High-performance hindered phenolic antioxidant offering exceptional thermal and oxidative stability.
Excellent compatibility with polyolefins, including PP, HDPE, and LDPE, without blooming or migration issues.
Low volatility and high molecular weight ensure long-term stabilization during high-temperature processing.
Synergistic performance when combined with phosphite co-stabilizers (e.g., RIANOX 168) for enhanced melt protection.
Meets global regulatory requirements for food-contact applications under FDA 21 CFR §178.2010 and EU Directive 10/2011.
Polypropylene (PP) fibers and nonwovens for medical and hygiene products.
Automotive interior components such as dashboards, door trims, and air ducts.
Food-grade packaging films and containers requiring FDA-compliant stabilization.
Rotomolded and blow-molded HDPE tanks and industrial containers.
Electrical insulation materials and cable jacketing compounds.
