ETFE (kapena Ethylene tetraflurorethylene) ndi pulasitiki yopangidwa ndi fluorine, yokhala ndi malo osungunuka kwambiri komanso mankhwala abwino kwambiri, magetsi komanso mphamvu zambiri zotsutsana ndi radiation.PTFE (kapena polytetrafluroethylene) ndi fluorocarbon solid.Kugwira ntchito ngati hydrophobic, osati madzi kapena zinthu zochokera m'madzi zonyowa PTFE.PTFE imachepetsa mikangano, kuvala komanso kugwiritsa ntchito mphamvu zamapampu chifukwa imakhala ndi imodzi mwazinthu zotsika kwambiri zolimbana ndi zolimba zilizonse.
Zida zodziwika bwino zomwe zingagwiritsidwe ntchito kulimbikitsanso mpope ndi ma polima a PTFE ndi ETFE.
PTFE imapangidwa kuchokera ku maatomu a carbon ndi fluorine pamene ETFE imapangidwa kuchokera ku carbon, fluorine ndi haidrojeni.Kupereka ubwino wogwiritsa ntchito zonsezi.
Mphamvu yamphamvu ya ETFE ikhoza kukhala yoposa 38% kuposa PTFE, kutanthauza kuti zinthu za ETFE zimatha kukhala ndi zovuta zogwirira ntchito kuposa mnzake.
Ichi ndichifukwa chake mapampu ambiri amaperekedwa mu ETFE chifukwa ndi chinthu champhamvu kwambiri pakupanga jekeseni komwe amadutsamo.
Komabe PTFE ili ndi coefficient of friction pa gawo limodzi mwa magawo atatu a ETFE kupangitsa kuti ikhale yoyenera kwambiri pamene kuthamanga kwapamwamba kumafunika chifukwa kumathandiza kuchepetsa mikangano ya chitoliro. pamene ETFE ikhoza kufika kutentha kwakukulu kwa 267c.
Gawo ili ndilofunika kwambiri posankha pampu yoyenera;ngati ntchito yofunikira kuti ipope imatha kufika paliponse pafupi ndi kutentha kumeneku ndi bwino kusankha PTFE monga zipangizo zonse zimakhala zofewa pafupi ndi malo awo otentha kwambiri.
Kuwonjezera apo, PTFE ili ndi Limiting Oxygen Index (yochepa peresenti ya oksijeni yomwe polima idzawotchedwa) yoposa 95% pamene ETFE ili pakati pa 30-36%, kutanthauza kuti PTFE iyenera kuganiziridwa m'madera apamwamba a okosijeni.
