Some of the major properties of calcium stearate

Calcium stearate, calcium stearate uniform nature of fine white powder. Melting point 175 ℃, density 1.035g/cm3. Dissolved in toluene , ethanol, benzene and other organic solvents , insoluble fluorescent brightener  in water . Slowly heated to 400 ℃, decomposition, combustible , the case of decomposition of stearic acid and corresponding calcium salts . Water absorption, non-toxic.
Use heat stabilizers for PVC and a variety of plastics processing lubricant , release agent . In rigid products , and the base of lead salts , lead soap can increase the gelation speed. Also used in  Impact modifier for PVC food packaging, medical equipment and other requirements nontoxic soft film and equipment. Can be made of polyethylene , polypropylene, halogen absorbent to remove the residual catalyst on the adverse effects of color and stability . As a plasticizer in rubber processing , make the whole into a natural rubber and rubber softening , and almost no effect on curing . Also used as a molding of polyolefin fibers and lubricants , grease thickening agent, textile waterproofing agent, paint flatting agent , when  whitening agent manufacturing plastic LP plasticizers. Also used in pencil manufacturing and pharmaceutical , perfume industry . Polyolefins polyolefin acid neutralizer and corrosion stability of the color is directly offered ; lubricating / processing aids improve the polyolefins, polyamides , styrene and rubber in the extrusion molding ( film, fiber , copying , etc. ) , and press molding processability. Release properties of the thermoplastic plastics , rubber, and thermoset articles, such as unsaturated polyester polyurethane foam
