🔬 Functional Principle and Usage
核心职能 It is a “secondary antioxidant,” primarily working by decomposing hydroperoxides generated during polymer processing, thereby preventing chain reactions that lead to material aging. This effectively prevents thermal oxidative degradation, discoloration (yellowing), and molecular chain scission during processing.

Synergistic Use: It is usually not used alone, but rather compounded with “primary antioxidants” (such as hindered phenol-based IRGANOX series or antioxidant AT-10, etc.) to produce a significant synergistic effect, providing more comprehensive and long-lasting stable protection.
