Highly effective long-term photostabilization for polymers exposed to intense UV radiation and thermal stress.
Low volatility and excellent compatibility with a broad range of thermoplastics and thermosets.
Superior hydrolytic stability, maintaining performance in humid or outdoor weathering conditions.
Synergistic with UV absorbers (e.g., benzotriazoles) and antioxidants for enhanced stabilization systems.
Non-discoloring and low migration, preserving aesthetic integrity and surface properties over time.
Polyolefins — including PP and HDPE films, fibers, and automotive interior components.
Engineering plastics — such as ABS, PC/ABS blends, and polyamides used in exterior automotive parts.
Coatings and inks — particularly high-performance industrial and automotive clearcoats requiring gloss retention.
Roofing membranes and geomembranes — where extended UV resistance and dimensional stability are critical.
Outdoor agricultural films — including mulch and greenhouse films subjected to prolonged solar exposure.
