Extruded and Compression Molded Grade • Translucent Color



PolyChloroTriFluoroEthylene is a fluorocarbon-based polymer and is commonly abbreviated PCTFE. The Kel-F brand is a registered trademark of 3M, but they discontinued production in 1995. The only remaining brand, Neoflon, is made by Daikin Industries of Japan. This PCTFE resin has the same chemical structure and properties as the original Kel-F brand material. PCTFE 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 -400 degrees Fahrenheit to +400 degrees Fahrenheit.
