Kela Material presents Cerium Orange - One of the Cerium-Based Inorganic Pigment Series
The main component of Kela 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.
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
Applications
As a new type of green, environmentally friendly pigment, Cerium Red's high temperature resistance makes it widely applicable in:
Plastics industry
Rubber industry
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.
What is Cerium Sulfide Orange (PO755P)?
Cerium Sulfide Orange (PO755P) is an inorganic orange pigment based on cerium sulfide technology.
It is designed to replace traditional toxic heavy-metal orange pigments while maintaining strong
color strength and durability.
Is PO755P free of cadmium and other toxic heavy metals?
Yes. PO755P is cadmium-free and contains no lead, chromium(VI) or other commonly regulated toxic
heavy metals, making it suitable for use in applications that must meet strict environmental and
safety regulations.
Where is PO755P typically used?
PO755P is mainly used in plastics and rubber, including PP, PE, PVC, ABS and engineering plastics,
as well as masterbatches and color compounds that require a clean, durable orange shade.
How does PO755P perform under processing temperatures?
PO755P offers good heat stability under typical plastics processing and masterbatch extrusion
conditions and is suitable for most conventional processing temperatures used in plastics
and rubber applications.
Environmental Protection
Kela Cerium Orange cerium-based inorganic pigments have passed RoHS certification and BfR's stringent testing requirements. They contain no restricted or prohibited heavy metals or organic pollutants, making them environmentally friendly inorganic pigments.
Excellent UV and Light Aging Resistance
Cerium Red exhibits exceptional brightness and outstanding UV resistance and far-infrared reflection capabilities. It also demonstrates excellent weatherability and light fastness, enabling surfaces to maintain long-lasting color and extending the service life of plastics. This makes it an excellent outdoor colorant.
Easy Dispersion and High Temperature Resistance
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.
