PTFE inonzi thermoplastic polymer, iri chena yakasimba patembiricha yemumba, ine density inoita 2200 kg/m3.Inochengetedza simba repamusoro, kuomarara uye kuzvigadzika patembiricha yakaderera kusvika pa5 K (−268.15 °C; -450.67 °F), uye kuchinjika zvakanaka patembiricha iri pamusoro pe194 K (-79 °C; -110 °F).PTFE inowana zvivakwa zvayo kubva paaggregate mhedzisiro yecarbon-fluorine bond, sezvinoita ese mafluorocarbons.Iwo ega makemikoro anozivikanwa kukanganisa aya kabhoni-fluorine zvisungo simbi dzinoshanda zvakanyanya senge alkali simbi, uye pakupisa kwepamusoro zvakare simbi sealuminium nemagnesium, uye fluorinating agents senge xenon difluoride uye cobalt (III) fluoride.
Iyo coefficient ye friction yemapurasitiki inowanzoyerwa nesimbi yakakwenenzverwa.PTFE's coefficient of friction i 0.05 kusvika 0.10, inova yechitatu-yakaderera pane chero chinhu chakasimba chinozivikanwa.PTFE's resistance to van der Waals forces zvinoreva kuti ndiyo chete nzvimbo inozivikanwa pasinganamatire chipembere.Ichokwadi, PTFE inogona kushandiswa kudzivirira tumbuyu kukwira kumusoro kwakapendwa nezvinhu.PTFE inotsvedza zvekuti zvipembenene hazvigone kubata uye zvinowanzodonha.
Nekuda kwekemikari inertness, PTFE haigone kuchinjika senge elastomer.Naizvozvo, haina "yeuko" uye inogona kukambaira.Nekuda kwehukuru hwayo hwemakemikari uye hwekupisa, PTFE inowanzoshandiswa sechinhu chegasket mukati meindasitiri inoda kuramba kumakemikari ane hukasha akadai semishonga kana kugadzirwa kwemakemikari.Nekudaro, nekuda kwekuda kunyura, kuita kwenguva refu kwezvisimbiso zvakadaro kwakaipa kupfuura kwema elastomers anoratidza zero, kana pedyo-zero, mazinga ezvinokambaira.
Kugadzira PTFE kunogona kuve kwakaoma uye kudhura, nekuti tembiricha yekunyungudika, 327 °C (621 °F), iri pamusoro petembiricha yekuora kwekutanga, 200 °C (392 °F).Kunyangwe kana yakanyungudutswa, PTFE haiyerere, asi pachinzvimbo ichizvibata senge gel nekuda kwekushaikwa kwekristaro chikamu uye yakakwira melt viscosity.
Zvimwe zvikamu zvePTFE zvinogadzirwa nekutonhora-kuumba, chimiro chekumanikidza kuumba.Pano, PTFE yakapfava yehupfu inomanikidzwa kuita mold pasi pekumanikidzwa kwakanyanya.Mushure menguva yekugadzika, inogara kubva pamaminetsi kusvika kumazuva, mold inodziya pa 360 kusvika 380 madhigirii celsius, ichibvumira zvimedu zvakanaka kuti zvibatane muhuremu humwe.
