Dan Masakowski, Marmon Innovation presented development of new materials and their testing to meet demanding fire safety and smoke emission standards for cables for railway and metro control cables. Non halogenated materials are needed to achieve smoke limitations. Use of electron beam radiation to ensure cross-linking of cable polymers has enabled to achieve UL94- VW-1 test, with a LSZH (low smoke zero halogen) polyol based cable formulation, which offers a longer time to ignition and lower peak heat release than conventional halogenated flame retardant cable, whereas smoke emission is down to nearly one tenth (passing FT-4 tray burn smoke test).
