Product Description

Tri Basic Lead Sulphate is the most popular and versatile lead stabilizer for P.V.C., especially for high temperature working. It is in itself very stable to heat and can be heated without decomposition to temperature well in excess of those normally encountered in compounding and fabricating P.V.C. such as high speed extrusion or manufacture of rigid products. In the absence of any decomposition, it ensures sound products with complete absence of porosity caused by evolution of gases. Very good electrical properties are also feature of compounds stabilized with Tri Basic Lead Sulphate.

Tri Basic Lead Sulphate has excellent stabilizing properties in P.V.C. It is suitable for all pigmented compounds where long period heat stability is required especially for rigid or unplasticized extrusion of rain water goods, guttering, soil pipes for conveyance of gases and liquids.

Besides, a mixture of Tri Basic Lead Sulphate and Di Basic Lead Phosphite has been found in practice to have excellent weathering properties; the Di Basic Lead Phosphite having excellent resistance to ultraviolet light.

Because of its good electrical properties, it is widely used for cable sheathing purpose. When used with suitable electrical grade polymer, high values of volume and surface resistivity can be maintained.
