calcium stearate. CAS NO.1592-23-0

White powder, insoluble in water, soluble in hot ethanol, ether and other dissolved organic solvent heating, cooling, then through into jelly.In strong acid decomposition, density 1.323 g/cm 3.Melting point: 130-150 ℃, with water in the air.

Used as a non-toxic heat stabilizer of PVC, and has good lubricity.Effect of thermal stability than barium stearate, lead stearate, stearic acid tin and cadmium stearate.But cheap, small toxicity, good processing performance.With zinc soap and epoxy compound and has synergistic effect, can improve the thermal stability.Often used in food packaging film, medical instruments and non-toxic soft products.With basicity lead lead salt and soap and used in hard ware, gelation speed can be improved.This product is used for polyethylene and polypropylene, can eliminate residual catalyst for the bad influence of resin color and stability.This product is widely used for polyolefine, polyester reinforced plastics, the lubricant of phenolic resin, amino resin, thermosetting plastic and mold release agent.This disadvantage is that the initial coloration, above 100 ℃ heating time is longer, can make the white PVC plastic into a reddish, particularly in the formula in the presence of titanium dioxide, shading is particularly acute.This product use, there are segregation phenomenon of fouling.2. During the oilfield operations used as lubricating agent solution card.Also used as PVC thermal stabilizer and a variety of plastics processing lubricants, release agents, etc.In the hard ware, cooperate with basicity lead lead salts, soap gelation speed can be improved.Also used in food packaging, medical equipment and other requirements of non-toxic soft film and apparatus.Still can be polyethylene, polypropylene absorbent halogen, to eliminate the residual catalyst on the stability of color and bad influence.As a plasticizer in rubber processing, can make the natural rubber and synthetic rubber to soften and almost no effect for curing.Also used as thickening agent in lubricating grease, textiles, waterproofing agent, smoothing agent paint, manufacturing plastic record at the time of the plasticizer, etc.3. The calcium stearate is a non-toxic heat stabilizer and lubricant, is also flat of adhesive, coating agent and water resistance, in plastic and rubber, etc. Widely used in the process of chemical production.Effect of thermal stability than barium stearate, lead stearate, stearic acid tin and cadmium stearate.But cheap, small toxicity, good processing performance.With zinc soap and epoxy compound and has synergistic effect, can improve the thermal stability.Often used in food packaging film, medical instruments and non-toxic soft products.Also widely used for polyolefine, polyester reinforced plastics, the lubricant of phenolic resin, amino resin, thermosetting plastic and mold release agent.4. Used for powder in cosmetics.Add in the powder, the powder adhesion, good lubricity, spread out evenly and formability of powder.
