Description

2,2'-[1,3,4-Thiadiazole-2,5-Diylbis(Dithio)]Bis[4-Dodecylphenol] is a specialized phenolic antioxidant and metal deactivator with a high molecular weight. This compound matters for its superior ability to inhibit oxidative degradation and chelate metal ions, thereby extending the service life of sensitive materials. It is primarily needed by formulators in the polymer, lubricant, and fuel additive industries seeking advanced stabilization solutions for high-performance applications.

Application

• Polymer Stabilization: Acts as a highly effective antioxidant and metal deactivator in polyolefins (e.g., polyethylene, polypropylene), engineering plastics, and synthetic rubbers to prevent thermal and oxidative degradation during processing and end-use.
• Lubricant & Grease Additives: Used in industrial lubricants, gear oils, and greases to enhance oxidative stability, reduce sludge formation, and protect against catalytic degradation from metal surfaces.
• Fuel & Petrochemical Additives: Employed in gasoline and diesel additives to improve storage stability, prevent gum formation, and act as a metal deactivator, protecting fuel systems.
• Adhesive & Sealant Formulations: Provides long-term stability in hot-melt adhesives, sealants, and other polymer-based systems susceptible to heat and oxidation.
• Wire & Cable Insulation: Imparts critical long-term thermal aging resistance to the polymeric insulation and jacketing materials used in electrical cables.
• Elastomer Protection: Used in the stabilization of synthetic elastomers like SBR, NBR, and EPDM against metal-catalyzed oxidation, preserving mechanical properties.
