High-performance HALS technology offering exceptional long-term UV resistance in demanding outdoor applications.
Low volatility and excellent thermal stability, ensuring minimal loss during high-temperature polymer processing.
Good compatibility with polyolefins, engineering plastics, and elastomers without blooming or migration issues.
Non-basic structure minimizes interference with acid-sensitive additives such as phosphites or certain pigments.
Environmentally compliant—free of heavy metals and REACH-conformant for sustainable formulation design.
Polypropylene (PP) automotive interior parts exposed to sunlight and elevated cabin temperatures.
HDPE and LDPE geomembranes used in landfill liners and pond covers requiring decades of UV integrity.
Outdoor agricultural films including mulch films and greenhouse covers subject to intense solar radiation.
UV-stabilized PVC profiles for window frames and siding in architectural applications.
Thermoplastic elastomer (TPE) components in consumer goods and outdoor equipment.
