Description

2,2'-Methylenebis(6-Cyclohexyl-4-Methyl)Phenol is a high-performance sterically hindered phenolic antioxidant. This compound is valued for its excellent thermal stability and effectiveness in preventing oxidative degradation in demanding environments. It is primarily utilized by manufacturers in the polymer, rubber, and specialty lubricant industries to extend product lifespan and maintain material integrity under high-temperature and high-stress conditions.

Application

• Polymer Stabilizer: A key antioxidant for polyolefins (e.g., PP, PE), engineering plastics, and synthetic fibers to prevent thermal-oxidative degradation during processing and end-use.
• Rubber Industry: Provides long-term antioxidant protection in synthetic rubbers, elastomers, and tire components, enhancing durability and resistance to heat aging.
• Lubricant & Grease Additive: Used in synthetic lubricants, industrial greases, and metalworking fluids to inhibit oxidation, reduce sludge formation, and extend oil life.
• Adhesive & Sealant Formulations: Improves the thermal stability and shelf life of hot-melt adhesives, epoxy resins, and polyurethane systems.
• Fuel & Petrochemical Additive: Acts as a stabilizer in fuels and hydrocarbon streams to prevent gum formation and oxidative degradation.
• Co-additive Synergy: Often used in combination with secondary antioxidants (e.g., phosphites, thioesters) and light stabilizers for synergistic stabilization packages.
