High-performance hindered amine light stabilizer (HALS) with exceptional long-term UV protection.
Excellent compatibility with polyolefins, including PP and HDPE, without blooming or migration issues.
Thermally stable up to 300 °C, enabling use in high-temperature processing such as extrusion and injection molding.
Low volatility and minimal odor—suitable for sensitive applications including automotive interior components and food-contact-compliant packaging.
Synergistic performance when combined with UV absorbers (e.g., benzotriazoles) and antioxidants for enhanced weatherability.
Automotive exterior parts: bumpers, trim, and under-hood components exposed to intense sunlight and thermal cycling.
Outdoor agricultural films: mulch films, greenhouse covers, and silage wraps requiring extended service life under UV radiation.
Geotextiles and civil engineering membranes used in road construction, landfill liners, and erosion control.
Consumer goods: garden furniture, playground equipment, and outdoor storage containers made from polypropylene or polyethylene.
Rotomolded tanks and large-volume containers for water, chemicals, and fuel storage.
