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 […]

Methyl tin mercaptide stabilizer is a type of tin stabilizer used in polyvinyl chloride (PVC) products. Methyl tin mercaptide stabilizers are used to improve the heat stability, UV resistance, and flame retardance of PVC. Methyl tin mercaptide stabilizers contain the chemical element tin, which is bound to organic compounds known as alkyl tin compounds, hence
