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. Offers excellent stability at high temperatures and helps maintain mechanical properties, color, and structural integrity of plastics exposed to heat and UV light. Commonly used in wires, cables, films, and molded parts where extended service life and resistance to aging are critical. Also effective in adhesives, sealants, and elastomers to prevent hardening and cracking over time.
