SABIC LEXAN™ Copolymer EXL1444 Polycarbonate (PC) (Europe)
Categories:	Polymer; Thermoplastic; Polycarbonate (PC)
Material Notes:	Lexan* EXL1444 polycarbonate (PC) siloxane copolymer resin is a medium flow opaque injection molding (IM) grade suitable for FDA compliant applications. This resin offers extreme low temperature (-40°C) ductility, exhibits excellent processability and release with opportunities for shorter IM cycle times compared to standard PC. Lexan EXL1444 resin is a product available in wide range of opaque colors and may be an excellent candidate for a wide variety of food contact applications. Features: High Impact Resistance Information provided by SABIC
