Kalendering - kaomi ʻana i ka lole i uhi ʻia i ka PTFE ma waena o nā wili aniani wela ma 360-380 ° C - hoʻololi nui i ka morphology ili, hoʻokuʻu i nā waiwai, impermeability, a me ka hana mechanical. Hoʻemi ia i ka roughness mai Ra 0.5-1.0 μm a i <0.05 μm, hoʻopaʻa i nā pinholes, hoʻomaikaʻi i ka pale ʻana, akā hoʻemi i ka ikaika o ka waimaka a me ka maʻalahi. Pono no ka hoʻokuʻu ʻana i nā liner a me ka hoʻokaʻawale uila.

ʻO ka lole wela kiʻekiʻe ʻo PTFE (PTFE membrane material) he koho maikaʻi loa no ka hoʻolālā tensile. ʻO nā pōmaikaʻi nui: 30+ makahiki ke ola i waho, hoʻomaʻemaʻe iā ia iho (holoi ka lepo i ka wai ua), hoʻouna māmā māmā (6-13%), helu ahi papa A, a me ka ikaika like me ke kila ma lalo o 1.5 kg/m². Hoʻohana ʻia i nā kahua pāʻani, nā mokulele, a me nā hale kiʻiʻoniʻoni a puni ka honua.

ʻAʻole i kaupalena ʻia ka impregnation PTFE i ka lole fiberglass. Hōʻike kēia ʻatikala i nā substrate ʻē aʻe 7 - aramid, carbon fiber, PBI, porous metal, graphite, asbestos (phased out), a me nā mea hoʻopiha ceramic - me kā lākou mau hiʻohiʻona kaʻina, nā pono, nā palena, a me nā noi nui.
