Calcium stearate soluble in toluene, ethanol, benzene and other organic solvents, insoluble in water, heating to 400℃ slowly decomposition, flammable, in case of strong acid decomposition into stearic acid and the corresponding calcium salt, water absorption, non-toxic. Calcium stearate is PVC stabilizer and lubricant, non - toxic, non - sulfur pollution, long - term thermal stability.

Calcium stearate is used as water-proofing agent, lubricant and plastic assistant. Widely used in food, medicine, cosmetics, plastic and rubber industries, mainly as lubricants, emulsifiers, stabilizers, mold release agents, promoters, cosmetics base materials. In hard plastic products can improve the coagulation rate. It can also be used as non-toxic soft film for food packaging and medical appliances. In polyethylene, polyvinyl chloride stabilizer and lubricant, in polyethylene and polypropylene as halogen absorbent, can eliminate the residual catalyst in the resin on the color and stability of the resin. Widely used in foreign countries to improve the heat resistance of plastics, improve the weather resistance of initial coloring and air permeability, will replace the same performance of toxic stabilizer.

Calcium stearate as PVC heat stabilizer and a variety of plastics processing lubricant, mold release agent. In hard products, the combination with base lead salt and lead soap can increase the coagulation rate. As plasticizer in rubber processing, thickening agent of grease, waterproof agent of textiles, flat agent of paint, plasticizer for making plastic records, etc. Also used in pencil lead production and medicine, spice industry.
