Used as a high-performance antioxidant in polymers, protecting materials from thermal and oxidative degradation during processing and long-term use. Commonly added to polyolefins, engineering plastics, and elastomers to extend service life by preventing cracking, discoloration, and loss of mechanical strength. Also applied in adhesives, sealants, and masterbatches where stability under heat and stress is critical. Effective in both melt processing and end-product stabilization, often combined with other stabilizers for synergistic effects. Widely utilized in automotive, electrical, and packaging industries where durability and performance under harsh conditions are required.
