Widely used as a high-performance antioxidant in polymers, this compound protects materials against 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 molecular weight changes caused by heat and oxygen exposure. Commonly added during polymer manufacturing, it stabilizes products exposed to high temperatures, such as automotive parts, electrical cables, and household containers. It also finds use in adhesives, sealants, and lubricants where long-term durability is critical. Due to its low volatility and good compatibility with organic matrices, it remains active throughout the material’s lifecycle without migrating to the surface or evaporating easily.
