Highly effective secondary antioxidant based on phosphite chemistry for hydroperoxide decomposition.
Excellent thermal stability and low volatility, supporting high-temperature polymer processing.
Good compatibility with polyolefins, engineering plastics, and elastomers without blooming or migration.
Synergistic performance when combined with primary antioxidants such as hindered phenols (e.g., Irganox 1010).
Low color formation during processing, preserving clarity and aesthetic quality in final products.
Polypropylene (PP) fibers and nonwovens for hygiene and medical applications.
Polyethylene (PE) films used in packaging and agricultural mulch.
Automotive interior components including PP-based dashboards and trim parts.
Injection-molded engineering plastic compounds for electrical and electronic housings.
Recycled polyolefin formulations requiring stabilization against thermo-oxidative degradation.
