出于库存控制目的,产品名称后面可以跟一个X。标记为FEP 9302和FEP 9302 X的产品是等效的,本文件中的所有信息都适用于这两者。化工行业的典型应用管道、管道、衬里、波纹管、阀门和其他部件。用于要求高应力抗裂性的电线和电缆应用的护套。杜邦特氟隆FEP 9302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第四类的要求。它提供了特氟隆氟聚合物树脂的优良性能组合:无老化特性、化学惰性、优异的介电性能。低可燃性、耐热性、韧性和柔韧性、低摩擦系数、不粘特性、可忽略的吸湿性和优异的耐候性。Teflon FEP 9302用于化学工业,如化学衬里、波纹管、阀门部件、管道和管道。在要求很高的电线和电缆应用中,它需要很高的抗应力开裂能力,可以用作护套材料。由于它的粘度和应力抗裂性的结合,它可以在更快的速度和更高的挤出生产线速度比许多FEP等级具有相当的应力抗裂性能。应力抗裂性是确定最终使用性能的重要因素。经验表明,在树脂薄膜上进行的MIT耐折性或弯曲寿命试验与广泛的电缆试验建立了良好的相关性。MIT的弹性寿命越高,树脂的应力开裂抗力越高。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。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。另请参见杜邦公告“电线和电缆应用的等级选择器”。 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.
