Product Description

Calcium Stearate
Molecular formula: C₁₇H₃₅ (COO)₂ Ca

Property: It is fine white nontoxic and no curing pollution with specific gravity 1.08. It can slightly dissolve in hot ethanol, but not in water.It will be decomposed to stearate or sale when meet strong acid and can absorb moisture in air. Much attention shall be paid during storage and transportation.

Application: It has good thermal stability, but poorer than lead stearate ans barium stearate. It is better if used with zinc or epoxy compound, so it is widely used for the nontoxic products. PVC can become light red at 160 ºC or heated for a long time. If in a large quantity, there will be frost phenomenon.
