杜邦Tefzel氟聚合物树脂不仅具有机械强度和韧性,还具有耐热性和耐化学性。此外,它们提供了易于加工、高比介电强度和低摩擦系数。由于这些原因,Tefzel树脂被广泛用于制造紧凑的电线和电缆结构,在苛刻的环境中提供长期、可靠的服务。Tefzel 750保留了Tefzel树脂的传统特性,同时提供了一些新的性能优势,包括在高温老化后提高灵活性和更好的性能保持性、更高的极限氧指数和在更高温度下的长期使用寿命。美国保险商实验室有限公司(UL)的额定电线与Tefzel 750绝缘(600V为10 mil,300V为6 mil),可在200°C(392°F)的最大连续工作温度下使用。该等级是根据UL第758号标准关于电器布线材料的指南确定的。其他应用的最高工作温度应根据这些应用的指南确定。温度额定值可能与电器导线的额定值不同,因为测试程序不同。 DuPont™ Tefzel ® fluoropolymer resins offer mechanical strength and toughness along with resistance to heat and chemicals. In addition, they provide easy processing, high specific dielectric strength, and a low coefficient of friction. For these reasons, Tefzel ® resins are widely used to make compact wire and cable constructions that provide long, reliable service in demanding environments. Tefzel ® 750 retains the traditional characteristics of Tefzel ® resins while providing some new property advantages, including increased flexibility and improved retention of properties after aging at elevated temperatures, higher limiting oxygen index, and long-term service life at higher temperatures than other Tefzel ® resins. Underwriters Laboratories, Inc. (UL) has rated wire insulated with Tefzel ® 750 (10 mil for 600V, 6 mil for 300V) for service in appliances at a maximum continuous operating temperature of 200°C (392°F). This rating was determined under the guidelines of UL Subject 758 for appliance wiring material. Upper service temperatures for other applications should be determined under the guidelines for those applications. Temperature ratings may not be the same as the rating for appliance wire because the test procedures are different. |
