Heat Stabilizer for PVC

PVC Stabilizer is a crucial additive used in the processing of polyvinyl chloride (PVC) to protect it from thermal degradation during manufacturing and throughout its service life. It ensures color stability, prevents chain scission, and enhances the durability of PVC products exposed to heat, light, and mechanical stress. PVC stabilizers are available in various types, including lead-based, calcium-zinc (Ca-Zn), organotin, and mixed metal stabilizers, each suited for different applications depending on regulatory, environmental, and performance requirements.
