ETFE (kapa Ethylene tetraflurorethylene) ke polasetiki e thehiloeng ho fluorine, e nang le sebaka se phahameng sa ho qhibiliha le lik'hemik'hale tse babatsehang, tsa motlakase le tse phahameng tsa mahlaseli a kotsi.PTFE (kapa polytetrafluroethylene) ke fluorocarbon solid.Ho sebetsa joalo ka hydrophobic, ha ho metsi kapa lintho tse thehiloeng metsing tse metsi PTFE.PTFE e fokotsa khohlano, ho roala, 'me ka hona tšebeliso ea matla ea lipompo kaha e na le e 'ngoe ea li-coefficients tse tlase tsa khohlano khahlano le ntho efe kapa efe e tiileng.
Lisebelisoa tse tloaelehileng tse lokelang ho sebelisoa ho qobella pompo hape ke PTFE le ETFE polymers.
PTFE e entsoe ka liathomo tsa carbon le fluorine athe ETFE e hahiloe ka carbon, fluorine le hydrogen.Ho fana ka melemo ea ho sebelisa bobeli.
Matla a matla a ETFE a ka ba 38% ho feta PTFE, ho bolelang hore thepa ea ETFE e ka ba tlas'a maemo a thata a ho sebetsa ho feta molekane oa eona.
Ke ka lebaka leo lipompo tse ngata tsa lik'hemik'hale li fanoang ka ETFE kaha ke thepa e matla bakeng sa mokhoa oa ho bōpa ente oo ba fetang ho oona.
Leha ho le joalo PTFE e na le coefficient of friction ho karolo ea boraro ea ETFE e etsang hore e be e loketseng haholoanyane ha phallo e phahameng e hlokahala kaha e thusa ho fokotsa ho ferekana ha lipeipi Losses. Thermal properties of both materials are also a key differentiation... PTFE e ka fihla mocheso o phahameng oa 327c athe ETFE e ka fihla mocheso o phahameng oa 267c.
Mokhahlelo ona ke oa bohlokoa ha u khetha pompo e loketseng hantle;haeba sesebelisoa se hlokahalang ho pompeloa se ka fihla kae kapa kae haufi le mocheso ona ho molemo ho khetha PTFE kaha lisebelisoa ka bobeli li ntse li nolofala haufi le lintlha tsa tsona tse phahameng tsa mocheso.
Ho feta moo, PTFE e na le Limiting Oxygen Index (bonyane peresente ea mahloriso a oksijene moo polymer e tla chesa) e kholo ho feta 95% athe ETFE e pakeng tsa 30-36%, ho bolelang hore PTFE e lokela ho nkoa e le libakeng tse phahameng tsa oksijene.
