Description

n-(1,3-Dimethylbutyl)-N'-Phenyl-p-Phenylenediamine CAS NO 793-24-8 is a high-performance antioxidant and antiozonant belonging to the p-phenylenediamine (PPD) chemical class. It matters for its critical role in protecting rubber and polymer materials from oxidative degradation and ozone cracking, thereby significantly extending product service life. This compound is essential for manufacturers in the tire, automotive parts, and industrial rubber goods industries who require reliable protection against environmental stressors.

Application

• Primary Antioxidant in Rubber Compounding: Widely used as a staining antioxidant and antiozonant in the production of tires, conveyor belts, hoses, and seals.
• Automotive Components: Protects rubber parts such as engine mounts, bushings, and weatherstripping from heat and ozone-induced aging.
• Industrial Rubber Goods: Essential for extending the lifespan of industrial products like gaskets, O-rings, and diaphragms exposed to harsh conditions.
• Polymer Stabilization: Functions as a stabilizer in various polymer systems to prevent degradation during processing and end-use.
• Fuel and Lubricant Additive: Acts as an antioxidant additive in certain specialty fuels and lubricants to inhibit oxidation and sludge formation.
• Wire and Cable Insulation: Used in rubber-based insulation and jacketing to protect against environmental stress and prolong electrical integrity.
