Abstract:
1. A limited combustible (LC) Cable wherein one or more of the Cable components has a composition comprised of polyvinylidene fluoride (PVDF) and from about 0.05 to 0.5 weight %, based on the weight of the PVDF, of a flame and smoke suppressant, provided that the Cable contains—less than 50 weight % PVDF, based on the weight of the Cable wherein the PVDF comprises a homopolymer of PVDF or a copolymer prepared from at least 75 percent by weight of vinylidene fluoride monomer; wherein the LC cable has a potential heat value (PHV) below 3500 BTU/pound when tested by standard NFPA-259, and when tested by Standard NFPA-255 has a smoke developed index (SDI) below 50 and a flame developed index (FDI) below 25; and wherein the flame and smoke suppressant is selected from the group consisting of one or more of a tungstate, and a molybdate.
