| About |
|---|
| LEXAN EXL1443T polycarbonate (PC) siloxane copolymer resin is an injection molding grade with FDA and EU food contact compliance. This resin offers excellent low temperature (-30 C) ductility in combination with medium flow characteristics and excellent processability with opportunities for shorter IM cycle times compared to standard PC. LEXAN EXL1443T resin is available in transparent and opaque colors and is an excellent candidate for a broad range of food contact applications.&& |
