Description

2,6-Di-tert-Butylphenol is a sterically hindered phenolic compound widely recognized for its role as a versatile antioxidant and chemical intermediate. Its primary commercial value lies in its ability to inhibit oxidative degradation, thereby extending the service life of polymers, fuels, and other sensitive materials. This product is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product stability and performance.

Application

• Polymer Stabilizer: Acts as an effective antioxidant in the production and processing of polyolefins (e.g., polyethylene, polypropylene), synthetic rubbers, and other polymers to prevent thermal and oxidative degradation.
• Fuel & Lubricant Additive: Used as an antioxidant additive in gasoline, jet fuels, and industrial lubricants to improve oxidation stability and prevent gum formation.
• Chemical Intermediate: Serves as a key building block in the synthesis of more complex hindered phenol antioxidants, such as Irganox® and other proprietary stabilizer systems.
• UV Stabilizer Synergist: Works in conjunction with other stabilizers to enhance the light stability of plastics and coatings.
• Inhibitor for Monomers: Used to prevent premature polymerization of monomers like styrene and acrylics during storage and transportation.
• Antioxidant for Elastomers: Protects synthetic and natural rubbers from oxidative aging, maintaining elasticity and mechanical properties.

Quality Control

Our 2,6-Di-tert-Butylphenol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, melting point, and impurity profile are provided to guarantee consistent quality and traceability for our global B2B clients.

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 product integrity. Keep away from strong oxidizing agents.
