Description

N,N'-Di-sec-Butyl-p-Phenylenediamine is a high-performance aromatic amine antioxidant and antiozonant. This compound is critical for protecting polymers and elastomers from oxidative degradation and ozone cracking, thereby significantly extending their service life. It is an essential additive for manufacturers in the rubber, polymer, and lubricant industries seeking to enhance product durability and performance under demanding conditions.

Application

• Rubber Antiozonant & Antioxidant: Primary use as a protective agent in tire sidewalls, seals, gaskets, hoses, and other rubber goods exposed to atmospheric ozone and oxygen.
• Polymer Stabilizer: Imparts excellent long-term thermal stability to polyolefins (e.g., polyethylene, polypropylene) and other synthetic polymers during processing and end-use.
• Lubricant & Fuel Additive: Functions as an antioxidant in industrial lubricants, greases, and fuels to prevent sludge formation and viscosity increase.
• Wire & Cable Insulation: Protects the polymeric insulation materials in electrical cables from heat- and oxygen-induced degradation.
• Adhesive & Sealant Formulations: Enhances the aging resistance and shelf-life of polyurethane and other adhesive systems.
• Industrial Elastomers: Used in the production of NBR, SBR, EPDM, and neoprene for automotive, construction, and industrial applications.

Quality Control

Our N,N'-Di-sec-Butyl-p-Phenylenediamine is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and physical properties is provided with each shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its nature as an easily oxidized compound, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Recommended storage temperature: 15-25°C.
