Used as a highly effective stabilizer in polymer systems, particularly in polyolefins such as polyethylene and polypropylene. It protects materials against thermo-oxidative degradation during processing and long-term aging. Exhibits excellent compatibility with other additives like phenolic antioxidants and phosphites, making it ideal for use in multistabilizer formulations. Commonly employed in wire and cable compounds, films, and molded parts where long-term thermal stability and color retention are critical. Shows low volatility and high resistance to extraction, ensuring durable performance under harsh conditions.
