce₂S₃ and forms orthorhombic crystals. It is insoluble in water and strong alkaline solutions but readily dissolves in acids, releasing hydrogen sulfide gas. Under inert gas and reducing atmospheres, it maintains chemical stability up to 1500°C, while in oxidizing atmospheres it remains stable up to 350°C.

Product feature
Complies with EU hygiene regulations and meets the testing requirements of RoHS, the U.S. FDA, Germany’s BfR, and other standards. It is safe for products that come into contact with the human body and food, and it can also be widely used in engineering plastics and related industries. Color Range and Properties The Kela Cerium Red cerium-based inorganic pigment series covers a color spectrum from deep red to orange-yellow. Cerium Red is a soft crystalline phase material that does not damage the structure of glass fibers in plastics and can actually enhance the mechanical properties of glass fibers. Key Advantages Non-toxic: Safe for use and complies with EU export standards and related national safety, health, and environmental regulations Strong covering power: Excellent opacity and color strength Good thermal stability: Maintains performance at high temperatures Environmentally friendly: Serves as an excellent substitute for toxic cadmium sulfide-based or heavy metal-based inorganic pigments Cerium Red disperses readily in polymer systems, and its moderate particle size helps control dust generation. The pigment can withstand temperatures up to approximately 350°C in polymer systems, making it suitable for most industrial plastic applications. Key Performance Benefits: Environmental compliance: Meets RoHS and BfR standards with no toxic heavy metals Superior outdoor durability: Excellent UV protection and weather resistance Processing advantages: Easy dispersion with controlled particle size Thermal stability: High-temperature resistance suitable for industrial plastics Long-lasting performance: Maintains color integrity and extends material lifespan This combination of environmental safety, superior performance characteristics, and processing advantages makes Cerium Red an ideal choice for demanding applications requiring both environmental compliance and high-performance color solutions.
Application area
As a new type of green, environmentally friendly pigment, Cerium Red's high temperature resistance makes it widely applicable in: Nylon, engineering plastics, color masterbatch, pigment paste, Other applications requiring heat-resistant, non-toxic colorants This innovative pigment represents a significant advancement in replacing traditional toxic heavy metal pigments while maintaining superior performance characteristics and meeting stringent international safety standards.
