Sabic Lexan PC EXL5689 Description
Lexan* EXL5689 polycarbonate (PC) siloxane copolymer resin is a 9% GF reinforced, UV stabilized, flame retardant injection molding grade. This medium flow resin combines UL94 V0 @ 1.5mm, 5VB @ 3.0mm flame retardancy based on non-chlorine, non-bromine FR agents with excellent processability and improved release performance. Lexan EXL5689 resin offers much improved impact strength and ductility over conventional GF reinforced PC resins. This product is available in limited opaque colors (BK, WH & GY) only and may be an excellent candidate for a broad range of applications, i.e. electrical and electronic enclosure applications.
