High molecular weight benzotriazole UV absorber offering exceptional photostability and long-term UV protection.
Low volatility and excellent compatibility with engineering thermoplastics including polycarbonate, ABS, and polyesters.
Minimal migration and blooming, ensuring surface integrity and clarity retention in demanding applications.
Thermally stable up to 300 °C, enabling safe processing during extrusion, injection molding, and compounding.
Non-discoloring performance—maintains original hue and transparency without yellowing under UV exposure.
Automotive interior and exterior components (e.g., instrument panels, grilles, lamp lenses).
Outdoor construction materials such as window profiles, cladding, and roofing membranes.
Consumer electronics housings requiring high-gloss, color-stable surfaces.
Medical device enclosures where UV resistance and regulatory compliance are critical.
Optical-grade transparent plastics used in signage, lighting diffusers, and display covers.
