High-performance hindered phenolic antioxidant specifically designed for polyamide (PA6, PA66) processing and long-term thermal stability.
Excellent compatibility and low volatility in high-melting engineering thermoplastics, minimizing blooming and plate-out.
Outstanding hydrolytic stability—retains efficacy even under humid processing conditions and in moisture-sensitive polymers.
Synergistic with phosphite co-stabilizers (e.g., Irgafos 168), enabling optimized stabilization packages for demanding applications.
Non-discoloring performance—preserves polymer clarity and color stability during extrusion, injection molding, and long-term aging.
Stabilization of polyamide 6 (PA6) for automotive under-hood components.
Long-term thermal stabilization of polyamide 66 (PA66) in electrical & electronics housings and connectors.
High-temperature processing aid for glass-fiber reinforced polyamides used in structural engineering parts.
Stabilizer in polyamide-based hot-melt adhesives requiring melt stability and oxidative resistance.
Key additive in food-contact compliant polyamide packaging films (subject to regional regulatory approval).
