Tribasic Lead Sulphate is universally accepted as an excellent 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.
Because of its high electrical resistance property, it is extensively used in wire and cable industry. It is used along with Lead Stearate and Dibasic Lead Stearate to obtain optimum lubricating properties and desired finish to the end product. It is also used in combination with other lead stabilizers like Dibasic Lead Phoshite for achieving better light and heat stability for specific applications. It is also used as stabilizer in extruded, calandered & moulded PVC products.
