Applications of ePTFE: Advanced Dielectric Materials


People rely on their ability to send and receive information, whether it’s communicated from smartphones, satellites or the infrastructures around us. Just as we depend on information, the wires and cables transporting information depend on dielectric materials to shield conductors, maintain signal reliability, and ensure that constant, lightning-quick dispatches can go through.

Gore’s expertise in advanced dielectric materials dates back to the founding of the company. In 1958, Bill Gore saw an opportunity to pair his technological expertise in PTFE with a growing need for cabling in the computer industry; our first product, MULTI-TET™ wire and cable, soon followed. In the years since, our solutions for computing and telecommunications have transmitted information from satellites, the Apollo 11 moon-landing mission and the Mars Rover; enabled critical communication in military aircraft; contributed to wide-ranging test and measurement applications; and allowed passengers to enjoy WiFi on commercial flights.

Our products offer superior performance because of their electrical strength, insulation properties and mechanical toughness, which enable them to maintain signal and power even in the most demanding environments. This is possible due to the materials’ powerful combination of PTFE and ePTFE:

  • PTFE is chemically inert and hydrophobic, and therefore isn’t affected by chemicals or water that can cause other materials to lose their mechanical properties at high temperatures.
  • ePTFE has great mechanical strength and flexibility, keeping the material in our products cut- and scrape-resistant even at high temperatures.
  • ePTFE has a highly porous structure that allows signals to travel at nearly the speed of light — with minimal loss or distortion.

Today, Gore’s portfolio for dielectric applications includes cables and cable assemblies for high data rate, power and signal delivery, and spaceflight; motor windings and capacitors; and a variety of shielding gaskets and grounding pads. Whether these products are used for commercial flights, space exploration, computing, test and measurement, or defense applications, they continuously provide the signal strength our modern world expects and requires.
