Description

2,6-Bis(1-Methyl-1-Phenylethyl)-4-Nonylphenol is a sterically hindered phenolic compound that functions as a highly effective antioxidant and stabilizer. Its molecular structure provides superior protection against oxidative degradation in various polymeric and organic systems. This product is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance the longevity and performance stability of their formulations.

Application

• Primary antioxidant and stabilizer in polyolefins (e.g., polyethylene, polypropylene) to prevent thermal and oxidative degradation during processing and service life.
• Additive in lubricating oils, greases, and hydraulic fluids to inhibit oxidation and extend fluid life under high-temperature operating conditions.
• Stabilizer component in adhesives, sealants, and elastomers to maintain material integrity and prevent premature aging.
• Intermediate in the synthesis of other specialized phenolic antioxidants and polymer additives.
• Protective agent in fuel and petrochemical products to minimize gum and sludge formation.
• Stabilizing additive for synthetic resins and coatings to improve weatherability and color retention.

Quality Control

Our production of 2,6-Bis(1-Methyl-1-Phenylethyl)-4-Nonylphenol adheres to a stringent quality management system to ensure batch-to-batch consistency and high purity. Standard quality parameters include assay by HPLC, color, and melting point determination. A Certificate of Analysis (COA) detailing all test results is provided with each shipment, and we can support compliance with relevant regulatory frameworks such as REACH.

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) is recommended to preserve efficacy. Keep away from strong oxidizing agents.
