LNP™ ELCRES™ FST2734E

LNP ELCRES FST2734E is a glass fiber reinforced Polycarbonate (PC) Copolymer Resin for sheet extrusion and part production by thermoforming processes. This UV stabilized, flame retardant resin, is intended for train interior applications requiring EN 45545 R1–HL2 compliant materials (e.g. side panels & partition walls). It also meets requirements of FRA and NFPA-130 standards. Available in opaque colors.
