|---|
| LEXAN 920 Polycarbonate (PC) resin is a non-filled, injection moldable grade. This brominated flame retardant PC has a UL V0 rating and is available in limited opaque color options. LEXAN 920 resin is a general-purpose resin that is an excellent candidate for a wide variety of applications. As a non-chlorinated, non-brominated flame retardant solution, LEXAN 925 resin could be considered an alternative.&& |
