Widely used as a high-performance antioxidant in polymers, this compound prevents degradation caused by heat and oxidation during processing and long-term use. It is especially effective in polyolefins, such as polyethylene and polypropylene, where it maintains material strength, color, and flexibility over time. Commonly found in automotive parts, electrical cables, and outdoor-exposed plastics due to its excellent thermal stability. Also used in adhesives, sealants, and elastomers to extend service life. Compatible with other stabilizers, allowing synergistic formulations for enhanced protection.
