Tri Basic Lead Sulphate (TBLS)

Tri Basic Lead Sulphate (TBLS) by Pratham Metchem is tri basic lead stearate. It acts as a heat stabilizer at high temperatures during rigid PVC processing. Appears as a white powder and lacks lubricating property, hence it is usually used along with a lubricating substance, mostly calcium stearate or DBLS. Its applications include manufacturing of cables and extrusions and calendaring operations. Tri Basic Lead Sulphate (TBLS) is also used in extruded, calendered & molded PVC products but cannot be used in articles that are likely to come in contact with foodstuff.
