Description

Benzenepropanoicacid,3,5-Bis(1,1-Dimethyl-Ethyl)-44Hydroxy-C7-C9Branchedalkylesters is a high-performance phenolic antioxidant ester, specifically designed for superior stabilization in demanding polymer systems. Its primary value lies in its ability to effectively inhibit oxidative degradation, thereby extending the service life and maintaining the physical properties of materials under thermal and environmental stress. This compound is essential for formulators and manufacturers in the plastics, rubber, and synthetic lubricant industries who require robust, long-term protection for their products. The CAS number for this compound is provided in the basic information below.

Application

This specialized antioxidant ester is engineered for high-performance stabilization across several key industrial sectors.

• Polymer Stabilization: Primary antioxidant for polyolefins (PP, PE), engineering plastics, and synthetic rubbers to prevent thermal-oxidative degradation during processing and end-use.
• Lubricant and Fuel Additives: Used in synthetic engine oils, industrial lubricants, and fuels to enhance oxidative stability and reduce sludge formation.
• Adhesive and Sealant Formulations: Protects polymer-based adhesives, sealants, and caulks from embrittlement and loss of adhesive properties caused by oxidation.
• Elastomer Production: Critical for stabilizing SBR, EPDM, and other synthetic elastomers against heat aging, preserving elasticity and tensile strength.
• Hot-Melt Adhesives (HMA): Prevents discoloration and maintains viscosity stability in hot-melt adhesive applications during high-temperature processing.
• Wire and Cable Insulation: Incorporated into polyethylene and cross-linked polyethylene (XLPE) compounds to protect insulation materials from long-term thermal aging.
