  • Applications

    4,4',4''-(1-Methylpropanyl-3-ylidene)tris(6-tert-butyl-m-cresol) is a multifunctional hindered phenol antioxidant used as an oxidative and thermal stabilizer for polymers and rubber. In plastics processing, it commonly serves as a thermal stabilizer for polyolefins, PVC, and polyester, helping extend product life and resist degradation under heat. It is also employed as an antioxidant additive in lubricants and petroleum-derived products, and as a stabilizer in coatings and inks to prevent oxidation and color changes. Additionally, it is often evaluated for use in adhesives and synthetic rubber formulations to improve aging resistance and chemical durability, subject to local regulations and formulation limits. CAS number: 1843-03-4.
