Description

n-(1,3-Dimethylbutyl)-N'-Phenyl-p-Phenylenediamine is a high-performance antioxidant and antiozonant belonging to the p-phenylenediamine (PPD) class of chemical compounds. This product is critical for protecting rubber and polymer materials from oxidative and ozone-induced degradation, thereby significantly extending their service life. It is an essential additive 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: Used extensively in the vulcanization of natural rubber (NR) and synthetic rubbers like styrene-butadiene rubber (SBR) and polybutadiene rubber (BR) to prevent oxidation and heat aging.
• Antiozonant for Tire Manufacturing: A key ingredient in tire sidewalls and other exposed rubber components to protect against cracking and degradation caused by atmospheric ozone.
• Stabilizer for Industrial Rubber Goods: Employed in the production of hoses, belts, seals, gaskets, and other mechanical rubber goods to ensure long-term durability.
• Protective Agent for Polymer Blends: Used in various polymer systems and blends to inhibit thermal-oxidative degradation during processing and end-use.
• Additive for Automotive Components: Incorporated into rubber parts for vehicles, including engine mounts, bushings, and weather stripping, to enhance weatherability.
