LEAD STEARATE

Lead Stearate is a lead-based metallic soap formed by the reaction of lead salts with stearic acid. It appears as a fine, white powder with excellent thermal stability and lubricating properties. This compound is widely used as a heat stabilizer and lubricant in PVC processing and has applications in coatings, greases, and as a release agent in molding processes. Its multifunctionality makes it an essential additive in the plastics, rubber, and chemical industries.
