Description

2,6-Diisopropyl-4-Methylphenol CAS NO 20766-99-8 is a sterically hindered phenolic compound widely recognized for its excellent antioxidant properties. This chemical is a critical intermediate and performance additive, valued for its ability to inhibit oxidation and stabilize formulations against degradation. It is essential for manufacturers in the polymer, fuel, lubricant, and specialty chemical industries seeking to enhance product longevity and performance under demanding conditions.

Application

• Polymer Stabilizer: Acts as a highly effective antioxidant in the production of polyolefins (e.g., polyethylene, polypropylene), synthetic rubbers, and other polymers to prevent thermal and oxidative degradation during processing and service life.
• Fuel & Lubricant Additive: Used as an antioxidant additive in gasoline, diesel, jet fuels, and industrial lubricants to improve stability, reduce gum formation, and extend shelf life.
• Chemical Intermediate: Serves as a key building block in the synthesis of more complex hindered phenol antioxidants, phosphite stabilizers, and other specialty organic compounds.
• Industrial Antioxidant: Employed in adhesives, sealants, coatings, and elastomers to protect against oxidative cross-linking and embrittlement.
• Preservative Agent: Finds application in select industrial preservation systems where non-metallic, phenolic antioxidants are required.
