Lead Stearates are used in the manufacture of PVC Stabilisers. Calcium, Magnesium and Zinc Stearates are use in the processing and manufacture of polymers, paint and rubber.
Dibasic Lead Stearate (DBLS) is produced and supplied as a fine off-white powder, with a lead (Pb) content of 51.5%. DBLS finds its main use as a high temperature lubricant in PVC compounds. It also possesses good heat stabilising properties, particularly when used in conjunction with other lead stabilisers..
Normal Lead Stearate (NLS) is produced and supplied as a fine white powder, with a slightly greasy texture and a lead (Pb) content of 27%. NLS is used almost exclusively in the PVC industry. Whilst possessing some heat stabilising properties, it is used primarily as a lubricant in PVC compounding.
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:
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
Laq Grade
Wettable Grade
Magnesium Stearate is non-toxic and insoluble in water, low molecular weight alcohols, ester and ketones, but soluble in aromatic compounds. It is a fine white powder
Magnesium Stearate has a large number of industrial applications:
