High-performance hindered amine light stabilizer (HALS) specifically optimized for polyethylene (PE) applications.
Excellent compatibility and dispersion in polyolefin matrices without blooming or plate-out issues.
Thermally stable up to 260 °C, enabling robust performance during high-temperature extrusion and molding processes.
Low volatility and minimal extractability, supporting long-term stabilization in demanding outdoor environments.
Designed for synergistic use with UV absorbers (e.g., benzotriazoles) to enhance overall photostability.
Rotomolded polyethylene tanks and containers for chemical and water storage.
Blown and cast PE films used in agricultural mulch, greenhouse covers, and geomembranes.
Extruded PE pipes and fittings for potable water, irrigation, and gas distribution systems.
Injection-molded PE parts exposed to prolonged sunlight, including automotive under-hood components and outdoor furniture.
