Teflon FEP CJ 99

产品说明:
For inventory control purposes product name may be followed by an X.
Products labeled FEP CJ 99 and FEP CJ 99 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 CJ 99 is a melt-processible copolymer of tetrafluoroethylene and hexafluoropropylene without additives that meets the requirements of ASTM D 2116 type I.
Thanks to the unique combination of a Melt Flow Rate in the range of 9 g/10 min and MIT flexlife above 40 000 cycles, this resin offers both attractive processing speeds and high stress-rack resistance in addition to the excellent characteristics typical of Teflon fluoropolymer resins, such as non-ageing characteristics, chemical inertness, exceptional electrical properties, low flammability, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption and excellent weather resistance. The increased transparency of Teflon FEP CJ 99 will also allow better colourability.
Stress crack resistance is an important element in establishing end-use performance. Extensive testing of wire and cable constructions is required for definitive performance evaluation. Well-known and most comprehensive tests for stress rack resistance of wire and cable are mandrel wrap tests as described in the military specification MIL-W-22759 (aerospace) and ISO 6722/LV112 (automotive). Experience has shown that the MIT folding endurance or flex life test, based on ASTM D 2176, performed on a thin film of resin, gives a good correlation with stress crack resistance. Resins with a higher MIT flex life, perform better in the stress-crack resistance tests. Teflon FEP CJ 99 has a higher degree of stress crack resistance than most FEP resins with similar viscosity (MFR) and offers higher productivity than FEP resins with similar stress crack resistance (MIT). We recommend that for applications involving repeated thermal and flex cycling, specific tests on the final cable always should be undertaken. The MIT test results should be viewed as guide to comparative performance of the various grades of resin.
