Used primarily as an antioxidant in rubber and plastic industries to prevent degradation caused by oxygen, ozone, and heat. It enhances the durability and lifespan of products like tires, conveyor belts, and industrial hoses. Also employed in lubricants to inhibit oxidation and extend the usability of oils and greases. In the polymer industry, it stabilizes materials against thermal and oxidative breakdown during processing and storage. Additionally, it finds application in the production of synthetic fibers to maintain their strength and flexibility over time.
