  • Patent number: 7409815
    Abstract: A wire rope including at least one metal wire and at least one fluoropolymer fiber. Preferably, the fluoropolymer fiber is present in an amount less than about 25 weight %, and in alternative embodiments less than 20 weight %, 15 weight %, 10 weight %, and 5 weight %. The fluoropolymer fiber is preferably PTFE, and most preferably expanded polytetrafluoroethylene (ePTFE). The wire rope is useful in tensioned and bending applications.
