| For inventory control purposes product name may be followed by an X. Products labeled FEP 100 and FEP 100 X are equivalent and all information in this document is applicable to both. Typical Application Wire and cable insulation, small tubing and injection molded parts. DuPont Teflon ® FEP 100 is a melt-processible copolymer of tetrafluoroethylene and hexafluoropropylene without additives that meets the requirements of ASTM D 2116 type I. It offers the excellent combination of properties characteristic of Teflon ® fluoropolymer resins: non-ageing characteristics, chemical inertness, exceptional dielectric properties, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption, low flammability, performance at temperature extremes and excellent weather resistance. Teflon ® FEP 100 is a general purpose grade and is used in many different applications. It can be melt-extruded and is used for wire coating as primary insulation and, in certain cases, for cable jacketing. Cables insulated with Teflon ® FEP 100 have met the requirements of Underwriters’s Laboratory UL910 Steiner Tunnel tests for installation in plenums without metal conduits. Stress-crack resistance is an important element in establishing end-use performance. Extensive testing of wire and cable constructions is needed for definitive performance evaluation. 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.

| 1. Typical properties: these are not to be construed as specifications. |
| 2. The continuous service temperature is based on accelerated heat-aging tests, and represents the temperature at which tensile strength and ultimate elongation retains 50% of the original values, after 20 000 h thermal aging When considering the use of Teflon ® FEP at elevated temperatures especially in combination with mechanical, electrical or chemical exposure, preliminary testing should be done to verify suitability. |
