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 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 ka 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, ka adhesive papa ka mea 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.

Pono ka lipine kiʻekiʻe o ka PTFE i ka mālama pono e mālama i kona adhesion, maʻalahi, a me ka hoʻokuʻu ʻana i ka hana. ʻO nā koi koʻikoʻi e pili ana i ka mālama ʻana i ka mahana (10-30 ° C), ka haʻahaʻa ma lalo o 60%, ka pale ʻana i ka māmā, ka hoʻokaʻawale ʻana i nā kemika, ka waiho ʻana i ke kūpaʻa, a me ka ea. E hahai i ka hoʻokele waiwai FIFO a nānā mau.

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.

Hoʻohana nui ʻia nā lipine kiʻekiʻe o ka PTFE no ka insulation uila, akā ʻo nā kūlana kiʻekiʻe a me nā kūlana kiʻekiʻe-voltage e loaʻa i nā pilikia kūʻokoʻa: ka haki ʻana o ka uila, ka hoʻokuʻu hapa, ka ʻelemakule wela, ka nalowale o ka hōʻailona kiʻekiʻe, a me ka ʻike o ke kaiapuni. Hōʻike kēia ʻatikala i kēlā me kēia pilikia a pehea e pale aku ai iā lākou.
