Calcium stearate nature

Calcium stearate uniform fine white powder. Melting point 175 ℃, density 1.035g/cm3. Dissolved in toluene , ethanol, benzene and other organic solvents , insoluble in water . Slowly fluorescent brightener  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 food packaging, medical equipment and other requirements nontoxic soft film and equipment. Can be made of polyethylene , polypropylene, halogen absorbent to PVC window stabilizer  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 manufacturing plastic LP plasticizers. Also used in pencil manufacturing and pharmaceutical , perfume industry .
Action
Polyolefins polyolefin acid neutralizer and  blowing agent 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 polyurethane foam
Unsaturated polyester
