Calcium, Magnesium and Zinc Stearates

Calcium, Magnesium and Zinc Stearates are use in the processing and manufacture of polymers, paint and rubber.

Calcium Stearate

Calcium Stearate is produced and supplied as a fine white powder. It is completely insoluble in water, low molecular weight alcohols, esters and ketones, and only slightly soluble in aromatic compounds. It is known to be completely non-toxic.

Calcium Stearate has a large number of industrial applications

As a lubricant in PVC compounds, and as a stabiliser in conjunction with other metallic soaps
As a lubricant in the production and processing of polyolefins
In the paper coating industry
As a mould release agent
As an anti-caking agent

Zinc Stearate

Zinc Stearate is produced and supplied in a number of grades – Ordinary, Laq and Wettable. It is a fine white powder that is completely insoluble in water, low molecular weight alcohols, esters and ketones, and is only slightly soluble in aromatic substances. It is known to be completely non-toxic.

Zinc Stearate has a large number of industrial applications

Ordinary Grade

As a non-toxic stabiliser in PVC, usually in conjunction with Calcium Stearate
As a lubricant in the production and processing of polyolefins
