Low density PTFE tape – also known as “expanded PTFE” (ePTFE) is made from pure PTFE film that has been expanded (stretched) under specific and tightly controlled conditions to achieve low dielectric constant and high tensile strength.
The result of the stretching process, besides the lower density, is a very low dielectric constant and high tensile strength.

The high mechanical properties helps cable manufacturers to improve efficiency in their production process, by enabling faster wrapping speeds
As a binder tape in cable bundles, its low weight and excellent conformability adds minimal mass and volume to the cable construction.
The low dielectric constant makes low density PTFE tapes one the best dielectric materials in coaxial cable constructions
