SABIC LNP™ ELCRES™ EXL7414 Polycarbonate (PC)
Categories:	Polymer; Thermoplastic; Polycarbonate (PC)
Material Notes:	LNP ELCRES EXL7414 is based on Polycarbonate (PC) siloxane copolymer resin. It is a medium flow, non-chlorinated, non-brominated flame retardant opaque grade. It offers excellent low temperature ductility (-40C), extremely thin wall flame retardant capability with UL94 V0 at 0.6mm, and in combination with excellent processability and release with opportunities for shorter cycle times compared to standard Polycarbonate. It is available in wide range of opaque colors and is an excellent candidate for a wide variety of applications such as the battery cover of fast-charging mobile phones that need to be compliant with IEC62368-1. Features: Enhanced Low Temperature Impact,Flame Retardant,Non-Chlorinated,Non-Brominated,High Impact Resistance,Good Mold Release,Exceptional Processing Information provided by SABIC
