Extruded FEP, ETFE and PFA wires are best option for wiring where working temperature is higher, these insulating materials give better dielectric strength in very thin insulation thickness, which makes these wires and cables of lesser diameter comparative to other high voltage wires, This property is most desirable in various cable harness manufacturing to save space.
Apart from high temperature, these insulating materials are with smooth surface, chemical resistant, UV resistant, Flexible and flame retardant. These wires are resistant to most of solvents and oils that’s why recommended for use in chemical plants for long life.
