Rolled PTFE tape esobola okukulaakulanya interlayer adhesion (blocking) n’okutambuza adhesive mu kiseera ky’okutereka okumala ebbanga eddene. Ebivaako: PTFE film elastic memory ne silicone PSA creep wansi wa puleesa/ebbugumu. Okuziyiza: gradient winding tension (ebweru tight, inner loose) nga okola, nga kwogasse n’okufulumya okusiiga ku ludda olutali lwa kwesiiga. Teeka ku -15°C okutuuka ku 40°C, 30-70% RH, mu bbanga ku racks, kyusakyusa emizingo buli luvannyuma lwa myezi esatu. Ku ddaala ly’okusiiga enzito, ssaako empapula ezifulumya wakati wa layers.

PTFE olugoye olw’ebbugumu eringi luwa ebirungi mukaaga ebikulu ng’omusipi ogutambuza okukuba ebitabo: kungulu okutali kukwata (okuziyiza okukuba ekikuta ne yinki okufuluma mu ngeri ennyonjo), okuziyiza ebbugumu 260°C (okukala okulungi), okunyweza ebipimo (<0.5% elongation, okuwandiisa okutuufu), obutakola eddagala (okuziyiza ebisiiga ebivunda), okusikagana okutono (okukola obulungi), n’okukyukakyuka (obugumu,, langi anti-okuziyiza okutambula). Kirungi nnyo mu kukuba ebitabo ku screen, okukuba ebitabo mu ngeri ya digito, n’okutambuza ebbugumu.

Anti-static PTFE high-temperature fabric egatta obutakwata, ebbugumu-okugumira (260°C), era chemically inert eby’obugagga ebya standard PTFE n’omulimu static-dissipative. Ebikulu ebikozesebwa: okukola ebyuma (PCB lamination, component handling), PV module lamination (okuziyiza ESD okwonooneka ku solar cells), okulongoosa emmere n’eddagala (ESD-safe baking liners), amakolero g’eddagala (anti-corrosion, anti-static ducting), n’amakolero g’engoye/okukuba ebitabo. Obuziyiza obw’okungulu mu ngeri entuufu buba 106–109 Ω.

PTFE obutambi obw’ebbugumu eringi obuterekeddwa mu ngeri y’omuzingo busobola okutawaanyizibwa okunywerera wakati wa layeri (okuzibikira) n’okukyusa okwesiiga ku ludda olutakwata. Ebikoola ebivaako: PTFE film elastic memory ne silicone PSA creep wansi wa puleesa n’ebbugumu. Ekigonjoola: okusika omuguwa mu bbanga (gradient winding tension) – kunywevu ku layers ez’ebweru, okusumululwa ku layers ez’omunda – nga okozesa okufuga okusika kwa closed-loop. Okujjuliza n’okusiiga okusumulula, okutereka obulungi (15-40°C, 30-70% RH), okuteeka mu bbanga, n’okukyusakyusa omuzingo buli luvannyuma lwa myezi esatu.

Obulamu bw’obuweereza bw’olugoye olw’ebbugumu eringi PTFE bwawukana nnyo okusinziira ku kukozesebwa. Chemical anti-corrosion lining esobola okumala emyaka 3+ (4x okusinga kapiira). Tray z’okufumba emmere emyezi egiyise nga tezivunda nnyo. Emisipi egy’amakolero egy’okutambuza ebintu gyambala olw’okusikagana. PV lamination (150°C, EVA contact) erina obulamu obw’ekigero. Ebikozesebwa mu kusikagana okuzito (abrasive discs) biba n’obulamu obutono. Ensonga enkulu: okufuga ebbugumu (sigala ≤260°C), weewale okunyiga ebisongovu, okuyonja buli kiseera, n’okukyusa mu budde ng’ofunye ebizimba oba ebya kyenvu.

PTFE ttaapu ey’ebbugumu eringi ekozesebwa mu kukwatagana n’emmere erina okussa ekitiibwa mu kkomo ly’ebbugumu erikakali: ≤260°C okukozesebwa obutasalako (tewali kkomo ku budde), 260-300°C okumala eddakiika eziwera 30 zokka, ne >300°C ekugirwa. Tape eno ya kukwatagana butereevu kwokka (tray liners, heat sealer covers), so si kuzinga mmere butereevu. Tokolangako nga tolina mmere (dry heating). Kikyuseemu singa oba olina ebizimba, ebya kyenvu oba ebyambala.

Olugoye lwa PTFE olw’ebbugumu eringi (PTFE-coated fiberglass) lusinga okuwangaala nga lukuumibwa wansi wa 260°C, nga luli wala n’ebiwujjo ebisongovu, era nga luyonjebwa n’ebikozesebwa ebigonvu. Ensonga enkulu ezikoma ku bulamu: okuvunda kw’ebbugumu okusukka 260°C, okusannyalala kw’ebbugumu okuva mu kubuguma/okunyogoga okw’amangu, obukoowu bw’ebyuma okuva mu kubeebalama n’okusika, okulumbibwa eddagala okuva mu byuma bya alkali ebisaanuuse oba ebiwunyiriza eby’amaanyi, okwonooneka okuva mu byuma ebisekula ebyuma nga byoza, n’okukwatibwa UV okukozesebwa ebweru. Omutindo gw’okusiiga ne substrate nagwo gukulu.

Olugoye lwa PTFE olw’ebbugumu eringi lunywevu okutuuka ku 300°C, naye mu muliro luvunda ne lufulumya ggaasi ez’obutwa ennyo: hydrogen fluoride (HF) (corrosive, pulmonary edema) ne perfluoroisobutylene (PFIB) (ezitaliiko langi, teziwunya, ~10x esinga obutwa okusinga phosgene, temuli antidote). Era ne kaboni monokisayidi, ebisigalira bya PFOA, ne trace dioxins. Masiki eza bulijjo ezifuuwa omukka tezikola; kozesa ekyuma ekissa ekyetongodde (SCBA). Obubonero buyinza okulwawo.

Silicone pressure-sensitive adhesives (PSA) ku PTFE obutambi obw’ebbugumu eringi zaawukana nnyo mu kukola kw’okukaddiwa okw’ebbugumu eringi. Methylphenyl silicone PSA ekuuma amaanyi g’ebikuta >85% oluvannyuma lwa 250°C/ennaku 7, ate ekika kya methyl ekya bulijjo kikka okutuuka ku 50-70%. Enkola eziwonyezebwa (addition-cured) (hydrosilylation) ziwa okutebenkera okulungi ennyo okusinga okuwonyezebwa perokisayidi. Okusobola okuweereza obutasalako ku 200°C+, londa ebika bya phenyl ebingi ebiwonye n’okugattako.

Obutambi obutambuza ebbugumu obwa PTFE pressure-sensitive adhesive (PSA) bulina okutambuza ebbugumu nga busigala nga bukwatagana. Okwongerako ebijjuza kiyamba okutambuza ebbugumu naye kiruma okunyweza. Bbalansi ennungi ekozesa obutundutundu obunene obw’enkulungo (nga conductive skeleton) obutabuddwamu obutundutundu obutono (okujjuza ebifo ebitaliimu), okukuuma omugatte gw’okutikka okujjuza waggulu ddala w’omusingi gw’okukulukuta. Weewale ebikuta n’ebiwuziwuzi; batta tack.
