Features Of BASF Tinuvin 479 Hydroxyphenyl-Triazine UV Absorber

  1. Exceptional long-term UV stability in demanding outdoor applications due to its hydroxyphenyl-triazine molecular architecture.

  2. High molar extinction coefficient across UVA and UVB ranges (300–400 nm), ensuring efficient photon absorption at low loadings.

  3. Excellent compatibility and low volatility in high-performance polyolefins, engineering thermoplastics, and thermoset systems.

  4. Outstanding thermal stability up to 280 °C, supporting high-temperature processing such as injection molding and extrusion.

  5. Non-basic, non-migrating structure that minimizes interaction with acid-sensitive additives and pigments.

Typical Applications Of BASF Tinuvin 479 Hydroxyphenyl-Triazine UV Absorber

  1. Polypropylene (PP) automotive interior and exterior components exposed to sunlight.

  2. HDPE and LDPE geomembranes and agricultural films requiring multi-year UV resistance.

  3. Polycarbonate (PC) and PC/ABS blends for outdoor electronic enclosures and lighting housings.

  4. Unsaturated polyester (UP) and vinyl ester resins used in fiber-reinforced composites for construction and marine applications.

  5. Coated and laminated industrial packaging films where clarity and photostability are critical.
