Used as a high-performance antioxidant and stabilizer in polymers, particularly in polyolefins such as polyethylene and polypropylene. It protects materials from thermal and oxidative degradation during processing and extends service life by preventing UV-induced breakdown. Commonly employed in cables, films, and molded parts where long-term stability is required. Also found in adhesives and elastomers to maintain mechanical properties under heat and light exposure. Shows excellent compatibility with other additives, allowing synergistic effects in stabilization packages.
