High-performance phosphite antioxidant offering exceptional melt stability for polyolefins during high-temperature processing.
Excellent hydrolytic stability, minimizing degradation in humid or aqueous processing environments.
Low volatility and low extractability, ensuring long-term stabilization and compliance with food-contact regulations.
Synergistic with hindered phenols (e.g., Irganox 1010), enabling optimized primary/secondary antioxidant systems.
Non-staining and colorless, preserving clarity and hue in sensitive optical and packaging applications.
Polypropylene (PP) fibers and nonwovens for medical and hygiene products.
Blown and cast polyethylene (PE) films used in food packaging and agricultural mulch.
Injection-molded PP automotive interior components requiring heat resistance and low odor.
Rotomolded HDPE tanks and containers exposed to elevated thermal cycling.
Recycled polyolefin compounds where processing stability and reversion control are critical.
