Description of calcium stearate

Molecular formula: Ca (C17H35COO)2   CAS No.: 1592-23-0

Calcium stearate is a kind of monomer soap; white powder, nontoxic, and insoluble in water. It’s mainly used as heat stabilizer in PVC processing and as lubricant, demoulding agent in various plastic processing.

The industry of calcium stearate is chaos due to the low technic requirement. Some factory’s quality is not good which will result in flaw products.

However, Winner’s calcium stearate has reliable quality. We adopted the international advanced technic, and produce them strictly according to the industry requirement. With three different quality grade, we can meet all the customers’ requirement.
1.    Advantages & Features of calcium stearate

A.    Excellence in long-term stability.

B.    Promote the melting and shorten the plasticization period.

C.    Good synergistic effect when used with zinc soap and epoxy compound.

D.    High up the gelation speed when used with zinc salt and zinc soap.

E.    Protect from the bad influence on color and stability caused by residue catalyst when used as PE’s and PP’s Halogen absorber.
