Highly effective benzotriazole-type UV absorber with strong absorption in the 270–380 nm range.
Excellent compatibility with a broad range of polymers including polyolefins, PVC, PS, ABS, and engineering thermoplastics.
Good thermal stability up to 220 °C, enabling use in high-temperature processing such as extrusion and injection molding.
Low volatility and minimal migration, ensuring long-term stabilization performance in thin-section and outdoor applications.
Non-discoloring and maintains polymer clarity—ideal for transparent and light-colored formulations.
Automotive interior and exterior plastic components (e.g., dashboards, trim, bumpers).
Outdoor construction materials including PVC window profiles, siding, and fencing.
Agricultural films (mulch films, greenhouse covers) requiring extended UV resistance.
Packaging films and containers for UV-sensitive contents (e.g., cosmetics, pharmaceuticals, agrochemicals).
Consumer goods such as garden furniture, toys, and appliance housings exposed to sunlight.
