| LEXAN 943 Polycarbonate (PC) resin is a non-filled, injection moldable grade. This brominated flame retardant PC has a UL-94 V0 rating and is UV stabilized, providing additional weathering capability. LEXAN 943 resin is available in limited opaque color options and is a general-purpose resin ideal for a wide variety of applications. As a non-chlorinated, non-brominated flame retardant solution, LEXAN 945U resin could be considered an alternative.&& |
