  • Applications

    Chemical name: 1,3,5-Trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzene; CAS number: 1709-70-2. This high-molecular-weight hindered phenolic compound is used primarily as an antioxidant and stabilizer in polymer formulations and related materials. In practice, it serves as a processing and long-term stabilizer for plastics and polyolefins, helping to resist thermal-oxidative degradation during compounding, extrusion, and service. It is also employed in coatings and inks as a protective antioxidant to prevent color change and yellowing. In lubricants and industrial oils, it acts as an antioxidant to extend oil life and protect metal surfaces. It can also be used as a stabilizer in rubbers and in adhesive formulations to improve aging resistance.
