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 ensures long-term protection during high-temperature processing such as extrusion and injection molding.
Synergistic with phosphite co-stabilizers (e.g., RIANOX 168) for enhanced melt stabilization and color retention.
Meets stringent 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 including dashboards, trim, and under-hood parts.
Food-grade packaging films and containers requiring extended shelf-life stability.
Rotomolded and blow-molded HDPE tanks, drums, and industrial containers.
Masterbatch formulations for UV- and heat-sensitive polymer systems.
