Description

N,N'-Dicyclohexyl-p-Phenylenediamine CAS NO 4175-38-6 is a high-performance substituted p-phenylenediamine derivative, primarily valued for its role as an antioxidant and antiozonant in polymer stabilization. Its chemical structure provides excellent protection against thermal and oxidative degradation, extending the service life of critical materials. This product is essential for manufacturers in the rubber, polymer, and specialty chemical industries seeking to enhance product durability and performance under demanding conditions.

Application

• Rubber Antioxidant/Antiozonant: A key additive in the production of synthetic rubbers (e.g., SBR, NBR, EPDM) to prevent cracking and degradation caused by ozone and oxygen exposure.
• Polymer Stabilizer: Used in polyolefins and other engineering plastics to inhibit thermal-oxidative degradation during processing and end-use.
• Fuel and Lubricant Additive: Functions as an antioxidant in industrial lubricants and fuels to prevent gum formation and viscosity increase.
• Urethane Catalyst/Stabilizer: Employed in polyurethane systems to enhance stability and performance characteristics.
• Chemical Intermediate: Serves as a building block in the synthesis of more complex antioxidants, dyes, and pharmaceutical agents.
• Wire and Cable Insulation: Incorporated into polymer compounds for electrical insulation to improve long-term aging resistance.
