Used as a high-performance antioxidant in polymers, particularly in polyolefins such as polyethylene and polypropylene. It protects materials from thermal and oxidative degradation during processing and long-term use, especially at elevated temperatures. Offers excellent stability and low volatility, making it suitable for applications requiring extended service life under harsh conditions. Commonly found in wires, cables, and automotive components where thermal resistance and durability are critical. Also used in adhesives and sealants to maintain performance under heat aging.
