PTFE lapi ra mahiselo yale henhla na lapi ra silicone hivumbirhi bya swona switirhisa lapi ra fiberglass tani hi xisekelo kambe swihambana hi switirhisiwa swo peta (PTFE resin vs silicone rubber). PTFE yi humelela swinene eka ku nga namarheli, ku lwisana na ku onhaka, na ku lwisana na tikhemikhali ku fika eka 260°C. Lapi ra silicone rinyika ku olova lokukulu, ku pfaleriwa ka gezi, na ku tiya ka ndzilo (kufika eka 230°C). Hlawula hi ku ya hi leswi u swi rhangisaka emahlweni.

PTFE lapi ra mahiselo yale henhla (PTFE membrane material) i xihlawuhlawu xa premium eka tensile architecture. Swipfuno swa nkoka: vutomi byale handle bya malembe ya 30+, ndzhawu yo ti basisa (mati ya mpfula ya hlantswa thyaka), ku hundziseriwa ka ku vonakala ko olova (6-13%), Class A fire rating, na matimba yofana na nsimbi ehansi ka 1.5 kg/m2. Yi tirhisiwa eswitediyamu, eswihambukelweni swa swihaha-mpfhuka ni le miakweni leyi nga ni swifaniso emisaveni hinkwayo.

Ku cheriwa ka PTFE aswi pimiwi eka lapi ra fiberglass ntsena. Atikili leyi yi tivisa 7 wa ti substrates tin’wana – aramid, carbon fibre, PBI, porous metal, graphite, asbestos (phased out), na ti ceramic fillers – na swihlawulekisi swa tona swa maendlelo, swipfuno, swipimelo, na matirhiselo ya nkoka.

Xihloko lexi xi hlamusela leswaku hikokwalaho ka yini lapi ra fiberglass leri nga riki na alkali ri ri substrate leyi tsakeriwaka eka lapi ra PTFE ra mahiselo yale henhla. Yi katsa ku hlanganisiwa ka tikhemikhali hiku tirhisa ti silane coupling agents xikan’we na swivumbeko swa nkoka swa physical swofana na thermal stability, dimensional stability, na corrosion resistance – ku tiyisisa matirhelo yo leha eka tindzhawu to tika.
