Widely used as a high-performance antioxidant in polymers, particularly in polyolefins such as polyethylene and polypropylene. Offers excellent thermal stability during processing and long-term protection against oxidative degradation. Commonly applied in wire and cable insulation, pipes, and automotive components where prolonged heat and stress resistance are required. Also effective in elastomers and adhesives to prevent aging and maintain mechanical properties under harsh conditions. Shows good compatibility with other stabilizers, allowing synergistic formulations for enhanced performance.
