LNP™ ELCRES™ EXL1212L

ELCRES EXL1212L polycarbonate (PC) siloxane copolymer resin is a medium to high flow opaque injection molding (IM) grade. This resin offers good low temperature -20°C ductility and weld line appearance in combination with excellent processability with opportunities for shorter IM cycle times compared to standard PC. ELCRES EXL1212L resin is a product available in wide range of opaque colors and specifically designed for chemical plating process.
