Indwangu ye-PTFE enezinga eliphezulu lokushisa eliphezulu nendwangu ye-silicone kokubili kusebenzisa indwangu ye-fiberglass njengesisekelo kodwa ihlukile ezintweni zokumboza (i-PTFE resin vs irabha ye-silicone). I-PTFE iphumelela kakhulu ekungabambeni, ukumelana nokugqoka, kanye nokumelana namakhemikhali kufika ku-260°C. Indwangu ye-Silicone inikeza ukuguquguquka okuphakeme, ukufakwa kukagesi, nokumelana nomlilo (kufika ku-230°C). Khetha ngokusekelwe kokubalulekile kwakho.

Indwangu ye-PTFE enezinga eliphezulu lokushisa inikeza ukumelana kwamakhemikhali okukhethekile, imelana nama-asidi aqinile, ama-alkali, izinyibilikisi eziphilayo, namagesi abolayo. Lesi sihloko sichaza ngezinto ezimelana nayo, imikhawulo (izinsimbi ze-alkali ezincibilikisiwe, ama-ejenti anamandla e-fluorinating), nezici ezibalulekile ezifana nezinga lokushisa, ukugxilisa ingqondo, nokucindezeleka komshini.

Ukufakwa kwe-PTFE akugcini nje ngendwangu ye-fiberglass. Lesi sihloko sethula ama-substrates angu-7 ahlukile - i-aramid, i-carbon fibre, i-PBI, insimbi enezimbotshana, i-graphite, i-asbestos (ikhishiwe), kanye nezigcwalisi ze-ceramic - nezici zazo zenqubo, izinzuzo, imikhawulo, kanye nezicelo ezibalulekile.

Lesi sihloko sichaza ukuthi kungani indwangu ye-fiberglass engena-alkali iyisisekelo esincanyelwayo sendwangu ye-PTFE enezinga lokushisa eliphezulu. Ihlanganisa ukubopha kwamakhemikhali ngama-ejenti ahlanganisayo we-silane kanye nezakhiwo ezibalulekile zomzimba njengokuzinza kwe-thermal, ukuzinza kwe-dimensional, nokumelana nokugqwala - iqinisekisa ukusebenza okuhlala isikhathi eside ezindaweni ezinokhahlo.

Njengomkhiqizi ochwepheshe wezindwangu zokushisa okuphezulu kwe-PTFE, i-Jiangsu Aokai New Materials yabelana nawe ngolwazi olufanele lomkhakha. I-Edge warping kanye nokuwa kumatheyipu okushisa aphezulu e-PTFE akuvamile ukubangelwa isici esisodwa, kodwa umphumela wemiphumela ehlanganisiwe yokukhetha okungalungile kwe-tape,

I-Jiangsu Aokai New Material, umkhiqizi ohamba phambili wendwangu ye-PTFE eshisa kakhulu, wabelana ngemininingwane yobungcweti: Imigqa evundlile kanye nomehluko wombala wephethini yamafu endwangu ye-PTFE enezinga eliphezulu lokushisa empeleni kuwukubonakaliswa kokujiya okungalingani nokusabalaliswa kwengcindezi. Ukukhiqiza
