Description

Ethylene Bis[(Decylthio)Acetate] is a specialized organosulfur compound primarily utilized as a high-performance antioxidant and metal deactivator. This chemical matters for its ability to effectively inhibit oxidation and stabilize materials against degradation caused by heat, light, and metal ions. It is needed by formulators and manufacturers in the polymer, lubricant, and fuel industries seeking to extend product lifespan and enhance performance under demanding conditions.

Application

• Polymer Stabilizer: Used as an antioxidant and metal deactivator in polyolefins (e.g., polyethylene, polypropylene) to prevent thermal and oxidative degradation during processing and end-use.
• Lubricant & Grease Additive: Enhances the oxidative stability of industrial lubricants and greases, protecting against viscosity increase and sludge formation.
• Fuel & Oil Additive: Acts as a stabilizer in fuels and transformer oils to prevent gum formation and acid generation, thereby protecting metal components.
• Rubber Industry: Provides antioxidant protection for synthetic rubbers, helping to maintain elasticity and prevent cracking.
• Adhesive & Sealant Formulations: Improves the long-term stability and performance of adhesive and sealant products by inhibiting oxidative cross-linking and embrittlement.
• Wire & Cable Insulation: Used as a stabilizer in plastic insulation materials to protect against copper-catalyzed degradation.
