Sabic Lexan EXL1182T resin is polycarbonate (PC) siloxane copolymer resin is a UV stabilized, enhanced release transparent injection molding (IM)grade. This resin offers good low temperature (-20 C) ductility in combination with high flow characteristics and excellent processability with opportunities for shorter IM cycle times compared to standard PC resins. Lexan EXL1182T resin is a UV stabilized, enhanced release product available in transparent and opaque colors and may be an excellent candidate for a broad range of applications.
