MG-Guard UV-531

MG-Guard UV-531 is a solid benzophenone UV absorber that is especially effective at absorbing higher energy UV-B radiation. This absorber imparts colorfastness, protection against surface crazing, and retention of physical properties during ultraviolet exposure to a number of polymer systems, including: polyolefins (PE, PP) and rubber-modified poly­olefins (TPO, TPV), styrenics (ABS, SAN, ASA, PS) rigid/flexible PVC, TPU, and EVA, among others. Features & Benefits: Strong UV-B absorption for especially sensitive pigments or polymers; Low initial color; Low melting point affords facile processing and dispersibility; Excellent synergy with hindered amine light stabilizers (HALS)
