Pratham Stearchem Di Basic Lead Stearate is a white powder which finds extensive use in the field of lubricant and stabilizer at high temperatures during PVC processing. This is because Di Basic Lead Stearate has free lead oxide and free fatty acid content. The free lead oxide contributes towards the stability, whereas the free fatty acid helps in lubrication, both working well at high temperatures. Di Basic Lead Stearate finds application in cable manufacturing, PVC processing, calandering operations and extrusions. Due to toxicity, Di Basic Lead Stearate is not used in articles that are likely to come in contact with foodstuff. Normally, Di Basic Lead Stearate is used along with Lead Stearate and Tri Basic Lead Sulfate.
