Description

Lead Phthalate, Dibasic is an organolead compound primarily used as a heat stabilizer and lubricant in polymer formulations. Its value lies in its ability to enhance the thermal processing stability and mechanical properties of various plastics, particularly PVC, by scavenging degrading hydrochloric acid. This makes it a critical additive for manufacturers in the plastics, cable, and specialty chemical industries seeking to improve product longevity and performance under heat stress.

Application

• Primary heat stabilizer for polyvinyl chloride (PVC) and other halogenated polymers.
• Key component in lubricant and stabilizer packages for rigid and flexible PVC applications, including pipes, profiles, and cables.
• Used in the production of specialty pigments and corrosion-inhibiting coatings.
• Acts as a catalyst or catalyst component in select organic synthesis reactions.
• Employed in the formulation of certain sealants and adhesives requiring thermal stability.
• Utilized in research and development for material science studies on polymer additives.
