LEXAN™ Copolymer 923X

LEXAN 923X is based on Polycarbonate (PC) siloxane copolymer resin and is a UV stabilized high flow opaque injection molding (IM) grade. This non-chlorinated, non-brominated flame retardant grade has UL-94 V0 @ 1.5mm flame rating, extreme low temperature ductility (-40°C) characteristics and excellent processability, providing opportunities for shorter IM cycle times compared to standard PC. LEXAN 923X resin is available in a wide range of opaque colours and targeted for a wide range of applications.
