Bukuli limakhudza kusankha kwa tepi yotentha kwambiri ya PTFE pakumangira jekeseni ndi ntchito zotsutsana ndi ndodo. Kusankha kotengera kutentha: ≤260 ° C kwa pulasitiki wamba (standard silicone PSA tepi, 0.13-0.18mm); 260-300 ° C kwa mapulasitiki opangira kutentha kwambiri monga PC, PA66, POM (zomatira za silicone zapamwamba, 0.18-0.25mm); 300-400 ° C ya PEEK, LCP, PPS pafupi ndi othamanga otentha (tepi yomatira imalephera; gwiritsani ntchito nsalu ya PTFE yopanda zomatira kapena filimu ya PFA). Kusankhidwa kozikidwa pazida: zida zomangira zimafunikira malo omasuka a PTFE; magalasi/mineral zodzazidwa ndi zinthu zimafuna heavy-ntchito 0.25mm+ kuvala zosagwira tepi; zowonjezera zowononga zimafuna zomatira zosagwirizana ndi mankhwala ndi gawo lapansi lowundana; ma static-sensitive application amafunikira tepi yotsutsa-static yakuda ya PTFE.

Nsalu yotentha kwambiri ya PTFE imapangidwa ndi kupaka PTFE pansalu yamphamvu kwambiri ya fiberglass, yomwe imapereka mphamvu zolimba, kukana kutentha, katundu wosagwira ndodo, kukana mankhwala, komanso kugundana kochepa. Ntchito zazikuluzikulu zikuphatikiza: kutumizira mafakitale (kutengera kutentha, kuphika chakudya, zowumitsa nsalu, kuyanika mapepala / filimu); nsalu zomangira zophatikizika komanso zomangira zomangira zowotcha; kuwotcherera makatani oteteza ndi ma jekete oteteza kutentha; magetsi galimoto ndi thiransifoma kutchinjiriza; kumanga zitsulo zotsetsereka ndi zothandizira mapaipi; kusefera kwa mankhwala ndi kusindikiza ma valve m'malo owononga. Kulimba kwamphamvu kwamphamvu kumatsimikizira kulimba pansi pa kukanidwa, kung'ambika, kusinthasintha mobwerezabwereza, komanso kupsinjika kwamakina kwapamwamba pamakina osiyanasiyana olemetsa.

Pa sintering, PTFE particles pa fiberglass nsalu kusungunuka pamwamba 327 ° C, kuwononga choyambirira apangidwe-unyolo lamellae ndi tinthu malire kupanga amorphous kusungunuka. Ikazizira, PTFE imakhazikikanso kukhala ma spherulites opangidwa ndi ma radially oriented lamellae, okhala ndi crystallinity kuyambira 50-70%. Kuzizira kumatsimikizira ungwiro wa kristalo: kuzizira pang'onopang'ono kumapereka crystallinity yapamwamba, ma spherulites akuluakulu, kuuma kwakukulu; kuzimitsa mwachangu kumapereka ma spherulites abwino komanso kusinthasintha bwino.
