This compound is primarily used as a stabilizer in polymer systems, especially in polyolefins such as polyethylene and polypropylene. It functions as a chelating agent that deactivates metal ions, particularly transition metals like iron, copper, and nickel, which can catalyze the degradation of polymers during processing and long-term use. By sequestering these metal ions, the compound helps prevent oxidative degradation, thereby improving the thermal stability and extending the service life of plastic materials. It is especially effective in applications requiring long-term heat aging resistance, such as in cables, pipes, and automotive components. Its sterically hindered structure enhances performance by providing stability under high processing temperatures and reducing discoloration. Due to its low volatility and good compatibility with polymer matrices, it remains effective throughout the product's lifespan without significant migration or loss.
