  • Applications

    2,4-Di-tert-pentylphenol (CAS 120-95-6) is a hindered phenolic antioxidant used primarily as a stabilizer in plastics and rubber, helping to prevent thermal and oxidative degradation in polyolefins, elastomers, coatings and adhesives. It is also employed as an antioxidant additive in lubricants and may serve as an intermediate in the synthesis of other antioxidant additives; the scope of use may extend to coatings and inks formulations. Usage should be subject to local regulations and formulation limits.
