Indwangu ye-PTFE enezinga eliphezulu lokushisa eliphezulu isetshenziswa kabanzi embonini yamakhemikhali ezintweni eziyisikhombisa ezibalulekile: ama-flange gaskets namapayipi afakwa ngaphakathi (amelana nama-acids aqinile/ama-alkali), i-reactor kanye ne-tank linings (ivimbela ukugqwala kwensimbi, ukuhlanzeka kalula), izikhwama zokuhlunga zegesi egqwalayo (efika ku-260°C), ukunwetshwa kokubola kwe-corrosion, ukunwetshwa kokukhishwa kwendwangu yensimbi ukubumba okuyinhlanganisela, kanye nokusonga kokufakwa kukagesi/okushisayo. I-FDA ne-UL amamaki ayatholakala.

Ama-ejenti wokuqedela ongaphezulu asetshenziswa endwangu ye-fiberglass ngaphambi kokunameka kwe-PTFE abalulekile ekusebenzeni kokugcina kwendwangu yezinga lokushisa eliphezulu ye-PTFE. I-Organosilane coupling agents idala amabhuloho amamolekyuli phakathi kwe-inorganic glass fiber kanye ne-organic PTFE, ekhulisa amandla ekhasi ukusuka ku-<2 N/cm ukuya ku-4-8+ N/cm. Ukwelashwa okufanele futhi kuthuthukisa ukumelana nokushisa (260°C+), ukusebenza kwe-dielectric, nokumelana namakhemikhali. Indwangu enganakiwe iholela ekuqhekekeni, ekubhibhizeni, nempilo yesevisi emfushane.
