EB crosslinked ethylene tetrafluoroethylene (ETFETefzel
™) wire is also used in aircraft airframes. This
insulation is thinner and lighter than the materials
used for comparable wires. It can be used at
temperatures up to 200 degrees Celcius and will
perform temperatures as low as -65 °C [9]. In general,
fluoropolymers are superior to the polyolefins, such as
polyethylene, for very high temperature applications
