| About |
|---|
| LEXAN EXL1112 polycarbonate (PC) siloxane copolymer resin is a high flow opaque injection molding (IM) grade. This resin offers good low temperature (-20 C) ductility in combination with excellent processability and release with opportunities for shorter IM cycle times compared to standard PC. LEXAN EXL1112 resin is a product available in wide range of opaque colors and may be an excellent candidate for a wide variety of applications.&& |
