  • Applications

    4,4'-Butylidenebis(3-methyl-6-tert-butylphenol) (CAS 85-60-9) is primarily used as a phenolic antioxidant and thermal stabilizer for plastics and elastomers, protecting formulations from heat- and oxygen-induced degradation; typical applications include stabilizing polymers (polyolefins and PVC) and rubber compounds, serving as an antioxidant in lubricants and fuels, stabilizing coatings and inks to resist oxidation, and acting as an additive in adhesives formulations to improve oxidative stability and longevity.
