Highly effective UV absorption in the 290–400 nm range, providing broad-spectrum protection against photodegradation.
Excellent thermal and hydrolytic stability, ensuring consistent performance during high-temperature processing and long-term service life.
Low volatility and minimal migration, maintaining UV protection integrity in polymer matrices over time.
Good compatibility with a wide range of polymers including polyolefins, ABS, polycarbonate, and engineering plastics.
Non-discoloring and low extractability, supporting clear, stable end-product aesthetics and regulatory compliance.
Automotive interior and exterior plastic components exposed to intense sunlight.
Outdoor building materials such as PVC window profiles, roofing membranes, and cladding systems.
Transparent packaging films and rigid containers for pharmaceuticals and food-grade applications.
Coatings and inks requiring long-term color retention and gloss stability under UV exposure.
Engineering thermoplastics used in consumer electronics housings and outdoor appliances.
