PTFE olugoye olw’ebbugumu eringi lukuuma okuziyiza amasannyalaze okulungi ennyo okuva ku -180°C okutuuka ku 260°C: volume resistivity >1013 Ω·cm ku 200°C, dielectric constant stable ku 2.0-2.1. Waggulu wa 260°C, PTFE egonvuwa, evunda waggulu wa 327°C, n’efiirwa insulation enkalakkalira. Wansi wa 0°C, insulation etereera naye okusiiga kufuuka brittle. Sigala mu 260°C okusobola okukola obulungi.

Olugoye lwa PTFE olw’ebbugumu eringi (PTFE-coated fiberglass) lulungi nnyo ku misipi egy’okutambuza emmere olw’okugumira ebbugumu lya 260°C, -70°C okukyukakyuka mu nnyonta, kungulu okutakwata, n’okugoberera FDA. Ebikulu ebikozesebwa: oveni z’emigaati (bisikiiti, omugaati, pizza), ebyuma ebitambuza emmere ebisiike, layini ezinyogoza ssweeta, emikutu egy’okufumbisa, ebisiba ebbugumu, n’okuzinga roller. Kikendeeza ku kasasiro n’obudde bw’okuyonja.

Okukola kalenda – okunyiga olugoye olusiigiddwa PTFE wakati w’ebiwujjo by’endabirwamu ebibuguma ku 360-380°C – kikyusa nnyo enkula y’okungulu, eby’obugagga by’okufulumya, obutayita mu mazzi, n’enkola y’ebyuma. Kikendeeza ku bukaluba okuva ku Ra 0.5-1.0 μm okutuuka ku <0.05 μm, kisiba ebituli bya ppini, kitereeza okuziyiza okwambala, naye kikendeeza ku maanyi g’okukutuka n’okukyukakyuka. Kyetaagisa nnyo ku layers ezifulumya n’okuziyiza amasannyalaze.

Olugoye lwa PTFE olw’ebbugumu eringi n’olugoye lwa silicone byombi bikozesa olugoye lwa fiberglass nga base naye nga byawukana mu bintu ebisiiga (PTFE resin vs silicone rubber). PTFE esinga mu butakwata, okugumira okwambala, n’okugumira eddagala okutuuka ku 260°C. Olugoye lwa silicone luwa okukyukakyuka okw’ekika ekya waggulu, okuziyiza amasannyalaze, n’okuziyiza omuliro (okutuuka ku 230°C). Londa okusinziira ku ky’olina okukulembeza.

PTFE olugoye olw’ebbugumu eringi (PTFE membrane material) lwe lusinga okulondebwa mu nzimba y’okusika. Ebirungi ebikulu: obulamu obw’ebweru obw’emyaka 30+, okweyonja kungulu (amazzi g’enkuba ganaaza obucaafu), okutambuza ekitangaala ekigonvu (6-13%), ekipimo ky’omuliro ekya Class A, n’amaanyi agalinga ag’ekyuma wansi wa kkiro 1.5/m2. Ekozesebwa mu bisaawe, ebisaawe by’ennyonyi, n’ebizimbe ebimanyiddwa ennyo mu nsi yonna.

Okufukirira kwa PTFE tekukoma ku lugoye lwa fiberglass. Ekiwandiiko kino kyanjula 7 alternative substrates – aramid, carbon fiber, PBI, porous metal, graphite, asbestos (phased out), ne ceramic fillers – n’enkola yaabwe, ebirungi, obuzibu, n’okukozesebwa okukulu.

Ekiwandiiko kino kinnyonnyola lwaki olugoye lwa fiberglass olutaliimu alkali lwe lusinga okwettanirwa olugoye olwa PTFE olw’ebbugumu eringi. Kikwata ku kukwatagana kw’eddagala okuyita mu bikozesebwa ebiyunga silane n’ebintu ebikulu eby’omubiri nga okunyweza ebbugumu, okunyweza mu bipimo, n’okuziyiza okukulukuta – okukakasa okukola okumala ebbanga eddene mu mbeera enkambwe.
