  • Applications

    2,6-Di-tert-butyl-4-ethylphenol (CAS 4130-42-1) is primarily used as an antioxidant and stabilizer in polymers and elastomers, helping to prevent thermal and oxidative degradation of plastics, rubbers, and related additives. It is commonly employed as an oxidation stabilizer in coatings and paints and in inks to enhance durability and color stability. It also serves as an antioxidant additive for lubricants and fuels, helping to prevent degradation under heat. In processing, it may function as a stabilizer for adhesives and plastics, and can act as an intermediate in the synthesis of other antioxidants. Use is subject to local regulations and formulation limits.
