Description

2,2'-(Octahydro-4,7-Methano-1H-Indenediyl)Bis[6-tert-Butyl-p-Cresol] is a high-performance, sterically hindered phenolic antioxidant. This compound is critical for preventing oxidative degradation and extending the service life of polymers and synthetic materials. It is primarily needed by manufacturers in the polymer, rubber, and lubricant industries to ensure product stability and performance under demanding conditions.

Application

• Polymer Stabilization: Primary antioxidant for polyolefins (e.g., PP, PE), engineering plastics, and synthetic fibers to inhibit thermal-oxidative degradation during processing and end-use.
• Rubber Industry: Essential additive in the production of synthetic rubbers (SBR, BR, NBR) and tires to prevent cracking and maintain elasticity.
• Lubricant & Grease Formulation: Used in industrial and automotive lubricants, hydraulic fluids, and greases to enhance oxidative stability and prevent sludge formation.
• Adhesive & Sealant Production: Protects adhesive polymers from premature aging, ensuring long-term bond integrity and flexibility.
• Fuel & Petrochemical Additive: Acts as a stabilizer in fuels, oils, and petrochemical intermediates to prevent gum and sediment formation.
• Elastomer Manufacturing: Provides antioxidant protection in various elastomeric products, including hoses, belts, and gaskets.
