Description

Benzenepropanoic acid, 3,5-bis(1,1-dimethylethyl)-4-hydroxy-, 2-3-3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl-1-oxopropoxymethyl-2-(hydroxymethyl)-1,3-propanediyl ester is a high-performance, sterically hindered phenolic antioxidant. This compound is valued for its exceptional ability to inhibit oxidative degradation in a wide range of polymeric materials and organic substrates. It is primarily utilized by manufacturers in the polymer, plastics, and specialty chemical industries seeking to enhance product longevity and stability under demanding conditions.

Application

• Polymer Stabilizer: A primary antioxidant for polyolefins (PP, PE), engineering plastics, and synthetic rubbers to prevent thermal and oxidative degradation during processing and end-use.
• Lubricant & Fuel Additive: Used in formulations for industrial lubricants, greases, and fuels to extend service life by inhibiting oxidation and sludge formation.
• Adhesive & Sealant Formulations: Enhances the shelf-life and performance stability of hot-melt adhesives, pressure-sensitive adhesives, and various sealants.
• Elastomer Protection: Provides critical antioxidant protection in SBR, NBR, and other elastomers against heat and oxygen-induced aging.
• Coating & Resin Additive: Incorporated into protective coatings, paints, and unsaturated polyester resins to prevent yellowing and maintain film integrity.
• Food Contact Material Compliance: Suitable for use in polymer applications requiring compliance with food contact regulations in certain jurisdictions.
