Exceptional long-term UV stability in demanding outdoor applications due to its hydroxyphenyl-triazine molecular architecture.
High molar extinction coefficient across UVA and UVB ranges (300–400 nm), ensuring efficient photon absorption at low loadings.
Excellent compatibility and low volatility in high-performance polyolefins, engineering thermoplastics, and thermoset systems.
Outstanding thermal stability up to 280 °C, supporting high-temperature processing such as injection molding and extrusion.
Non-basic, non-migrating structure that minimizes interaction with acid-sensitive additives and pigments.
Polypropylene (PP) automotive interior and exterior components exposed to sunlight.
HDPE and LDPE geomembranes and agricultural films requiring multi-year UV resistance.
Polycarbonate (PC) and PC/ABS blends for outdoor electronic enclosures and lighting housings.
Unsaturated polyester (UP) and vinyl ester resins used in fiber-reinforced composites for construction and marine applications.
Coated and laminated industrial packaging films where clarity and photostability are critical.
