For inventory control purposes product name may be followed by an X. Products labeled FEP 9302 and FEP 9302 X are equivalent and all information in this document is applicable to both. Typical Application Tubes, piping, linings, bellows, valves and other components for the chemical industry. Jackets for Wire and Cable applications demanding a high degree of stress crack resistance. DuPont Teflon ® FEP 9302 is a melt-processible copolymer of tetrafluoroethylene and hexafluoropropylene without additives that meets the requirements of ASTM D 2116 type IV. It offers the excellent combination of properties characteristic of Teflon ® fluoropolymer resins: non-ageing characteristics, chemical inertness, exceptional dielectric properties, low flammability, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption and excellent weather resistance. Teflon ® FEP 9302 is used in the chemical industry for applications such as chemical linings, bellows, valve components, pipes and tubing. In demanding Wire and Cable applications, requiring a very high degree of stress crack resistance, it can be used as a material for jacketing. Thanks to its combination of viscosity and stress crack resistance, it can be processed at faster rates and higher extrusion line speeds than many FEP grades with comparable stress crack resistance performance. Stress crack resistance is an important element in establishing end-use performance. Experience shows that the MIT folding endurance or flex life test, performed on a thin film of resin, has established a good correlation with extensive cable testing. The higher the MIT flex life, the higher the stress-crack resistance of the resin. MIT test results should be viewed as a guide to comparative performance of the various grades of resin. We recommend that for applications involving repeated thermal and flex cycling, specific tests on the final cable always should be undertaken.
