Teflon Wire Types

Polytetrafluorethylene (PTFE)

• Polytetrafluorethylene, or PTFE, is the more common type of Teflon wire. It comes in three different voltage ratings: 250, 600 and 100. The thickness of the wire determines its voltage rating. PTFE wire is commonly used for electronics and electrical equipment in which wires will be exposed to high heat. It comes in different colors, gauges (thicknesses) and lengths.

Fluorinatedethylenepropylene (FEP)

• Fluorinatedethylenepropylene, or FEP, is a chemically inert wire, meaning it does not react to chemicals or gasses. This makes it ideal for outdoor or underground use where it may be exposed to different elements. FEP wire can also be exposed to higher temperatures than can PTFE. You can find the color, guage and length that you need.

Tetrafluorethylene (TFE)

• Tetrafluorethylene, or TFE, uses tape instead of an outer shell to insulate the wire. Like the other types of Teflon wire, TFE also come in many lengths and thicknesses.
