Olugoye olwa PTFE olw’ebbugumu eringi (PTFE-coated fiberglass) lulina obuziyiza obubi obw’okunyiga kubanga ekitundu kya fiberglass mu butonde kibeera kikutuse. Emifaliso emigonvu (0.08mm) giwangaala ebikumi n’ebikumi n’enkumi z’okuzinga; ebika ebizito (>0.25mm) byatika oluvannyuma lw’amakumi. Satin weave esinga okuluka okwa bulijjo. Ku kubeebalama okutambula obutasalako, lowooza ku firimu ya PTFE enkalu oba olugoye olukoleddwa mu aramid-based mu kifo ky’ekyo.

PTFE high-temperature tape eweereza PV amakolero mu mirimu ebiri egy’enjawulo: enkola consumable (okuziyiza EVA overflow adhesion ku laminators, solder mask) n’obulamu obuwanvu insulation (busbar wrap, junction box fixation). Okusobola okukozesebwa munda enkalakkalira, obutambi bulina okuyita mu IEC 61215: ebbugumu ery’obunnyogovu 1000-2000h, UV, enzirukanya y’ebbugumu (-40°C okutuuka ku +85°C), nga silikoni PSA n’okukendeera <1%.

PTFE olugoye olw’ebbugumu eringi (PTFE-coated fiberglass) lukozesebwa nnyo mu kukuba engoye n’okusiiga langi ku misipi egy’okukuba ebitabo egy’okutambuza ebbugumu (180-230°C), ebibikka ku mmeeza ezikuba ku ssirini, emisipi egy’akatimba egy’okukala, emisipi gy’ekyuma ekifuyira, n’okuzinga roller. Obugulumivu bwayo obutakwata buziyiza ebisigadde bya yinki/ebisiiga, okukendeeza ku budde bw’okuyonja n’okutumbula omutindo gw’olugoye. Emisipi egitakoma egitalina musonno gisobozesa okufulumya obutasalako.

PTFE high-temperature tape essiddwa ku bbugumu-siba ebiso n’okusiba emiguwa etuwa emiwendo ena emikulu: okuziyiza okusaanuuka obuveera okunywerera (okumalawo downtime), okukuuma okusiba okufa okw’ebbeeyi, homogenizes ebbugumu / puleesa okusobola okusiba obutakyukakyuka, era okukendeeza firimu okusikagana. Teepu eriko fiberglass-backed (0.13-0.25 mm) nga eriko silicone PSA (≥260°C) ye kirungi. Anti-static black tape ku layini ez’amaanyi.

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. Grade 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.

Eky’obugagga ekiziyiza omukka gw’amazzi ekya PTFE adhesive tape kisalibwa okusinga okusinziira ku buzibu bw’okusiiga (micropores, microcracks, fiber wicking) okusinga PTFE’s intrinsic hydrophobicity. Pure PTFE film egaba WVTR eya wakati yokka. Okusiiga okw’emitendera mingi n’okujjuza lamellar (mica, glass flakes) bikola ekikolwa kya labyrinth, ekikendeeza nnyo ku kutambuza omukka. Ku kusiba obunnyogovu obungi, laga ebizigo ebizitowa.

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’okufumba emigaati (bisikiiti, omugaati, pizza), ebyuma ebitambuza emmere esiike, layini ezinyogoza ssweeta, emikutu egy’okufumbisa, ebisiba ebbugumu, n’okuzinga roller. Kikendeeza ku kasasiro n’obudde bw’okuyonja.

Obuziyiza okuseeyeeya (creep resistance) bwa PTFE high-temperature adhesive tape wansi w’omugugu ogutakyukakyuka ogw’ekiseera ekiwanvu (naddala ku 200-260°C) busalibwawo ensonga bbiri: silicone PSA crosslink density (okusalasala okw’amaanyi kuziyiza okukulukuta) n’ekika kya substrate (fiberglass-reinforced PTFE resists cold creep; pure PTFE film creeps). Uncrosslinked adhesive eremererwa mangu ku bbugumu eringi. Layers ezisiiga enzito zongera ku bulabe bw’okuseeyeeya.

Ku PTFE high-temperature tape ekozesebwa mu abrasive sliding friction applications, standard obutakwata n’okuziyiza ebbugumu tebimala. Emisingi emikulu egy’okulonda: Okufiirwa kw’okusiiga kwa taber (<15 mg/1000 cycles), okusiiga kwa PTFE okukyusiddwa okujjuza (carbon/graphite/MoS2), data ya kkomo lya PV, amaanyi ga substrate (≥200 N/cm), n’obukaluba bw’okungulu kw’okugatta (Ra 0.2-0.4 μm). Okukuuma obulungi ku mbiriizi n’okukwatagana mu bujjuvu kikulu nnyo okusobola okuwangaala.
