Description

N,N'-1,6-Hexanediyl Bis[3-(1,1-Dimethylethyl)-4-Hydroxy-5-Methyl]-Benaenepropanamide is a high-performance phenolic antioxidant and metal deactivator belonging to the class of hindered amine light stabilizer (HALS) synergists. This compound matters for its exceptional ability to prevent thermal and oxidative degradation in demanding polymer systems, thereby significantly extending material lifespan and performance. It is critically needed by manufacturers in the plastics, synthetic fiber, and specialty elastomer industries who require robust stabilization against harsh environmental and processing conditions.

Application

• Polymer Stabilization: Primary antioxidant for polyolefins (PP, HDPE, LDPE), polyamides (nylon), and engineering plastics to prevent thermal-oxidative degradation during processing and end-use.
• Synergistic Additive: Used in combination with primary antioxidants and HALS to enhance the overall light and heat stability of polymer formulations, particularly in automotive and construction applications.
• Metal Deactivation: Functions as a metal deactivator in wire and cable insulation, protecting polymers from catalytic degradation caused by contact with metal ions (e.g., copper).
• Synthetic Fibers: Imparts stability to synthetic fibers like polypropylene and polyamide fibers, maintaining strength and color during high-temperature extrusion and long-term exposure.
• Adhesives and Sealants: Enhances the durability and shelf-life of hot-melt adhesives and industrial sealants by preventing oxidative cross-linking and embrittlement.
• Elastomer Protection: Stabilizes synthetic rubbers and thermoplastic elastomers (TPEs) against heat aging, preserving elasticity and mechanical properties.
