Highly effective UV absorption in the 270–380 nm range, providing robust protection against photodegradation.
Excellent compatibility with a broad spectrum of polymers including polyolefins, ABS, polycarbonate, and PVC.
Outstanding thermal stability up to 280 °C, suitable for high-temperature processing such as extrusion and injection molding.
Low volatility and minimal migration, ensuring long-term UV resistance without surface blooming or plate-out.
Good hydrolytic stability and resistance to extraction by water or common solvents during service life.
Automotive interior and exterior plastic components (e.g., dashboards, bumpers, trim).
Outdoor construction materials including PVC window profiles, roofing membranes, and cladding panels.
Packaging films and containers for UV-sensitive products such as agrochemicals and pharmaceuticals.
Coatings and inks for industrial and decorative applications requiring weatherfastness and color retention.
Engineering plastics used in consumer electronics housings and outdoor lighting fixtures.
