Polyvinyl Chloride (PVC) is a versatile thermoplastic polymer widely used in various applications, from pipes and fittings to medical devices and electrical cable insulation. PVC compounds are formulations that include PVC resin and various additives to enhance performance, processing, and final product properties. Components of PVC Compounds: PVC Resin: The primary polymer base. Plasticizers: Added […]

PVC pipes and fittings require stabilizers to address the material’s inherent thermal instability during processing and its susceptibility to degradation under heat, light, and mechanical stress. Key requirements include: 1.Thermal Stability: Prevents decomposition during high-temperature extrusion/molding (160–200°C). 2.Long-term Durability: Resists UV, oxidation, and environmental factors for outdoor applications. 3.Processability: Ensures smooth flow and uniform product
