I-ETFE (okanye i-Ethylene tetraflurorethylene) yiplastiki esekelwe kwi-fluorine, exhotywe ngeqondo eliphezulu lokunyibilika kunye nekhemikhali egqwesileyo, umbane kunye namandla aphezulu okumelana nepropathi ye-radiation.PTFE (okanye i-polytetrafluroethylene) yinto eqinileyo ye-fluorocarbon.Ukusebenza njenge-hydrophobic, hayi amanzi okanye izinto ezisekelwe emanzini zimanzi i-PTFE.I-PTFE yehlisa ukukhuhlana, ukunxiba kwaye ngenxa yoko ukusetyenziswa kwamandla eempompo njengoko ineyona coefficients isezantsi yokukhuhlane ngokuchasene nayo nayiphi na into eqinileyo.
Ezona mathiriyeli zixhaphakileyo eziza kusetyenziselwa ukunyanzelisa kwakhona impompo yi-PTFE kunye neepolima ze-ETFE.
I-PTFE yakhiwe ngekhabhoni kunye neeathom zefluorine ngelixa i-ETFE yakhiwe ngekhabhoni, ifluorine kunye nehydrogen.Ukunika inzuzo ekusebenziseni zombini.
Amandla obunzima be-ETFE anokuba yi-38% enkulu kune-PTFE, oku kuthetha ukuba izinto ze-ETFE zinokuthi zithotyelwe phantsi kweemeko zokusebenza ezinzima kunomlingani wayo.
Yiyo loo nto uninzi lweempompo zemichiza zibonelelwa kwi-ETFE njengoko iyimathiriyeli eyomeleleyo yenkqubo yokubumba inaliti abahamba ngayo.
Nangona kunjalo i-PTFE ine-coefficient of friction kwisinye kwisithathu se-ETFE iyenza ukuba ifaneleke ngakumbi xa ukuhamba okuphezulu kufunwa njengoko inceda ukunciphisa ukukhuhlana kombhobho. kanti i-ETFE inokufikelela kubushushu obuphezulu be-267c.
Eli nqanaba libaluleke kakhulu xa ukhetha impompo efanelekileyo;ukuba isicelo esifunekayo ukumpontshwa sinokufikelela naphina kufutshane nala maqondo obushushu kungcono ukhethe i-PTFE njengoko zombini imathiriyeli iya ithambile kufutshane neendawo zazo zobushushu eziphezulu.
Ngaphezu koko, i-PTFE ine-Limiting Oxygen Index (ubuncinci bepesenti yoxinaniso lwe-oksijini apho i-polymer iya kutshisa) ngaphezu kwe-95% ngelixa i-ETFE iphakathi kwe-30-36%, oku kuthetha ukuba i-PTFE kufuneka ithathelwe ingqalelo kwiindawo eziphezulu ze-oksijini.
