PTFE nembanemba ndi woonda, kwambiri porous filimu amene amachita ngati mtheradi retentive nembanemba.Chikhalidwe chawo chokhala ndi hydrophobic chimapangitsa PTFE nembanemba kukhala yabwino kwa ntchito monga kusefa mpweya, aerosols amadzimadzi, kuteteza mapampu a vacuum, kapena matanki oyimitsa mpweya wosabala.PTFE ndiyomwe imagwiritsa ntchito zosungunulira zamphamvu kwambiri, ma asidi amphamvu ndi maziko ndipo itha kugwiritsidwa ntchito pofotokozera zosungunulira ndi HPLC prep.
Ma membrane a PTFE amapezeka osathandizidwa komanso othandizira.PTFE nembanemba yokhala ndi laminated polypropylene web support ku mbali imodzi imapereka mawonekedwe owongolera.Zoletsa za Chemical ndi matenthedwe zimayikidwa ndi kuthandizira.
Chimodzi mwazofunikira pakusankha kwa membrane ndikuti mukufuna nembanemba yomwe ndi Hydrophobic kapena Hydrophilic.Apa titanthauzira mawu awa, komanso kupereka zitsanzo za zida za membrane ndi ntchito zamitundu yonseyi.Hydrophilic kwenikweni amatanthauza "kukonda madzi."Mamembala a hydrophilic amakopa madzi, ndipo potero amakankhira kutali mamolekyu ena kuti alole madzi kulowa mu nembanembayo.Izi zimapangitsa kuti zonyansa zikhale kutali ndi nembanemba zomwe zimalola kuti ikhale yoyera komanso kugwira ntchito kwa nthawi yayitali.Chifukwa cha izi, ma membrane a hydrophilic ndi oyenerera kwambiri kugwiritsa ntchito zamankhwala komanso kuyesa kwachilengedwe.Kumbali ina, Hydrophobic, kwenikweni amatanthauza "kuopa madzi."
Ma nembanembawa amatsekereza njira yamadzi ndipo amagwiritsidwa ntchito kwambiri popanga madzi olekanitsa ndi zinthu zina, monga mpweya wotulutsa mpweya.Nayi tebulo lothandizira lomwe limafananiza zida za membrane ndi ntchito zomwe zimagwiritsidwa ntchito nthawi zambiri paza hydrophilic ndi hydrophobic:
