What Is PTFE?
PTFE is the abbreviation for polytetrafluoroethylene, which is a fluoropolymer used in a variety of applications and industries. Most people recognize PTFE as the nonstick coating used in cookware. In the wire and cable industry, PTFE is used as insulation and jacketing material for several types of cable, including coaxial cable.

What Are the Benefits of PTFE in Coaxial Cable?
The properties of PTFE make it a great choice for coax cable. PTFE coaxial cable is very non-reactive and has a low dielectric constant rating, especially at high frequencies. This means that PTFE coax won’t hold as much electrostatic charge as other dielectric materials with a higher dielectric constant rating.

Which Types of Coaxial Cable Use PTFE?
There are several types of coaxial cables that use PTFE as the dielectric, the jacket, or even both.
