Thepi ya PTFE ya mahiselo yale henhla leyi tirhisiwaka eka switirhisiwa swa ku khumbana ka swakudya yifanele ku tshama eka swipimelo swa mahiselo leswi hlamuseriweke: ≤260°C eka kutirhisiwa loku yaka emahlweni, ≤300°C eka tinhlohlorhi to koma (timinete), naswona ayi tshuki yiva ehenhla ka 327°C (ku bola). Milawu ya FDA na EU a yi boxi nkarhi wa misava hinkwayo – nkarhi wa ku hlangana loku hlayisekeke wu titshege hi mahiselo naswona wu fanele ku tiyisisiwa hi swikambelo swa ku rhurha leswi tekelelaka swiyimo swa xiviri.

Thepi ya mahiselo yale henhla ya PTFE yi lava vuhlayiselo lebyi faneleke ku hlayisa ku namarhela ka yona, ku olova, na matirhelo ya ku humesa. Swilaveko swa nkoka swikatsa vulawuri bya mahiselo (10-30°C), ndzhongho wale hansi ka 60%, ku papalata ku vonakala, ku hambanisiwa ka ti khemikhali, ku vekiwa hiku yima, xikan’we naku nghenisiwa ka moya. Landzelela vulawuri bya nhundzu ya FIFO naswona u kambela nkarhi na nkarhi.

Ku hlawuriwa ka phepha ro humesa kumbe substrate ya filimi na xitirhisiwa xo humesa swi khumba hi ku kongoma ku tshamiseka ka vuhlayiselo na matirhelo ya ku rhurhumela ka thepi ya mahiselo ya le henhla ya PTFE. Xihloko lexi xi pimanisa PET vs. kraft paper substrates na silicone vs. fluorinated release agents, leswi ringanyetaka nhlanganelo lowunene wa zero-residue peeling xikan’we naku tshembheka ka nkarhi woleha.

Tithepi ta PTFE ta mahiselo yale henhla ti tirhisiwa ngopfu eka ku pfalela gezi, kambe swiyimo swa frequency yale henhla na voltage yale henhla switisa makhombo yo hlawuleka: ku tshoveka ka gezi, ku humesiwa ka xiphemu, ku dyuhala ka mahiselo, ku lahlekeriwa hi signal ya frequency yale henhla, na ku twisisa mbango. Xihloko lexi xi hlamusela khombo rin’wana ni rin’wana ni ndlela yo ri papalata.
