Description

N,N'-Bis(1,4-Dimethylpentyl)-p-Phenylenediamine is a high-performance, sterically hindered aromatic amine antioxidant. This compound is engineered to provide exceptional protection against oxidative degradation and thermal aging in demanding industrial environments. It is a critical additive for manufacturers in the polymer and rubber industries seeking to enhance the longevity and stability of their products under harsh operating conditions.

Application

• Rubber Antioxidant: A primary antioxidant for synthetic rubbers like SBR, BR, and NBR, protecting against heat, oxygen, and flex-cracking.
• Polymer Stabilizer: Used in polyolefins (e.g., PP, PE) and other polymers to prevent chain scission and discoloration caused by thermal-oxidative degradation during processing and service life.
• Fuel and Lubricant Additive: Functions as an antioxidant in industrial lubricants, greases, and fuels to inhibit sludge formation and viscosity increase.
• Adhesive and Sealant Formulations: Enhances the shelf-life and durability of polyurethane and other adhesive systems by preventing premature curing and loss of tack.
• Wire and Cable Insulation: Protects the polymeric insulation materials from degradation caused by long-term exposure to heat and electrical stress.
• Automotive Components: Used in the production of hoses, belts, gaskets, and other under-hood parts requiring high thermal resistance.

Quality Control

Our N,N'-Bis(1,4-Dimethylpentyl)-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, melting point, and impurity profiles is provided with each shipment to guarantee consistency and reliability for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized (store under inert atmosphere) and light-sensitive (store away from light). Keep away from strong oxidizing agents, heat, and ignition sources. For long-term storage, consider packaging under an inert gas such as nitrogen.
