| About |
|---|
| LEXAN EXL1414T polycarbonate (PC) siloxane copolymer resin is a transparent injection molding grade. This resin offers extreme low temperature (-40 °C) ductility in combination with medium flow characteristics and excellent processability with opportunities for shorter IM cycle times compared to standard PC. LEXAN EXL1414T resin is a general purpose product available in transparent and opaque colors and is an excellent candidate for a broad range of applications.&& |
