Calcium Stearate

Calcium Stearate
Calcium stearate uses the international advanced dry production process (high-speed dispersion direct neutral method), the production process energy-saving pollution-free, high purity products, low free acid value, good lubrication.

Calcium stearate is kind of fine white powder with greasy touch sense, soluble in hot water, methylbenzene, ethanol and other organic solvents, innoxious, slowly decomposes into stearic acid and calcium salts when it is heated to 400°C. As Calcium stearate suppliers, we will provide the best quality to everyone

Product name: Calcium stearate
Appearance: White micro powder
Application: AS PVC additive, PVC stabilizer adding in PVC products
MF: Ca(C17H35COO)2
MW: 606
Certification: ISO9001, SGS


1, For PVC hard products: used as stabilizer and lubricant agent, it can improve the gelation speed with the basic lead salt and lead soap.

2, For polyethylene and polypropylene: used as halogen absorbing agent, it can eliminate the bad effect of residual catalyst to the resins color and stabilizer in the resins.

3, For polyolefin fiber and plastic model products: used as lubricant and mold-releasing agent.

4, For rubber processing: used as mold-releasing and plasticizer agent, intensifier for lubricating grease,water-proof agent for textiles, flatting agent for paint chemical industry,etc.

5, Also can be used in food additive, feed additive and cosmetics.
