  • Applications

    As a hindered phenolic antioxidant, tert-Butyl methylphenoxy phenol is used as a stabilizer in polymers and plastics to suppress thermal-oxidative degradation during processing and use. It is commonly applied in polyolefins and vinyl resins, adhesives, and coatings to improve long-term aging resistance; it can function as an antioxidant additive in lubricants and greases to extend service life; in rubber and elastomer formulations it helps prevent degradation under heat and shear; it may also serve as a processing aid or stabilizer in adhesive systems and sealants. Chemical name: tert-Butyl methylphenoxy phenol; CAS 307000-42-6.
