Calcium stearate is soluble in toluene, alcohol, benzene and other organic solvents, insoluble in water, and slowly decompose when be heated to 400 degrees, combustible, decompose into stearic acid and calcium salts when in acid, water absorption, nontoxic. Calcium stearate is a PVC stabilizer and lubricant, nontoxic, no pollutants, long-term thermal stability.
Calcium stearate is used as waterproofing agent, lubricant and plastic additives. Widely used in food, pharmaceuticals, cosmetics, plastics and rubber industries, mainly for lubricants, emulsifiers, stabilizers, mold release agent, promoter, makeup base, etc. In rigid plastic condensate velocity can be improved. It can also be used for food packaging, medical equipment and other drug-free films, with stabilizer effect, long term stability is good. As PVC stabilizer and lubricant in polyethylene, as halogen absorbent in polyethylene and polypropylene, it can remove the catalyst for residue of the resin in the resin color stability and adverse effects. It also is used to improve heat resistance of plastic and weatherability of coloring and breathability in the early, will replace toxic stabilizer with the same performance.
Calcium stearate is PVC heat stabilizers and lubricants, mold release agent in process of various kinds of plastics. In rigid products, combined with lead based salts, lead SOAP, it can enhance the speed of coagulation. As a plasticizer in rubber processing, thickening agent of grease, waterproof agent of textiles, flatting agent of paint, plasticizer of manufacturing plastic record. Also used in pencil lead production, pharmaceuticals and the perfume industry.
