Cadmium Stearate
Cadmium stearate is a white to off-white, hydrophobic powder known for excellent heat stability, lubrication, and light stability. It functions as a lubricant, release agent, and heat stabilizer in PVC, plastics, and specialty polymer applications. Chemically, it is the cadmium salt of stearic acid, insoluble in water but soluble in hot organic solvents, and decomposes in strong acids to release stearic acid. Cadmium stearate improves product clarity, surface smoothness, flow, and processing efficiency; however, due to the toxic nature of cadmium compounds, it must be handled with strict safety controls.
At Evergreen Chemical Company Thailand, we supply high quality Cadmium stearate powder formulated to meet international standards. With decades of experience in the specialty of chemicals, Evergreen is known for delivering consistent, reliable, and application specific products. Our in house quality control and testing protocols ensure every batch meets strict purity, performance, and safety criteria making us a trusted partner for manufacturers across Asia and beyond.

Cadmium Stearate Safety
Cadmium stearate is used in industrial applications such as PVC stabilization and polymer processing under strictly controlled conditions and in compliance with applicable regulations. It delivers excellent heat stability and processing performance; however, due to the toxicity of cadmium-based compounds, rigorous safety measures are essential. The use of appropriate personal protective equipment (PPE), effective ventilation, controlled handling procedures, and proper storage in a dry, well-ventilated environment are required to minimize exposure and ensure safe use in industrial manufacturing processes.
