High-molecular-weight, sterically hindered phenolic antioxidant offering exceptional long-term thermal stability.
Excellent compatibility with polyolefins, engineering plastics, and elastomers without blooming or migration.
Low volatility ensures sustained protection during high-temperature processing (e.g., extrusion, injection molding).
Synergistic performance when combined with phosphite co-stabilizers such as Irgafos 168.
Meets stringent regulatory requirements including FDA 21 CFR §178.2010 and EU Directive 10/2011 for food-contact plastics.
Polyethylene (PE) and polypropylene (PP) films, fibers, and injection-molded parts.
Automotive interior and under-hood plastic components exposed to elevated temperatures.
Medical-grade polyolefin tubing, syringes, and packaging requiring oxidative stability and biocompatibility.
Rotational-molded tanks and large industrial containers for chemical storage.
Cable & wire insulation materials based on cross-linked polyethylene (XLPE) and thermoplastic elastomers.
