This chemical is primarily utilized as a stabilizer and antioxidant in various polymer systems, particularly in plastics and synthetic rubbers. It helps to prevent degradation caused by oxidation, heat, and light exposure, thereby extending the lifespan and maintaining the mechanical properties of the materials. It is especially effective in polyolefins, such as polyethylene and polypropylene, where it enhances thermal stability during processing and end-use applications. Additionally, it finds use in lubricants and fuels to inhibit oxidative breakdown, ensuring smoother operation and longer service life of machinery. Its ability to scavenge free radicals makes it valuable in protecting sensitive materials from environmental stressors.
