Ka kakaretso, li-fluoropolymers li ntse li nkela lipolasetiki tse ling lits'ebetsong tsa bongaka butle-butle ka lebaka la bokhoni ba tsona ba ho fihlela litlhoko tsa 'mele le tsa biocompatibility tsa lithethefatsi le lisebelisoa tsa moloko o tlang.Li-fluoropolymers li kopana le litekanyetso tse ikhethang tsa ts'ebetso lits'ebetsong tse joalo.Tsena li kenyelletsa biocompatibility, lubricity, sterilization, inertness ea lik'hemik'hale, mocheso o pharaletseng oa tšebeliso ea mocheso, thepa e tlaase e tlamang lisebelisoa, bohloeki bo phahameng bo nang le lisebelisoa tse fokolang, thepa ea dielectric, le USP Class VI certification.
Lelapa la li-fluoropolymers tse fumanehang tse fihlelang litlhoko tse kaholimo li kenyelletsa limaraka tsa PTFE, FEP, PFA le PVDF ho tsoa ho bahlahisi ba fapaneng ba resin.PTFE(polymer) e na le nalane e kentsoeng hantle ea ho kenya lisele tse bonolo ka lebaka la ho lumellana ha eona le ho se sebetse ha eona.Baetsi ba lihlahisoa tsa resin le tse tlase ba ntse ba arabela litlhoko tse ncha tsa ts'ebetso ka ho etsa liphetoho tse nepahetseng k'hemistri ea resin le sebopeho sa bokaholimo ba lihlahisoa, ka ho latellana.
Biocompatibility ea polymer efe kapa efe ke tlhokahalo ea mantlha sesebelisoa sefe kapa sefe sa bongaka se joalo ka li-catheter, likepe tse nang le bio, lisyringe le li-sutures.PTFE, FEP le PVDF ke lisebelisoa tse lumellanang hantle le biocompatible, 'me mafura a tsona le lik'hemik'hale tse hanyetsanang le lik'hemik'hale li li etsa thepa ea khetho bakeng sa lihlahisoa tse kang li-tubing tse ngata tsa lumen le tse ling tse sebelisoang mekhoeng e fokolang haholo.Multi lumen fluoropolymer catheter tubing ka mohlala e lumella lingaka tse buoang ho etsa mekhoa e mengata li sebelisa catheter e le 'ngoe.
Fluoropolymers, haholo-holo PTFE(polymer) le PVDF li sebelisoa haholo ka har'a lera la microporous.Membranes, e nang le libilione tsa masoba ho tloha ka boholo ho tloha ho 0.01 ho isa ho 10 microns, li sebetsa e le lisefe tsa likaroloana le libaktheria ka har'a maro a bohlokoa.PTFE le PVDF ke tse ling tsa li-polymer tse 'maloa tse sebelisetsoang lera la sefe.Libaka tsa li-membrane tsa li-polymers li ka fetoloa ho fana ka thepa e khethehileng ea ho hloekisa 'me e ka ba hydrophobic (ho thibela metsi) le oleophobic (oli, solvent, low surface tension fluid repelling).Li-membrane tsa PVDF li ka boela tsa fetoloa holim'a metsi hore e be hydrophilic (ho rata metsi) bakeng sa ho tlosa likaroloana tsa kokoana-hloko ha ho etsoa liprotheine tsa phekolo le li-antibodies tsa monoclonal.Li-membrane tse koalang tsa PVDF li loketse ka ho khetheha bakeng sa immunoblotting e tlase (tlhahlobo ea blot ea bophirima), hammoho le tlhahlobo ea asiti ea amino le tatellano ea liprotheine.
