PTFE Cast Film

FLONFILM™ 100

About PTFE Cast Film

PTFE cast film (FLONFILM™ 100) is a single layer, multi-laminar film manufactured using the cast method. By virtue of this unique process, FLONFILM™ 100 PTFE film (PolyTetraFluoroEthylene) has a number of high performance features not inherent in skived tapes or extruded films.

It is uniform in material structure, exhibits outstanding chemical, physical & electrical properties and is tightly controlled in its thickness (+/-10%). Based on its capability to act as a semi-permeable membrane, FLONFILM™ 100 PTFE film is used in oxygen sensors & similar devices in bio-medical and other instrumentation.

Polyflon offers cast PTFE film in semi-finished form on standard rolls or converted into finish punched components in custom shapes ready for immediate assembly in to your device.
