Used as an antioxidant in rubber and polymer materials, particularly in tires, to prevent degradation caused by heat, light, and oxygen. It helps extend the service life of rubber products by inhibiting oxidative aging and maintaining elasticity and strength. Also employed in lubricants and greases to improve thermal stability and reduce sludge formation under high-temperature conditions. Its effectiveness in radical scavenging makes it suitable for protecting industrial polymers during processing and long-term use.
