ETFE 美国科慕750 电子绝缘

dupont™ tefzel ® fluoropolymer resins offer mechanical strengthand toughness along with resistance to heat and chemicals. inaddition, they provide easy processing, high specific dielectricstrength, and a low coefficient of friction. for these reasons,tefzel ® resins are widely used to make compact wire and cableconstructions that provide long, reliable service in demandingenvironments.
tefzel ® 750 retains the traditional characteristics of tefzel ®resins while providing some new property advantages, includingincreased flexibility and improved retention of properties afteraging at elevated temperatures, higher limiting oxygen index, andlong-term service life at higher temperatures than other tefzel ®resins.
underwriters laboratories, inc. (ul) has rated wire insulated withtefzel ® 750 (10 mil for 600v, 6 mil for 300v) for service inappliances at a maximum continuous operating temperature of 200°c(392°f). this rating was determined under the guidelines of ulsubject 758 for appliance wiring material. upper servicetemperatures for other applications should be determined under theguidelines for those applications. temperature ratings may not bethe same as the rating for appliance wire because the testprocedures are different.
