Dibasic Lead Stearate (DBLS)

Dibasic Lead Stearate (DBLS) is produced and supplied as a fine off-white powder, with a lead (Pb) content of 51.5%. The product is packed in either 25kg multi-ply paper sacks or in 1000kg bulk bags.

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.

Tribasic Lead Sulphate is universally accepted as an excellent heat stabilizer for PVC processing involving high temperatures and performance in rigid extrusion, electrical insulation, calendering and spreading. It gives excellent weather resistance when used for outdoor water pipes, conduits, rain water down pipes, drainage pipes and profiles used in building industry.

Lead Stearate

White micro-crystal powder, combustible, specific density 1.323, insoluble in water, slightly soluble in ethanol and ethyl oxide. It becomes gray-black when heated and dissolved, and decompose and becomes steric acid and corresponding salt under strong acid condition.

The product is a high efficient stabilizer and lubricant processed under low temperature condition. The product has good stability to ray and rejection performance to original coloration. So, it is mainly used for extrusion and injection of hard PVC products.

Zinc stearate (Zn(C18H35O2)2) is a zinc soap that repels water. It is insoluble in polar solvents such as alcohol and ether but soluble in aromatic hydrocarbons, e.g. benzene and chlorinated hydrocarbons when heated. It is the most powerful mold release agent among all metal soaps. It contains no electrolyte and has a hydrophobic effect.

Its main application areas are the plastics and rubber industry where it is used as a releasing agent and lubricant which can be easily incorporated.

Calcium stearate

Calcium stearate is a non-toxic stabilizer and lubricant with the molecular formula Ca(C18H35O2)2. It is an insoluble calcium salt of stearic acid. Commercially it is sold as a 50% dispersion in water or as a spray dried powder. As a food additive it is known by the E number E572.
