Cerium Stearate
Cerium stearate is a rare earth metal salt of stearic acid, produced by reacting stearic acid with cerium compounds. It appears as a fine white to off-white powder and is highly hydrophobic and insoluble in water. Combining long-chain fatty acids with cerium ions, cerium stearate exhibits excellent thermal stability, oxidation resistance, and lubrication properties.
These unique characteristics make cerium stearate particularly suitable for high-temperature, high-performance industrial applications, including plastics, rubber, specialty coatings, lubricants, and advanced material formulations.
At Evergreen Chemical Company Thailand, we supply premium-grade cerium stearate powder developed for demanding industrial environments. Manufactured under strict quality control systems and compliant with international standards such as ISO and REACH, our cerium stearate ensures consistent performance, purity, and batch-to-batch reliability.

Cerium Stearate Properties and Features
1. Thermal & Oxidation Stabilizer
Cerium stearate functions as an effective thermal and oxidation stabilizer, particularly in polymer and rubber systems exposed to high processing temperatures. It helps reduce oxidative degradation, extending product lifespan and maintaining material integrity.
2. Lubricant & Processing Aid
As a metal soap, cerium stearate provides excellent lubrication during extrusion, molding, and compounding processes. It reduces internal friction, improves flow characteristics, and enhances surface finish of finished products.
3. High-Temperature Resistance
Cerium stearate offers superior heat resistance compared to conventional metal stearates, making it suitable for specialty plastics, elastomers, and industrial lubricants operating under elevated temperatures.
4. Hydrophobic & Water-Repellent Properties
Due to its hydrophobic structure, cerium stearate improves moisture resistance in coatings, polymers, and industrial formulations, contributing to improved durability and stability.
5. Anti-Sticking & Release Performance
Cerium stearate acts as an effective release agent, preventing adhesion to molds and processing equipment and enabling smoother, more efficient manufacturing cycles.
Cerium Stearate Applications
Cerium Stearate is primarily utilized in Plastic Additives applications, where it serves as a stabilizer, lubricant, and processing aid to enhance thermal stability, oxidation resistance, and overall processing performance in specialty plastics, polymers, rubber, coatings, industrial lubricants, and advanced material systems.
1. Plastics & Polymer Industry
Cerium stearate is used as a stabilizer, lubricant, and processing aid in specialty plastics and engineering polymers. It improves thermal stability, processing efficiency, and surface quality of finished products.
2. Rubber & Elastomers
In rubber compounding, cerium stearate enhances heat resistance, reduces oxidative aging, and improves processability during mixing and molding operations.
3. Coatings, Paints & Inks
Cerium stearate functions as a rheology modifier and hydrophobic additive in coatings and inks. It helps prevent pigment settling, improves dispersion stability, and enhances water resistance.
4. Industrial Lubricants & Greases
Due to its thermal and oxidation stability, cerium stearate is used in specialty greases and lubricants designed for high-temperature and high-load applications.
5. Advanced & Specialty Materials
Cerium stearate is also utilized in advanced material systems where rare earth additives are required to enhance thermal performance, oxidative stability, or processing behavior.
