Description

n-(4-(1,1,3,3-Tetramethylbutyl))Phenyl-1-Naphthylamine is a high-performance, sterically hindered aromatic amine antioxidant. This compound is valued for its effectiveness in preventing oxidative degradation and extending the service life of various polymeric materials. It is primarily utilized by manufacturers in the polymer, rubber, and lubricant industries seeking to enhance product stability and durability under demanding conditions.

Application

• Primary antioxidant in the stabilization of polyolefins (e.g., polyethylene, polypropylene) against thermal and oxidative degradation during processing and end-use.
• Critical additive in synthetic rubber and elastomer formulations to prevent chain scission and crosslinking, maintaining flexibility and mechanical properties.
• Stabilizer component in industrial lubricants and greases to inhibit oil thickening and sludge formation under high-temperature operation.
• Used in adhesive and sealant chemistries to protect the polymer matrix from aging and embrittlement.
• Antioxidant for petroleum-derived products, including fuels and certain specialty oils, to improve shelf life and performance.
• An intermediate in the synthesis of more complex light stabilizers and antioxidant blends for advanced polymer systems.

Quality Control

Our n-(4-(1,1,3,3-Tetramethylbutyl))Phenyl-1-Naphthylamine is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing, including assay and impurity profile determination by HPLC, to ensure it meets precise specifications for use in sensitive polymer applications. A comprehensive Certificate of Analysis (COA) documenting purity, identity, and physical properties is provided with each shipment to guarantee traceability and consistency.

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; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) in the container headspace is recommended. Keep away from strong oxidizing agents.
