Description

4-tert-Butyl-2,6-Diisopropylphenol is a sterically hindered phenolic compound that serves as a highly effective antioxidant and polymerization inhibitor. Its molecular structure provides excellent stability, making it a critical additive for protecting materials from oxidative degradation. This product is essential for manufacturers in the polymer, fuel, and specialty chemical industries who require reliable stabilization solutions for their processes and end-products.

Application

• Polymer Stabilizer: Acts as a primary antioxidant in polyolefins (polyethylene, polypropylene), elastomers, and adhesives to prevent thermal and oxidative degradation during processing and service life.
• Fuel & Lubricant Additive: Inhibits gum formation and oxidation in gasoline, jet fuels, and industrial lubricants, extending shelf life and maintaining performance.
• Chemical Intermediate: Used in the synthesis of more complex hindered phenol antioxidants and other specialty chemicals.
• Inhibitor for Monomers: Prevents premature polymerization of styrene, acrylics, and other vinyl monomers during storage and transportation.
• Rubber & Elastomer Protection: Imparts antioxidant properties to synthetic rubbers like SBR, NBR, and EPDM, preventing cracking and loss of elasticity.
• Plasticizer & Resin Stabilizer: Protects PVC and other resin systems from discoloration and molecular breakdown caused by heat and light exposure.

Quality Control

Our production of 4-tert-Butyl-2,6-Diisopropylphenol adheres to stringent quality management protocols. Every batch is analyzed to ensure it meets precise chemical and physical specifications. Certificates of Analysis (COA) documenting purity, identity, and key impurity profiles 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 room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its nature of being easily oxidized, prolonged storage under an inert atmosphere (nitrogen or argon) is recommended for optimal long-term stability.
