Widely used as an antioxidant in plastics, rubber, and synthetic fibers, this compound prevents degradation caused by heat and oxidation during processing and extended use. It stabilizes polymers such as polyethylene and polypropylene, enhancing their lifespan and maintaining mechanical properties under high-temperature conditions. Commonly added during manufacturing of films, containers, and pipes, it protects against environmental stress and UV exposure. Also employed in lubricants and greases to inhibit oxidation and reduce sludge formation, improving performance and longevity. Its low volatility and good compatibility with organic matrices make it suitable for high-temperature applications.
