Tetrafluoroethylene is a fluorocarbon resin, the fluoropolymer commonly known as PTFE.
Tetrafluoroethylene, abbreviated TFE, is a fluorocarbon, or fluoropolymer, resin, the material commonly known in its polymerized form as PTFE, polytetrafluoroethylene. As a fluoropolymer, it offers outstanding resistance to heat and chemicals along with excellent dielectric properties, including a low dielectric constant and low loss. These qualities make TFE a premier insulation material for demanding wire and cable.
Because it withstands very high temperatures, resists virtually all chemicals, and provides stable, low-loss electrical performance, TFE insulation serves the most demanding high-temperature and high-frequency applications. It does not melt and flow like ordinary thermoplastics, so it is processed by specialized methods such as sintering.
In commercial and industrial cable, TFE fluoropolymer insulation serves high-temperature and high-frequency roles where ordinary materials would fail. Recognizing the term and its relationship to PTFE helps in understanding high-performance cable.
