Description

N,N'-Dioctyl-p-Phenylenediamine is a high-performance antioxidant and antiozonant belonging to the chemical class of substituted p-phenylenediamines (PPDs). This compound is critical for protecting sensitive materials from oxidative and ozone-induced degradation, thereby significantly extending their service life. It is primarily utilized by manufacturers in the rubber, polymer, and lubricant industries seeking to enhance the durability and performance of their products under demanding environmental conditions.

Application

• Rubber Industry: A key antiozonant and antioxidant for tires, hoses, belts, and seals, protecting against cracking and aging caused by ozone and oxygen.
• Polymer Stabilization: Used as a stabilizer in plastics and synthetic elastomers to prevent thermal and oxidative degradation during processing and end-use.
• Lubricant & Fuel Additive: Functions as an antioxidant additive in industrial lubricants, greases, and fuels to inhibit sludge formation and viscosity increase.
• Wire & Cable Insulation: Protects the polymeric insulation of electrical cables from environmental stress and extends operational lifespan.
• Automotive Components: Essential for under-the-hood components and weather-stripping, providing long-term resistance to heat and ozone.
• Industrial Adhesives and Sealants: Enhances the stability and durability of adhesive formulations exposed to air and sunlight.

Quality Control

Our N,N'-Dioctyl-p-Phenylenediamine is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, color, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee consistency and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality.
