SABIC LEXAN™ Copolymer EXL1890T Polycarbonate (PC) (Europe)
Categories:	Polymer; Thermoplastic; Polycarbonate (PC)
Material Notes:	LEXAN EXL1890T polycarbonate (PC) siloxane copolymer resin is a transparent injection molding grade for food contact applications. This resin offers cold temperature (0 °C) ductility in combination with very high flow characteristics and excellent processability with opportunities for shorter IM cycle times compared to standard PC resin. LEXAN EXL1890T resin offers enhanced release performance and is available in transparent colors and is an excellent candidate for a broad range of applications in food handling or food preparation markets. Features: High Impact Resistance Information provided by SABIC
