Indwangu ye-PTFE ephezulu yokushisa (i-PTFE-coated fiberglass) inokumelana nokushaqeka okuhle kakhulu okushisayo ngaphakathi kwebanga lokusebenza elijwayelekile elingu -70°C kuya ku-260°C. Ingakwazi ukubekezelela ukuhamba ngebhayisikili okusheshayo kwezinga lokushisa, isb, ukusuka ku- -50°C efrijini ukuya emshinini wokunyathelisa oshisayo ongu-260°C. Amabanga e-Premium aze asinde ekupholiseni kungazelelwe ukusuka ku-260°C ukuya ku-10°C emanzini. Nokho, ukushaqisa okokusebenza emazingeni okushisa angaphezu kuka-300°C (eduze kwendawo yokuncibilika ye-PTFE's 327°C) kuzodala ukuqhekeka kanye nokuncibilika ngokushesha. I-fiberglass substrate inikeza ukuzinza kwe-dimensional; ukunamathela kwe-PTFE kuyisici esikhawulelayo.

Indwangu ye-PTFE enezinga eliphezulu lokushisa eliphezulu isetshenziswa kakhulu embonini yamakhemikhali ezintweni eziyisikhombisa ezibalulekile: ama-flange gaskets namapayipi afakwa ngaphakathi (amelana nama-acids aqinile/ama-alkali), i-reactor 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.

Indwangu ye-PTFE enezinga eliphezulu lokushisa izinzile kufika ku-300°C, kodwa emlilweni iyabola futhi ikhiphe amagesi anobuthi obukhulu: i-hydrogen fluoride (HF) (i-corrosive, pulmonary edema) ne-perfluoroisobutylene (PFIB) (ayinambala, ayinaphunga, ~10x ubuthi obungaphezu kwe-phosgene, i-nodo). Futhi i-carbon monoxide, izinsalela ze-PFOA, kanye ne-trace dioxins. Izifihla-buso zentuthu ezivamile azisebenzi; sebenzisa izisetshenziswa zokuphefumula ezizimele (SCBA). Izimpawu zingase zibambezeleke.

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.

Ukuhlanzwa nokugcinwa ngendlela efanele kwandisa impilo yendwangu ye-PTFE enezinga eliphezulu lokushisa. Hlanza ngemva kokusetshenziswa nangemuva kokupholisa. Sebenzisa amabhulashi athambile, okokuhlanza okungathathi hlangothi, noma utshwala ukuze uthole amabala. Ungalokothi usebenzise ama-asidi/ama-alkali aqinile, i-bleach, noma ama-metal scrapers. Ukugcoba uwoyela we-silicone njalo kunciphisa ukuguga. Landela le mihlahlandlela ukuze ugweme ukulimala kokumboza.
