Widely used as a high-performance antioxidant in polymers, this compound protects materials from thermal and oxidative degradation during processing and long-term use. It is especially effective in polyolefins, such as polyethylene and polypropylene, where it prevents discoloration, embrittlement, and loss of mechanical properties caused by heat and light exposure. Commonly added to plastics used in automotive parts, electrical components, and household goods, it ensures durability and maintains appearance over time. It also finds use in adhesives, sealants, and elastomers, where long-term stability is critical. Due to its high molecular weight and low volatility, it provides long-lasting protection without migrating to the surface or evaporating during high-temperature processing.
