Calcium Stearate

White powder, insoluble in water, cold ethanol and ether, dissolved in hot benzene, benzene and turpentine and other organic solvents, slightly soluble in hot ethanol and ether. When heated to 400 ℃ slowly decomposed, flammable, in case of decomposition of stearic acid and corresponding calcium, hygroscopic.

Property:
Calcium stearate appearance of fine white, fluffy powder, creamy feel, soluble in water, toluene, ethanol and other organic solvents. Non-toxic, heated to 400 degrees Celsius slowly decomposed into stearic acid and corresponding calcium salt.
Applications:
1. used as a non-toxic PVC heat stabilizers, and has excellent lubricity. Thermal stability as effective as barium stearate, lead stearate, tin stearate and cadmium stearate. But cheap, low toxicity, good processing performance. Zinc soap and an epoxy compound with a synergistic effect, can improve the thermal stability. Commonly used in non-toxic food packaging films, medical devices and other requirements of soft products. And the base of lead and lead salts and soaps used for hard products, can increase the gelation speed. This product is used polyethylene and polypropylene, it can eliminate the adverse effects of residual catalyst on the resin color and stability.
