Description

2-[(2-Benzoyloxy-3-tert-Butyl-5-Methylphenyl)Methyl]-6-tert-Butyl-4-Methylphenol is a high-performance hindered phenolic antioxidant, valued for its exceptional ability to inhibit oxidative degradation in polymers and other sensitive materials. Its molecular structure provides superior thermal stability and low volatility, making it a critical additive for extending the service life and maintaining the properties of finished products. This compound is essential for manufacturers in the plastics, rubber, and specialty chemical industries seeking reliable protection against heat- and oxygen-induced aging.

Application

• Polymer Stabilization: Primary antioxidant for polyolefins (PP, PE), engineering plastics, and synthetic rubbers to prevent chain scission and cross-linking during processing and end-use.
• Lubricant & Fuel Additive: Used in formulations for industrial lubricants, greases, and fuels to enhance oxidative stability and reduce sludge formation.
• Adhesive & Sealant Protection: Incorporated into hot-melt adhesives, sealants, and caulks to prevent viscosity increase and maintain elasticity over time.
• Elastomer Manufacturing: Protects synthetic rubbers like SBR, NBR, and EPDM from premature aging, preserving tensile strength and flexibility.
• Coating & Resin Systems: Functions as a stabilizer in protective coatings, unsaturated polyester resins, and polyurethane systems to prevent yellowing and embrittlement.
• Synergistic Formulations: Often used in combination with secondary antioxidants (e.g., phosphites, thioesters) for enhanced, long-term stabilization performance.
