Primarily used as a stabilizer in polymers, particularly in polyolefins like polyethylene and polypropylene, to prevent degradation caused by heat and oxidation. It effectively scavenges free radicals, enhancing the durability and lifespan of plastic products exposed to high temperatures or UV radiation. Commonly applied in the production of automotive parts, packaging materials, and construction components where thermal stability is critical. Additionally, it finds use in synthetic rubbers and elastomers to maintain their mechanical properties under harsh conditions. Its antioxidant properties also make it suitable for coatings and adhesives, ensuring long-term performance and resistance to environmental stressors.
