Technical Capabilities

Unparalled Technical Knowledge and Experience


As the company that invented expanded PTFE and introduced it in the marketplace, Gore offers an unparalleled level of technical knowledge and experience. This know-how starts with a deep scientific understanding of fluoropolymers, particularly PTFE processing and fluoropolymer development. From that core technical base, Gore’s expertise extends across a variety of applications. Gore’s unique technical agility enables the development of a wide range of processes and creative, reliable technologies.

Expanded PTFE Configuration Capabilities

Expanded PTFE is Gore’s core technology, a technology that Gore produces:

  • in multiple forms: tapes, membranes/films, tubes, fibers, sheets and rods,
  • with varied structures: high or low density, tight or open porosity, thin or thick, surface or cross-section orientation, multiple geometries and asymmetries
  • and various proprietary modifications that enable us to produce highly valuable end products.

Examples of forms:

  • Tapes: electronic wires and cables
  • Membranes/films: GORE-TEX® laminates, filtration laminates, stent grafts, vents, fuel cell membrane electrode assemblies, dielectric materials, battery/capacitor separators
  • Sheets: electromagnetic interference gaskets, sealing gaskets, medical patches
  • Fibers: weaving/sewing threads, dental floss, packings, filtration felts
  • Tubes: peristaltic pump tubes, vascular grafts, environmental screening modules
