Thepi ya mahiselo yale henhla ya PTFE yitirhisiwa eka ti tiers tinharhu ta matirhiselo ya swa vutshunguri: nsirhelelo wa switirhisiwa swo sterilization (ti autoclave trays, heat-seal packaging), vutshunguri bya le henhla ka switirhisiwa (low-friction coating, electrical insulation), na switirhisiwa leswinga nghenisiwa (vascular grafts, sutures). Biocompatibility yi tiyisisiwa hiku tirhisa ISO 10993, naswona FDA 21 CFR 177.1550 yi simeka vuhlayiseki bya masungulo bya switirhisiwa.

Thepi ya mahiselo yale henhla ya PTFE yina ku tiya lokunga kahle eka miseve ya ionizing. Eka 1 kGy ntsena ya gamma exposure, matimba ya tensile ya hunguteka kuya eka ~25% ya original. Yi lulamerile ntsena eka tindzhawu ta mpimo wale hansi (swakudya/ku sterilization ka swa vutshunguri <10 kGy). Eka bindzu ra nyutliya kumbe swihaha-mpfhuka swa le xibakabakeni, tirhisa polyimide kumbe PEEK ematshan’weni ya sweswo.

Thepi ya mahiselo yale henhla ya PTFE yi lava vuhlayiselo lebyi faneleke ku hlayisa ku namarhela ka yona, ku olova, na matirhelo ya ku humesa. Swilaveko swa nkoka swikatsa vulawuri bya mahiselo (10-30°C), kutsakama ehansi ka 60%, ku papalata ku vonakala, ku hambanisiwa ka ti khemikhali, ku vekiwa ka vertical, na ku nghenisiwa ka moya. Landzelela vulawuri bya nhundzu ya FIFO naswona u kambela nkarhi na nkarhi.

Xihloko lexi xi hlamusela ndlela yo sivela ku thyakisa na ku onhaka ka matirhelo eka tlhelo leri nga namarheliki ra thepi ya mahiselo ya le henhla ya PTFE hi nkarhi wa endlelo ro peta. Maendlelo ya nkoka ya katsa vulawuri bya xihlovo (ku tshungula ka le henhla loku kongomeke), ku hambanisiwa hi nyama (tifilimi to sirhelela, ti non-stick rollers, zoned drying), na
