Widely used as an anti-aging additive in polymers, especially in polyolefins such as polyethylene and polypropylene. It protects materials from degradation caused by heat and ultraviolet (UV) light during processing and long-term outdoor exposure. This compound acts as a hydroperoxide decomposer, stabilizing the polymer chain reactions that lead to oxidation. It is particularly effective in agricultural films, packaging films, and molded or extruded products where extended service life and clarity are important. Its low volatility and good compatibility with polymers make it suitable for high-temperature processing. Also used in combination with other stabilizers like hindered phenols and UV absorbers for synergistic effects.
