dupont™ tefzel ® fluoropolymer resins offer mechanicalstrengthand toughness along with resistance to heat and chemicals.inaddition, they provide easy processing, high specificdielectricstrength, and a low coefficient of friction. for thesereasons,tefzel ® resins are widely used to make compact wire andcableconstructions that provide long, reliable service indemandingenvironments.
tefzel ® 750 retains the traditional characteristics of tefzel®resins while providing some new property advantages,includingincreased flexibility and improved retention of propertiesafteraging 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 insulatedwithtefzel ® 750 (10 mil for 600v, 6 mil for 300v) for serviceinappliances at a maximum continuous operating temperature of200°c(392°f). this rating was determined under the guidelines ofulsubject 758 for appliance wiring material. upperservicetemperatures for other applications should be determinedunder theguidelines for those applications. temperature ratings maynot bethe same as the rating for appliance wire because thetestprocedures are different.
