I-PTFE inwebu yifilimu ebhityileyo, enemingxuma ephezulu esebenza njengenwebu ebambekayo ngokupheleleyo.Ubume bazo bendalo be-hydrophobic benza ukuba ii-membrane ze-PTFE zilungele usetyenziso olufana neegesi zokucoca, ii-aerosols ezinamanzi, iimpompo zokufunxa ezikhuselayo, okanye iitanki zokuvuthela ezinyumba.I-PTFE ayisebenzi kwizinyibilikisi ezininzi ezinobundlobongela bekhemikhali, iiasidi ezomeleleyo kunye neziseko kwaye ingasetyenziselwa ukucaciswa kwesinyibilikisi kunye nolungiselelo lwesampulu ye-HPLC.
Iinwebu ze-PTFE ziyafumaneka azixhaswa kwaye zixhaswa.Iinwebu ze-PTFE ezinenkxaso yewebhu yepolypropylene elaminethiweyo kwelinye icala ibonelela ngeempawu zokuphatha eziphuculweyo.Ukulinganiselwa kweekhemikhali kunye ne-thermal kubekwe ngokuxhaswa.
Enye yeempawu ezibalulekileyo ekukhetheni inwebu kukuba ufuna inwebu eyiHydrophobic okanye iHydrophilic.Apha sizakuchaza la magama, kunye nokubonelela ngemizekelo yemathiriyeli yenwebu kunye nezicelo zazo zombini iindidi.I-Hydrophilic ngokoqobo ithetha "ukuthanda amanzi."Iimbrane zeHydrophilic ziya kutsala amanzi, kwaye kwinkqubo zityhala ezinye iimolekyuli ukuze zivumele ukufikelela kwamanzi kwinwebu.Oku kugcina ungcoliseko kude ne-membrane ivumela ukuba ihlale icocekile kwaye isebenze ixesha elide.Ngenxa yolu phawu, iimbrane ze-hydrophilic zifaneleke ngakumbi kwizicelo zonyango kunye novavanyo lwebhayoloji.Kwelinye icala, iHydrophobic, ngokoqobo ithetha “ukoyika amanzi.”
Ezi membrane ziya kuvala ukudlula kwamanzi kwaye ziqhele ukusetyenziswa kwizicelo ezibandakanya ukwahlulwa kwamanzi kwezinye izinto, ezinje ngeegesi zokukhupha umoya.Nantsi itheyibhile eluncedo ethelekisa imbrane imathiriyeli kunye nokusetyenziswa okuqhelekileyo kwiipropathi ze-hydrophilic kunye ne-hydrophobic:
