PTFE olugoye olw’ebbugumu eringi (PTFE-coated fiberglass) lye ssengejjero ery’omutindo ogwa waggulu eri embeera ezisukkiridde: okuggya enfuufu ya ggaasi w’omukka (seminti, okwokya kasasiro, bboyiyira z’amanda okutuuka ku 260°C), okusengejja amazzi agakulukuta (asidi, alkali, amafuta), okusengejja emmere/eddagala eritaliimu buwuka, n’okusengejja ebisenge ebiyonjo ebya HEPA. Ekitundu ekitali kikwata kiziyiza enfuufu okucake era kisobozesa okwanguyirwa okuyonja. Grades ezikoleddwa mu membrane-laminated zituuka ku bucaafu obutono ennyo.

PTFE olugoye olw’ebbugumu eringi lukuuma okuziyiza amasannyalaze okulungi ennyo okuva ku -180°C okutuuka ku 260°C: obuziyiza obunene >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.

Ebirungo ebimaliriza kungulu ebisiigibwa ku lugoye lwa fiberglass nga tebannaba kusiiga PTFE bikulu nnyo mu kukola olugoye olw’ebbugumu eringi olwa PTFE olusembayo. Ebirungo ebiyunga organosilane bikola ebibanda bya molekyu wakati wa fiber y’endabirwamu etali ya kiramu ne PTFE ey’obutonde, ne bitumbula amaanyi g’ebikuta okuva ku <2 N/cm okutuuka ku 4-8+ N/cm. Okujjanjaba obulungi era kwongera ku bugumu (260°C+), okukola kwa dielectric, n’okuziyiza eddagala. Olugoye olutali lulongooseddwa luvaako okukutuka, okubumbulukuka, n’okuwangaala okumpi.

Omusono gw’okuluka fiberglass – ogwa bulijjo, twill, oba satin – gukosa nnyo eby’obugagga by’olugoye olw’ebbugumu eringi mu PTFE. Satin weave ekuwa amaanyi agasinga okukutuka (2-3x plain) n’okukyukakyuka, ekirungi ennyo mu kubeebalama mu ngeri ey’amaanyi. Okuluka okwa bulijjo kuwa okunyweza okusinga obulungi mu bipimo n’okunyweza ebikuta, ebisaanira okukozesebwa mu ngeri etali ya kukyukakyuka. Twill egerageranya eby’obugagga byonna okukozesebwa abantu bonna.

Okusiiga ekimu ku lugoye lwa PTFE olw’ebbugumu eringi kisalibwawo ensonga nnya: okukola okusiiga (obunene bw’obutundutundu 0.15-0.35 μm, obuzito, ebikalu), enkola y’okusiiga & okusiiga (okusiiga ekyuma ekisinga okwettanirwa olw’obumu), omutindo gwa substrate (enkola y’okuluka, nga tebannaba kulongoosa), n’embeera y’okufulumya (20-25°C, <60% RH). Enkola ya Dip + blade combined egerageranya okuyingira n’obugonvu bw’okungulu.

Okwoza n’okuddaabiriza obulungi kwongera ku bulamu bw’olugoye lwa PTFE olw’ebbugumu eringi. Okwoza ng’omaze okukozesa n’oluvannyuma lw’okunyogoza. Kozesa bbulawuzi ennyogovu, eby’okunaaba ebitaliimu oba omwenge ku mabala. Tokozesangako asidi/alkali ez’amaanyi, bleach, oba ebyuma ebisenya. Okusiiga amafuta ga silikoni buli kiseera kikendeeza ku kwambala. Goberera ebiragiro bino okutangira ebizigo okwonooneka.

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.

Olugoye lwa PTFE olw’ebbugumu eringi luwa obugumu obw’enjawulo obw’eddagala, okugumira asidi ez’amaanyi, alkali, ebizimbulukusa ebiramu, ne ggaasi ezivunda. Ekitundu kino kiraga mu bujjuvu ebintu byayo ebigumira, obuzibu (ebyuma bya alkali ebisaanuuse, ebirungo ebikola fluorinating eby’amaanyi), n’ensonga enkulu nga ebbugumu, okusengejja, n’okunyigirizibwa kw’ebyuma.

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 ebifaananyi, 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 enzibu.
