Description

1-Naphthalenamine, n-[(1,1,3,3-Tetramethylbutyl) Phenyl]-, Polymer With 4-Octyl-n-(4-Octylphenyl)Benzenamine is a high-performance polymeric amine antioxidant designed for demanding industrial applications. This compound is valued for its exceptional ability to inhibit oxidative degradation and extend the service life of sensitive materials. It is a critical additive for manufacturers in the polymer, rubber, and specialty lubricant industries seeking to enhance product stability under thermal and oxidative stress.

Application

• Polymer Stabilization: Primary antioxidant in polyolefins (e.g., polyethylene, polypropylene) to prevent chain scission and discoloration during processing and long-term use.
• Rubber Industry: Protects synthetic rubbers (SBR, BR, NBR) and tires from heat aging and flex-cracking.
• Lubricant & Fuel Additive: Used in engine oils, greases, and industrial lubricants to reduce sludge formation and viscosity increase.
• Adhesive & Sealant Formulations: Enhances the shelf-life and performance stability of hot-melt and pressure-sensitive adhesives.
• Engineering Plastics: Provides thermal-oxidative stability to high-temperature resins like polyamides (nylons) and polyesters.
• Elastomer Production: Essential for stabilizing EPDM and other elastomers used in automotive and construction seals.

Quality Control

Our production of this polymeric antioxidant adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality is verified through a suite of analytical tests including determination of active content, molecular weight distribution, and color. A Certificate of Analysis (COA) detailing purity, physical properties, and performance tests is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources, open flames, and strong oxidizing agents. Due to its light-sensitive nature, containers should be kept in the original packaging or opaque containers until use.
