出于库存控制目的,产品名称后面可以跟一个X。标记为FEP CJ 99和FEP CJ 99 X的产品是等效的,本文件中的所有信息都适用于这两者。典型应用电线电缆绝缘,小管道和注塑件。杜邦特氟隆FEP CJ 99是一种不含添加剂的四氟乙烯和六氟丙烯的熔融加工共聚物,符合ASTM D 2116 I型的要求。由于熔融流速在9 g/10 min范围内的独特组合和超过40000个循环的MIT弹性寿命,该树脂提供了有吸引力的加工速度和高性能。GH耐应力机架除了具有典型的聚四氟乙烯氟聚合物树脂的优良特性外,还具有非老化特性、化学惰性、特殊的电气特性、低可燃性、耐热性、韧性和柔韧性、低摩擦系数、不粘特性、可忽略的吸湿性。具有良好的耐候性。特氟隆FEP CJ 99透明度的提高也将使其具有更好的着色性。应力抗裂性是确定最终使用性能的重要因素。为了确定性能评估,需要对电线和电缆结构进行广泛的测试。众所周知,最全面的电线和电缆应力架电阻试验是军用规范MIL-W-22759(航空航天)和ISO 6722/LV112(汽车)中所述的芯轴缠绕试验。经验表明,基于ASTM D 2176,在树脂薄膜上进行的MIT耐折性或弯曲寿命试验与应力开裂性能有很好的相关性。具有较高的MIT弹性寿命的树脂,在应力开裂试验中表现更好。与大多数粘度相近的FEP树脂(MFR)相比,Teflon FEP CJ 99具有更高的抗应力开裂性能,并且比具有相同抗应力开裂性能(MIT)的FEP树脂具有更高的生产率。我们建议,对于涉及重复热循环和弯曲循环的应用,应始终对最终电缆进行特定测试。麻省理工学院的测试结果应被视为不同等级树脂比较性能的指南。 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. |
