Highly effective long-term UV stabilization for polyolefins and engineering thermoplastics.
Excellent thermal stability up to 300°C, suitable for high-temperature processing such as injection molding and extrusion.
Low volatility and minimal migration, ensuring sustained performance and surface integrity.
Compatible with common antioxidants (e.g., phosphites and hindered phenols) for synergistic stabilization systems.
Non-discoloring formulation—maintains clarity and color fidelity in transparent and light-colored applications.
Polypropylene (PP) automotive interior parts including dashboards, trim, and door panels.
HDPE and LDPE agricultural films requiring extended outdoor UV resistance.
PP and PE geotextiles and geomembranes exposed to harsh sunlight and weathering.
Outdoor furniture and building & construction profiles made from extruded or injection-molded polyolefins.
Blown and cast films for packaging where light stability and clarity retention are critical.
