Widely used as an antioxidant in polymers, protecting materials from thermal and oxidative degradation during processing and long-term use. Effective in polyolefins, such as polyethylene and polypropylene, to prevent aging caused by heat, light, and oxygen exposure. Commonly added to plastics, adhesives, and rubber products to extend service life and maintain mechanical properties. Also utilized in lubricants and oils to inhibit oxidation and sludge formation. Suitable for applications requiring high stability at elevated temperatures due to its strong free radical scavenging ability.
