Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate（Cat No.:R058709）is a high-performance antioxidant and stabilizer used in polymers and plastics. Structurally, it features an isocyanurate core bonded to three sterically hindered phenolic groups, each substituted with tert-butyl groups at the 3 and 5 positions. This configuration provides exceptional thermal stability, oxidation resistance, and long-term protection against degradation caused by heat, light, and oxygen. It is especially effective in polyolefins, styrenics, and engineering plastics. Due to its low volatility and high molecular weight, it remains embedded in polymer matrices, offering prolonged protective performance in demanding industrial applications.
