Kel-F® - PCTFE

Kel-F® - PCTFE (PolyChloroTriFluoroEthylene) is a fluorocarbon-based polymer and is commonly abbreviated PCTFE. This material offers the unique combination of physical and mechanical properties, nonflammability, chemical resistance, near zero moisture absorption, and excellent electrical properties. These characteristics cannot be found in any other thermoplastic fluoropolymer with a useful temperature range of +204 deg C to minus 204 deg C. PCTFE also has extremely low outgassing, making it well suited for use in aerospace and flight applications.
Note: Kel-F® is a registered tradename of 3M Company. In 1996, 3M discontinued the manufacture of Kel-F & today, all PCTFE resin is manufactured by Daikin under the tradename of Diaflon ® or by Allied Signal under the tradename of Aclon ®. Kel-F is still the most commonly used tradename used to describe PCTFE.
