Lapi ra mahiselo yale henhla ya PTFE (PTFE-coated fiberglass) rina ku tiya ka kahle swinene ka thermal shock endzeni ka ndzhawu ya rona ya ntolovelo yo tirha ya -70°C kuya eka 260°C. Yikota ku tiyisela ku rhendzeleka ka mahiselo hiku hatlisa, xikombiso, ku suka eka -50°C freezer kuya eka 260°C hot press. Ti grade ta premium ti pona hambi kuri ku kufumela ka xitshuketa kusuka eka 260°C kuya eka mati ya 10°C. Hambiswiritano, ku chavisa swilo leswi kusuka eka mahiselo yale henhla ka 300°C (ekusuhi na PTFE’s 327°C melting point) swita endla leswaku kuva na ku pandzeka ka xihatla xikan’we na delamination. Substrate ya fiberglass yinyika ku tiya ka dimensional; xifunengeto xa PTFE hi xona xi sivelaka.

Lapi ra mahiselo yale henhla ra PTFE ritirhisiwa ngopfu eka indasitiri ya tikhemikhali eka switirhisiwa swa nkoka swa nkombo: ti flange gaskets nati pipe linings (yi lwisana na ti acids/alkalis to tiya), ti reactor na ti tank linings (yi sivela ku bola ka nsimbi, ku basisiwa hiku olova), ti filter bags ta corrosive flue gas (kufika eka 260°C), ti anti-corrosion expansion joints ta ti ducts, anti-adhesion ti pads to welda, lapi ro humesa ra composite molding, na swifunengeto swo pfalela gezi/ku hisa. Tigredi ta FDA na UL ta kumeka.

PTFE lapi ra mahiselo yale henhla (PTFE-coated fiberglass) rinyika swipfuno swa mune swa nkoka tani hi anti-corrosion lining: ku nga tirhi ka tikhemikhali (ku lwisana na aqua regia, ti alkalis to tiya, swintshuxekisi), mahiselo yo anama (-70°C kuya eka 260°C kuya emahlweni, 350°C peak), kutshamiseka ka dimensional (<0.5% elongation), na vuandlalo lebyi nga namarheli (ku olova ku basisa, swi sivela ku hlengeletana). Yi tirhisiwa eka tiphayiphi ta tikhemikhali, swihondzo swo susa sulphur, mathangi yo pickling, na switirhisiwa swa swakudya/pharma. Tigredi ta FDA ta kumeka.

PTFE lapi ra mahiselo yale henhla rinyika swipfuno swa tsevu swa nkoka tani hi bandi ro fambisa ro gandlisa: vuandlalo lebyi nga namarheli (ku kandziyisa paste na inki ku humesiwa hiku basa), 260°C ku lwisana na kuhisa (ku omisa kahle), ku tiya ka dimensional (<0.5% elongation, ku tsarisiwa loku kongomeke), ku nga tirhi ka tikhemikhali (ku lwisana na ti paste leti bolaka), ku hlangana ka le hansi (ku tirha hi ndlela yo olova), na ku cinciwa (ku tiya,, ku cinciwa ka mihlovo anti-static). Yi kahle swinene eka ku kandziyisa hi xikirini, ku kandziyisa hi xidijitali, na switirhisiwa swo hundzisela ku hisa.

Anti-static PTFE high-temperature fabric yihlanganisa swihlawulekisi leswinga namarheli, leswinga tiyiselaka kuhisa (260°C), na leswinga tirhiki hi ti khemikhali swa standard PTFE na matirhelo ya static-dissipative. Switirhisiwa swa nkoka: vumaki bya swa elektroniki (PCB lamination, ku khoma swiphemu), PV module lamination (yi sivela ku onhaka ka ESD eka tisele ta dyambu), ku lulamisiwa ka swakudya na mirhi (ESD-safe baking liners), tipulani ta tikhemikhali (anti-corrosion, anti-static ducting), na tiindasitiri ta swiambalo/ku kandziyisa. Ku tiya ka le henhla hi ntolovelo 106–109 Ω.

Vutomi bya vukorhokeri bya lapi ra mahiselo yale henhla ya PTFE byi hambana swinene kuya hi xitirhisiwa. Tikhemikhali ta anti-corrosion lining tinga tshama 3+ wa malembe (4x yo leha kutlula rhaba). Titreyi to baka swakudya ti heta tinhweti tinga onhaki ngopfu. Mabandhi yo fambisa ya tiindasitiri ya onhaka hikwalaho ka ku hlangana. PV lamination (150°C, EVA contact) yina vutomi byo ringanela. Switirhisiwa swa friction yo tika (abrasive discs) swina vutomi byo koma. Swilo swa nkoka: ku lawula mahiselo (tshama ≤260°C), papalata ku rhurhumela loku tlhavaka, ku basisiwa nkarhi na nkarhi, na ku cinciwa hi nkarhi loko ku ri na swirhumbana kumbe ku tshwuka.

Lapi ra mahiselo yale henhla ra PTFE ritshamisekile kuya fika eka 300°C, kambe eka ndzilo ri bola naswona ri humesa tigasi letingana chefu swinene: hydrogen fluoride (HF) (corrosive, pulmonary edema) na perfluoroisobutylene (PFIB) (leyi nga riki na muhlovo, yingari na nun’hwelo, ~10x leyingana chefu kutlula phosgene, kungari na antidote). Nakambe khaboni monokisayidi, masalela ya PFOA, na ti trace dioxins. Swisirhelelo leswi tolovelekeke swa musi a swi tirhi; tirhisa switirhisiwa swo hefemula leswi tiyimeleke (SCBA). Swikombiso swi nga ha hlwela.

PTFE high-temperature fabric (PTFE-coated fiberglass) yikahle swinene eka microwave heating hikuva yi hundzisela ti microwaves handle ko tswonga eneji, yi lwisana na 260°C, naswona yina xivumbeko lexi nga namarheliki. Switirhisiwa swikatsa ti microwave baking mats, ti industrial dryer conveyor belts, ti reactor linings ta ku gayela ti khemikhali, na ti microwave popcorn bag liners. Tigredi ta FDA leti kumekaka eka ku hlangana na swakudya.

Lapi ra mahiselo yale henhla ya PTFE (PTFE-coated fiberglass) rina ku tiya ka flex lokunga kahle hikuva substrate ya fiberglass hi ntumbuluko yi brittle. Malapi yo olova (0.08mm) ya hanya eka madzana kuya eka magidi ya ku peta; ti grade to tika (>0.25mm) ti pandzeka endzhaku ka makume. Satin weave yi tlula plain weave. Eka ku gombonyoka loku yaka emahlweni ka reciprocating, languta filimi ya PTFE leyi tiyeke kumbe lapi leri sekeriweke eka aramid ematshan’wini ya sweswo.

Lapi ra mahiselo yale henhla ya PTFE (PTFE-coated fiberglass) ritirhisiwa ngopfu eka ku kandziyisa swiambalo na ku daya eka mabandhi yo gandlisa yo hundzisela ku hisa (180-230°C), swifunengeto swa tafula ro gandlisa hi xikirini, mabandhi ya mesh yo omisa, mabandhi ya muchini wo fusa, na ku phutsela hi roller. Vuandlalo bya yona lebyi nga namarheli byi sivela masalela ya inki/adhesive, leswi hungutaka nkarhi wo basisa na ku antswisa khwalithi ya malapi. Mabandhi lama nga heriki lama nga riki na swirhabyani ma endla leswaku ku va ni vuhumelerisi lebyi yaka emahlweni.
