This compound is primarily used as a stabilizer in polymer systems, especially in polyolefins such as polyethylene and polypropylene. It functions as a highly effective antioxidant by chelating pro-oxidant metal ions, particularly copper and iron, which can accelerate the degradation of plastics. By deactivating these metal ions, the compound helps prevent discoloration, molecular weight loss, and embrittlement of the polymer during processing and long-term use. It is especially valuable in applications requiring extended thermal and oxidative stability, such as in cables, pipes, and films exposed to high temperatures or harsh environments. Due to its low volatility and good compatibility with polymer matrices, it remains active over prolonged periods, enhancing the service life of the material. Its sterically hindered structure contributes to improved resistance against hydrolysis and weathering, making it suitable for both indoor and outdoor applications.
