SABIC LEXAN™ Copolymer EXL1434 PC (Americas) (Unverified Data**)
Categories:	Polymer; Thermoplastic; Polycarbonate (PC)
Material Notes:	LEXAN EXL1434 polycarbonate (PC) siloxane copolymer resin is a medium flow opaque injection molding (IM) grade and is UV stabilized. This resin offers extreme low temperature (-40 C), exhibits excellent processability and release with opportunities for shorter IM cycle times compared to standard PC. LEXAN EXL1434 resin is a product available in wide range of opaque colors and may be an excellent candidate for a wide variety of applications. Information provided by SABIC
