Description

2,2'-Methylenebis[6-Cyclooctyl-p-Cresol] 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 formulators and manufacturers in the polymer, rubber, and lubricant industries to extend product lifespan and maintain material integrity under high-temperature conditions.

Application

• Primary antioxidant in polyolefins (PP, PE) and engineering plastics to prevent thermal-oxidative degradation during processing and service.
• Stabilizer for synthetic rubbers and elastomers, including SBR, BR, and NBR, to enhance aging resistance.
• Additive in lubricating oils, greases, and hydraulic fluids to inhibit oxidation and sludge formation.
• Stabilizing component in hot-melt adhesives and sealants to maintain performance at elevated temperatures.
• Protective agent for hydrocarbon-based resins and waxes against color formation and molecular breakdown.
