Sabic Lexan EXL1880T resin is polycarbonate (PC) siloxane copolymer resin is a UV stabilized, transparent injection molding grade. This resin offers good low 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. Lexan EXL1880T resin is a UV stabilized, improved release product available in transparent and opaque colors and is an excellent candidate for a broad range of applications.
