Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate is widely used as a high-performance antioxidant in the polymer industry. It is particularly effective in stabilizing polyolefins, such as polyethylene and polypropylene, against thermal degradation during processing and long-term use. The compound helps to prevent the formation of free radicals, which can cause chain scission and degradation of the polymer, thereby extending the material's lifespan and maintaining its mechanical properties. Additionally, it is utilized in applications where polymers are exposed to harsh environmental conditions, such as UV radiation, heat, and oxidative stress, making it suitable for use in automotive parts, packaging materials, and construction products. Its ability to provide long-term stability also makes it valuable in the production of synthetic fibers and elastomers.
