  • Applications

    2,2'-Methylenebis(4-methyl-6-nonylphenol) (CAS 7786-17-6) is a hindered phenolic antioxidant commonly used as a stabilizer in polymer systems to prevent thermal-oxidative degradation during processing and in finished articles; typical applications include stabilization of polyolefins (PE, PP), PVC, and engineering plastics, helping to retard aging and preserve color. It is also used as an antioxidant additive for rubber and elastomers to improve resistance to aging. In lubricants and hydraulic fluids, it functions as an antioxidant/stabilizer to extend service life under high-temperature conditions. In coatings, inks, and related surface finishes, formulations may include this compound to enhance UV/oxidative stability and color retention. Additionally, it can be incorporated into adhesives and sealants as a stabilizer to improve long-term performance.
