Description

2,2'-Thiobis[4-Dodecylphenol] is a high-purity phenolic antioxidant and metal deactivator widely used in polymer stabilization. This compound is valued for its ability to effectively inhibit oxidative degradation and chelate metal ions that can catalyze decomposition in various materials. It is an essential additive for manufacturers in the plastics, lubricants, and rubber industries seeking to enhance the longevity and performance stability of their products under demanding conditions.

Application

• Polymer Stabilization: Primary antioxidant for polyolefins (e.g., polyethylene, polypropylene) to prevent thermal and oxidative degradation during processing and end-use.
• Lubricant & Fuel Additive: Functions as an antioxidant and metal deactivator in industrial lubricants, greases, and fuels to extend service life and protect machinery.
• Rubber Industry: Used in the stabilization of synthetic rubbers and elastomers to maintain elasticity and prevent cracking.
• Adhesives & Sealants: Enhances the thermal stability and shelf-life of adhesive formulations and sealants.
• Wire & Cable Insulation: Protects polymeric insulation materials from copper-catalyzed oxidation, ensuring long-term electrical integrity.
• Metal Deactivation: Specifically chelates trace metal ions (e.g., copper, iron) in polymer systems, preventing metal-induced catalytic breakdown.
