Description

Lead Phthalate (Dibasic) is an organolead compound primarily used as a heat stabilizer and lubricant in polymer formulations. This product is valued for its ability to enhance the thermal processing stability of materials, particularly in high-temperature environments. It serves as a critical additive in the production of PVC and other halogenated polymers for industrial applications, where consistent performance and material longevity are essential.

Application

• Primary Heat Stabilizer for rigid and flexible Polyvinyl Chloride (PVC) formulations.
• Lubricant and Processing Aid in the extrusion and calendaring of plastic compounds.
• Stabilizing Component in wire and cable insulation coatings.
• Additive for improving the heat resistance of specialty adhesives and sealants.
• Catalyst and Intermediate in specific organic synthesis processes.
• Used in the formulation of certain corrosion-inhibiting pigments and coatings.
