Tefzel 美国科慕 ETFE 750 乙烯四氟乙烯共聚物 管材级特氟龙

tefzel 750 gas igniter

generic name: 乙烯四氟乙烯共聚物(etfe) - 提供方: the chemourscompany

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.
typical end products
tefzel ™ etfe 750 fluoroplastic resin can be used for wire serviceat up to 200 °c (392 °f).tefzel ™ etfe 750 can also be used asinsulation for applications where customers need the basic benefitsof tefzel ™ together with increased flexibility and improvedretention of properties after aging at elevated
temperatures. flexibility is desirable for ease of handling duringmaintenance and repair procedures.
