LNP™ ELCRES™ CRX7412U

LNP ELCRES CRX7412U is an unfilled, amorphous Polycarbonate (PC) copolymer resin that offers medium flow, non-chlorinated/brominated flame retardant grade. This grade is available for custom coloring, has UL V0 rating @ 1.2 mm for all colors, low temperature ductility and is UV stabilized. The grade has improved chemical resistance against a wide range of disinfectants compared to standard PC/ABS blends and is a good candidate for thin wall applications and hospital/medical equipment.
