Pono ʻo PTFE fiberglass tape i ʻekolu mau palapala hōʻoia palekana: UL (palekana uila a me ka lapalapa ahi), FDA (hoʻopili pili meaʻai), a me ISO 9001:2015 (hoʻokele maikaʻi). Hāʻawi nā lipine i hōʻoia ʻia i ka hana maʻamau, ke ola ʻoi aku ka lōʻihi o ka lawelawe ʻana, a me ka haʻahaʻa haʻahaʻa o ke kumu kūʻai ʻoiai ke kumu kūʻai kiʻekiʻe. E hōʻoia mau i nā palapala hōʻoia me nā hui hoʻopuka.

Hoʻohana ʻia ka lipine wela kiʻekiʻe o ka PTFE ma waena o ʻekolu mau lāʻau noiʻi lapaʻau: ka pale ʻana i nā mea hana sterilization (autoclave trays, heat-seal packaging), mea hoʻomaʻamaʻa ʻili (ka uhi haʻahaʻa haʻahaʻa, insulation uila), a me nā mea implantable (vascular grafts, sutures). Ua hōʻoia ʻia ka biocompatibility ma o ISO 10993, a ua hoʻokumu ʻo FDA 21 CFR 177.1550 i ka palekana kumu.

PTFE kiʻekiʻe-mehana lipine i ilihune kū'ē i ka ionizing radiation. Ma ka 1 kGy hoʻolaha gamma wale nō, hāʻule ka ikaika tensile i ~25% o ke kumu. He kūpono wale ia no nā wahi haʻahaʻa haʻahaʻa (meaʻai/lāʻau sterilization <10 kGy). No ka ʻoihana nuklea a i ʻole nā ​​mokulele mokulele, e hoʻohana i ka polyimide a i ʻole PEEK ma kahi.

No ka PTFE kiʻekiʻe-mehana lipine ma lalo o ka lōʻihi-manawa immersion, ka PTFE substrate noho chemically inert, akā, o ka adhesive papa ka wahi nāwaliwali. Hoʻonāwaliwali ka wai i ka PSA silicone; ʻO ka wai paʻakai ka hoʻokē ʻino. No nā kinikona koʻikoʻi, koi ʻia nā fluorosilicone a i ʻole perfluoropolyether adhesives – a i ʻole ka lipine PTFE adhesive-free. ʻO ka pau ʻana o ka ikaika Peel a hiki i 40% ma hope o 48 mau hola i ka wai.

Pono e noho i loko o nā palena wela o ka PTFE i hoʻohana ʻia i nā noi pili meaʻai: ≤260°C no ka hoʻohana mau ʻana, ≤300°C no nā piko pōkole (mau minuke), ʻaʻole ma luna o 327°C (decomposition). ʻAʻole ʻōlelo nā kānāwai FDA a me EU i ka palena manawa āpau - pili ka lōʻihi o ka launa pū ʻana i ka mahana a pono e hōʻoia ʻia e nā hoʻokolohua migration e hoʻohālikelike ana i nā kūlana maoli.

ʻO ke koho ʻana i ka lipine wela kiʻekiʻe PTFE kūpono no kahi moena wela 3D paʻi e pono ai ka nānā ʻana i ʻehā mau hōʻailona nui: ke kūpaʻa wela (a hiki i 260°C+), ka substrate i hoʻoikaika ʻia i ka fiberglass (0.18mm maikaʻi), ke kākoʻo silicone me ka ʻili o luna ʻole, a me ka laulā kūpono. Kōkua kēia alakaʻi iā ʻoe e pale aku i ka pale ʻana, ke koena, a me ka paʻi ʻana.

ʻO ke koho ʻana i ka pepa hoʻokuʻu a i ʻole ka substrate kiʻiʻoniʻoni a me ka mea hoʻokuʻu e pili pono i ka paʻa o ka mālama ʻana a me ka hana ʻili ʻana o ka tape wela kiʻekiʻe PTFE. Hoʻohālikelike kēia ʻatikala i ka PET vs. kraft paper substrates a me ka silicone vs. fluorinated release agents, e paipai ana i ka hoʻohui maikaʻi loa no ka ʻili ʻana i ka ʻili a me ka hilinaʻi lōʻihi.
