PTFE film from Goodfellow is a thin film made of polytetrafluoroethylene, a polymer with exceptional chemical resistance, thermal stability, low friction and electrical insulating properties. With 201 variations, our extensive range of PTFE film thicknesses, sizes and surface finishes supports diverse applications, including electrical insulation, chemical process equipment linings, and low-friction bearings and seals. The inert, non-stick nature of PTFE film also makes it ideal for food processing equipment and medical devices.
