TBLS(Tri-Basic Lead Sulphate)
Shivkrupa Industries has grown to become one of India’s leading TBLS manufacturers. Tri Basic Lead Sulphate, abbreviated as TBLS, is a white powdered substance. It has a low molecular weight and is very wet. It contains between 87 and 89 percent lead. TriBasic Lead Sulphate is usually used in combination with a lubricant such as Calcium Stearate or DBLS.
The most common and flexible lead-based heat stabilizer for PVC is TriBasic Lead Sulphate. Shivkrupa Industries offers TriBasic Lead Sulphate a very uniform particle size and uniform distribution, leading to good distribution in the PVC matrix and hence enhanced heat stability, shine, and output.
In PVC, TriBasic Lead Sulphate possesses exceptional stabilizing qualities. The unique surface coating improves the efficiency of lower concentrations, allowing PVC compounds and products to be made with lower stabilizers and indeed at a reduced cost.
