Synergistic Effect of Sodium Aluminium Silicate and Fischer-Tropsch Waxes on the Thermal Stability of CPVC Compounds

Abstract

A Chlorinated Polyvinyl Chloride (CPVC) compound with enhanced static and dynamic thermal stability, improving the performance of pipes and fittings, is disclosed. The CPVC compound broadly comprises the following components: a Chlorinated Polyvinyl Chloride resin, an organotin stabilizer, pigments, lubricants, an impact modifier, a processing aid, and an acid scavenger.

The disclosed CPVC compound provides the following synergistic advantages:

• Requires a lower concentration of the tin stabilizer.
• Enables easy processing without scorching, ensuring a uniform surface appearance for pipes and fittings, thereby enhancing their aesthetic quality.
• Improves both static and dynamic thermal stability, contributing to superior performance and durability.
