Highly effective long-term UV stabilization for polyolefins and engineering plastics.
Low volatility and excellent thermal stability up to 280 °C during processing.
Non-migrating molecular structure ensures superior permanence in demanding applications.
Synergistic compatibility with phenolic antioxidants and other HALS systems.
Minimal impact on color development and polymer clarity, even after prolonged UV exposure.
Automotive interior and exterior plastic components (e.g., dashboards, bumpers, trim).
Agricultural films including greenhouse and mulch films requiring multi-season durability.
Geotextiles and civil engineering membranes exposed to intense solar radiation.
Polypropylene and polyethylene fibers for outdoor textiles and ropes.
Blown and cast packaging films where light stability and clarity retention are critical.
