Description

2,6-Bis[(4-Hydroxy-2,5-Dimethylphenyl)Methyl]-4-Methyl Phenol is a high-performance phenolic antioxidant, specifically a hindered phenol, valued for its ability to inhibit oxidative degradation in various polymer systems. This compound is essential for manufacturers seeking to enhance the thermal stability and longevity of their materials by preventing chain scission and discoloration. It is primarily needed by producers in the plastics, rubber, and specialty chemical industries where material durability under oxidative stress is critical.

Application

• Polymer Stabilization: Acts as a primary antioxidant in polyolefins (e.g., polyethylene, polypropylene), engineering plastics, and synthetic rubbers to prevent thermal-oxidative degradation during processing and end-use.
• Adhesive & Sealant Formulations: Incorporated to protect the polymer base from oxidative cross-linking or embrittlement, ensuring consistent performance and shelf life.
• Lubricant & Grease Additive: Used as an antioxidant additive in industrial lubricants and greases to reduce sludge formation and viscosity increase caused by oxidation.
• Elastomer Production: Protects synthetic elastomers like SBR, NBR, and EPDM from ozone and oxygen-induced cracking and loss of mechanical properties.
• Hot Melt Adhesives: Stabilizes adhesive formulations against color development and loss of tackiness caused by exposure to heat and air.
• Fuel & Oil Additives: Serves as an antioxidant in fuels and transformer oils to inhibit gum formation and acid generation.
• Coating Resins: Enhances the weatherability and color stability of solvent-based and powder coating resins.
• Intermediate for Specialty Chemicals: Used in the synthesis of more complex antioxidant systems or polymer-bound stabilizers.

Quality Control

Our production of 2,6-Bis[(4-Hydroxy-2,5-Dimethylphenyl)Methyl]-4-Methyl Phenol adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry benchmarks. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation, especially after opening the original container. Keep away from heat, sparks, and open flame.
