Application
UV ABSORBER HOSORB UV 120 is substituted benzoate that absorbs ultraviolet radiation and through a reversible chemical rearrangement, dissipates the energy as heat. It is no color contamination, low volatility, high thermal stability, excellent resistance to washing and extraction. It exhibits a synergistic effect in combination with HALS.
As light stabilizer and antioxidant, it can be used in the polymer. It is suitable for polyethylene, polypropylene, polystyrene, PU, TPU and other products, especially suitable for polypropylene films, coatings, adhesives and fiber.
