High molecular weight HALS offering exceptional long-term UV stability and thermal resistance.
Low volatility and low migration, ensuring excellent permanence in demanding polymer applications.
Synergistic performance with UV absorbers (e.g., benzotriazoles) for enhanced photoprotection.
Excellent compatibility with polyolefins, engineering plastics, and thermoplastic elastomers.
Non-discoloring formulation suitable for light- and heat-sensitive color systems.
Polypropylene (PP) automotive interior parts including dashboards, door panels, and trim.
Exterior polyethylene (PE) geomembranes and agricultural films requiring multi-year UV endurance.
Thermoplastic polyurethane (TPU) cables and outdoor technical textiles.
Polycarbonate (PC) and PC/ABS blends used in lighting housings and electronic enclosures.
Recycled polyolefin compounds where stabilization against processing-induced degradation is critical.
