SABIC LEXAN™ Copolymer MPX2 Polycarbonate (PC)
Categories:	Polymer; Thermoplastic; Polycarbonate (PC)
Material Notes:	LEXAN MPX2 polycarbonate (PC) siloxane copolymer resin is a injection molding (IM) grade with release properties. This resin offers good low temperature ductility in combination with medium flow characteristics and excellent processability with opportunities for shorter IM cycle times compared to standard IM PC resins. LEXAN MPX2 resin is a general purpose product available for wide range of colors and may be an excellent candidate for a broad range of applications. Features: High Impact Resistance Information provided by SABIC
