LNP™ ELCRIN™ EXL4419G

Sustainable Grade

LNP ELCRIN EXL4419G polycarbonate (PC) siloxane copolymer resin is a 9% Glass Fiber (GF) reinforced opaque injection molding (IM) grade, that incorporates renewable feedstock through ISCC+ mass-balance certification. This medium flow resin offers much higher ductility, improved release characteristics and excellent processability with opportunities for shorter IM cycle times when compared to GF reinforced standard PC resins. EXL4419G resin is available in opaque colors only and is an excellent candidate for a broad range of applications that require a combination of stiffness and ductility.
