Description

2,2-Bis(4-(2-(3,5-Di-Tert.Butyl-4-Hydroxyhydrocinnamoyloxy)Ethoxy)Phenyl)Propane is a high-performance, sterically hindered phenolic antioxidant widely used to protect polymers from oxidative degradation. Its molecular structure provides excellent long-term thermal stability, making it a critical additive for extending the service life of sensitive materials. This compound is essential for manufacturers in the plastics, rubber, and synthetic fiber industries who require reliable protection against heat and oxygen-induced chain scission and discoloration.

Application

• Polymer Stabilization: Primary antioxidant for polyolefins (PP, PE), engineering plastics, and synthetic rubbers to prevent thermal-oxidative degradation during processing and end-use.
• Food Contact Materials: Used in polymer formulations for packaging where regulatory compliance and non-migration properties are required.
• Adhesives and Sealants: Enhances the shelf-life and performance stability of hot-melt and reactive adhesive systems.
• Elastomers and Synthetic Fibers: Protects spandex, polyurethane, and other fibers from strength loss and yellowing caused by heat and light exposure.
• Masterbatch Production: A key active component in antioxidant and stabilizer concentrate formulations for easier dispersion in final polymer compounds.
• Lubricant and Fuel Additives: Functions as an antioxidant in synthetic lubricants and greases to inhibit sludge formation and viscosity increase.
