PTFE maualuga-vevela lipine faʻaogaina i naifi faʻamaufaʻailoga vevela ma faʻamaufaʻailoga faʻamaufaʻailoga e tuʻuina atu ai faʻamaufaʻailoga autu e fa: puipuia le pipii palasitika liusuavai (aveesea taimi faʻaletonu), puipuia mate faʻamaufaʻailoga taugata, homogenizes vevela / mamafa mo faʻamaufaʻailoga faifaipea, ma faʻaitiitia feteʻenaʻiga ata. O lo'o fa'atonuina le mea fa'apipi'i fa'apipi'i-fiberglass (0.13-0.25 mm) fa'atasi ai ma le PSA silicone (≥260°C). Anti-static lipine uliuli mo laina televave.

O le vai ausa pa pupuni meatotino o le PTFE faapipii lipine e fuafuaina muamua e le faʻaleagaina o le ufiufi (micropores, microcracks, fiber wicking) nai lo le PTFE's intrinsic hydrophobicity. O ata tifaga PTFE mama e ofoina atu na'o le WVTR. E fa'apipi'i fa'alava ma fa'atumu fa'atumu (mica, fa'amea tioata) e fa'atupu ai se labyrinth, fa'aitiitia ai le felauaiga ausa. Mo fa'amaufa'ailoga maualuga-sūsū, fa'amaoti fa'alavalava fa'ato'a.

Fetolofi teteʻe o le PTFE maualuga-vevela mea faapipii lipine i lalo o taimi umi uta tumau (aemaise lava i le 200-260°C) e fuafuaina e ni mea se lua: silicone PSA crosslink density (crosslinking maualuga e taofia tafe) ma substrate ituaiga (fiberglass-faamalosia PTFE tetee malulu fetolofi; mama ata tifaga PTFE fetolofi). O mea fa'apipi'i e le'i feso'ota'i e vave ona pa'u i le vevela tele. O fa'amau fa'apipi'i mafiafia e fa'ateleina ai le fa'alavelave fetolofi.

Mo le PTFE maualuga-vevela lipine fa'aaogaina i fa'aoga fete'ena'i fa'ase'e abrasive, e le lava le fa'amautu ma le fa'afefe vevela. Fa'atonuga o filifiliga autu: Taber abrasion gau (<15 mg/1000 cycles), fa'atumu suiga PTFE coating (carbon/graphite/MoS₂), PV fa'atapula'a fa'amaumauga, malosi substrate (≥200 N/cm), ma mating surface roughness (Ra 0.2-0.4 μm). O le puipuiga lelei o le pito ma le fusi atoa e taua tele mo le umi o le ola.

O le substrate PTFE e masani lava ona fa'asalaina masima masima (suavai vai <0.01%). Ae ui i lea, o le fa'atinoga atoa o lipine e fa'alagolago i le ituaiga pipi'i: PSA silicone e fa'afeagai ma si'osi'omaga o le gataifale (500-1000h su'ega masima,> 80% taofi pa'u); ua le manuia le PSA acrylic. Togafitiga lelei o luga, fa'aoga e leai ni pulumu, ma le fa'amaufa'ailoga pito i le fa'amaufa'ailoga silikoni e taua tele mo le fa'atuatuaina umi i luga o fa'afanua ma va'a i fafo.

PTFE fiberglass lipine e manaʻomia ni faʻamaoniga autu e tolu o le saogalemu: UL (eletise ma le afi saogalemu), FDA (tausi faʻafesoʻotaʻi meaʻai), ma le ISO 9001: 2015 (pulea lelei). O lipine fa'amaonia e ofoina atu le fa'atinoga faifaipea, umi le soifua tautua, ma fa'aititia le tau atoa o le pule e ui lava i le maualuga o le tau i luma. Fa'amaonia sa'o i taimi uma tusipasi fa'atasi ma tino e tu'uina atu.

PTFE maualuga-vevela lipine o loʻo faʻaaogaina i le tolu vaega faʻafomaʻi talosaga: puipuiga o meafaigaluega faʻamaʻi (autoclave fata, faʻamaufaʻailoga vevela), meafaigāluega togafitiga luga (faʻapipiʻi maualalo-fesoʻotaʻiga, insulation eletise), ma masini faʻapipiʻi (fusi vascular, sutures). Biocompatibility e faʻamaonia e ala i le ISO 10993, ma le FDA 21 CFR 177.1550 faʻavae le saogalemu o meafaitino.

PTFE maualuga-vevela lipine o loʻo i ai le le lelei o le teteʻe atu i le faʻavelaina o le ionizing. I le na'o le 1 kGy gamma fa'aalia, pa'u le malosi tete'e i le ~25% o le ulua'i. E talafeagai mo na'o siosiomaga maualalo-dose (mea'ai/fa'ama'i sterilization <10 kGy). Mo alamanuia faaniukilia po'o va'a va'alele, fa'aaoga le polyimide po'o le PEEK nai lo.

Mo PTFE lipine vevela maualuga i lalo o le faatofu umi, o le PTFE substrate tumau chemically inert, ae o le apa pipii o le vaega vaivai. O le vai e faʻavaivaia PSA silicone; vai masima e faatelevave ai le pala. Mo vailaʻau faʻamalosi, faʻapipiʻi fluorosilicone poʻo perfluoropolyether - poʻo le lipine PTFE e leai se pipii - e manaʻomia. Ole malosi ole pa'u ile 40% ile mae'a ole 48 itula ile vai.

PTFE maualuga-vevela lipine faʻaaogaina i talosaga faʻafesoʻotaʻi meaʻai e tatau ona tumau i totonu o tapulaa faʻamalamalamaina o le vevela: ≤260 ° C mo le faʻaaogaina pea, ≤300 ° C mo tumutumu pupuu (minute), ma e le sili atu i le 327 ° C (decomposition). O tulafono a le FDA ma le EU e le o fa'ama'otiina se taimi fa'atapula'a - le umi o feso'ota'iga saogalemu e fa'alagolago i le vevela ma e tatau ona fa'amaonia e su'ega femalaga'iga fa'atusa tulaga moni.
