LNP™ ELCRES™ SLX2471MT

LNP ELCRES SLX2471MT is an amorphous Polycarbonate (PC) copolymer resin. It is an injection moldable, weatherable product that offers enhanced UV stabilization. This medium flow (16 MVR) resin provides good processability with added mold release. This halogen-free flame retardant resin is EN45545 R4 HL3 and R27 HL3 compliant and an ideal candidate for transparent train applications.
