DESCRIPTION
Tribasic Lead Sulphate (TBLS) is produced and supplied as a fine white powder. It has a lead (Pb) content of 83.5%. It can be heated to high temperatures without decomposition.
Its method of manufacture ensures that there is the minimum amount of free electrolytes present in the product. The product is packed in either 25kg multi-ply paper sacks or in 1000kg bulk bags.
TYPICAL APPLICATIONS
Good flow properties and ease of dispersion of TBLS are of considerable advantage in the preparation of PVC compounds. Due to its excellent thermal stability, it is particularly suitable for stabilising PVC which is to be processed at high temperatures or speeds. Rigid PVC compound that is used for injection moulding of various products, can be stabilised with TBLS. The fine particle size and absence of free electrolyte ensures that when TBLS is used to stabilise PVC cable sheathing compound, it does not cause a deterioration in electrical properties of the cable. TBLS is not a lubricating stabiliser and PVC compounds containing it normally require the addition of 0.5 - 1.5 phr of lubricant (such as DBLS and NLS).
