Description

Lead Phthalate CAS NO 16183-12-3 is a specialized organometallic compound primarily used as a heat stabilizer and catalyst in polymer formulations. This product is critical for enhancing the thermal processing stability and longevity of various plastic materials, particularly PVC, under demanding conditions. It serves as an essential additive for manufacturers in the plastics, cable insulation, and specialty chemical industries seeking to improve product performance and durability.

Application

• Primary Heat Stabilizer for polyvinyl chloride (PVC) resins in wire and cable insulation, flooring, and profiles.
• Catalyst and Co-catalyst in esterification and polymerization reactions for producing polyesters and other polymers.
• Lubricant Additive to enhance the extreme pressure (EP) and anti-wear properties of industrial greases and oils.
• Stabilizing Agent in the production of certain pigments and dyes to prevent degradation during processing.
• Research & Development chemical for synthesizing novel organolead compounds and studying catalytic mechanisms.
• Specialty Additive for sound-damping materials and vibration-resistant composites.
