  • Publication number: 20150368495
    Abstract: The present invention provides for a liquid composition for repairing the fluoropolymer insulating sheath of electrical signal-carrying cables, and comprises at least one amorphous fluoropolymer, at least one amorphous perfluoroalkylether and at least one fluorinated solvent. The present invention further provides for a process for repairing an electrically insulating fluoropolymer sheath of an electrical signal-carrying cable, comprising depositing such a liquid composition on at least a damaged area of the fluoropolymer electrically insulating sheath to form at least one layer of liquid composition and evaporating the fluorinated solvent to solidify the liquid composition, as well as the electrical signal-carrying cable obtainable by this process.

  • Patent number: 8674042
    Abstract: The present invention relates to a partially-crystalline copolymer comprising tetrafluoroethylene, hexafluoropropylene in an amount corresponding to HFPI of from about 2.8 to 5.3, and preferably from about 0.2% to 3% by weight of perfluoro(alkyl vinyl ether), said copolymer having less than about 50 ppm alkali metal ion, having a melt flow rate of within the range of about 30±3 g/10 min, and having no more than about 50 unstable endgroups/106 carbon atoms and which can be extruded at high speed onto conductor over a broad polymer melt temperature range to give insulated wire of high quality.
