High-performance phosphite antioxidant offering exceptional hydrolytic stability in demanding processing conditions.
Excellent melt stabilization for polyolefins during extrusion, injection molding, and blow molding operations.
Synergistic compatibility with phenolic antioxidants (e.g., ADK STAB AO-20, AO-50) for enhanced long-term thermal aging resistance.
Low volatility and minimal plate-out tendency, supporting clean production and consistent product quality.
Meets stringent regulatory requirements for food-contact applications compliant with FDA 21 CFR §178.2010 and EU Regulation (EC) No. 10/2011.
Polypropylene (PP) homopolymers and copolymers for automotive interior parts and under-hood components.
Polyethylene (PE) films, including heavy-duty shipping sacks and agricultural mulch films requiring extended outdoor durability.
Transparent PP and PE packaging containers subjected to high-temperature filling and sterilization processes.
Fiber and nonwoven applications such as spunbond and meltblown PP used in hygiene and medical products.
Recycled polyolefin compounds where stabilization against thermo-oxidative degradation during multiple reprocessing cycles is critical.
