Warshadaha Biraha iyo Warshada farsamaynta Kiimikada waxay isticmaalayeen alaabada tubbada fluoropolymer ee agabka sida PTFE iyo tuubooyinka sanado badan si ay u gudbiyaan kiimikooyin aadka u wasakhaysan ama daxalka leh.In ka badan iyo in ka badan, tuubada PTFE ayaa beddelaysa kaarboon iyo tuubooyin kale oo bir ah kuwaas oo si degdeg ah u xumaanaya.Hadda iyo mustaqbalka, PTFE waxay sii wadi doontaa inay u adeegto warshadaha codsiyada muhiimka ah.
Sifooyinka Kiimikada*: PTFE waa mid aan la taaban karin kiimikooyinka soo socda
| Kiimikada aan Organic | Kiimikada dabiiciga ah | Mid kale |
| Aqua Regia | Khamriga | Dheecaannada noolaha |
| Hydrofluoric acid | Esters | Udgoon |
| Sulfuric acid qiiqaya | Ketones | Cunto |
| Chlorosulfuric acid | Organics Halogenated Heer Sare ah | Daabacaadda Khadadka & Midabka |
| Karkari Sodium Hydroxide Solution | Xalka udgoon | Walxaha Shucaaca ah ee Heerka Hoose |
| Gaaska Chlorine | Aamiin | Oxidiyeyaasha |
| Hydrogen peroxide | Saliida Warshadaha | |
| Acid Chlorides | ||
| Kulul, Acid Nitric Acid |
Kiimikooyinka kaliya ee loo yaqaan inay weeraraan PTFE waxaa ka mid ah biraha alkali ee dhalaalay iyo xalkooda, chlorine trifluoride, iyo fluorine gaseous ah oo heerkul sare ah iyo cadaadisyo.
Heerarka kulaylka:
Tuubooyinka PTFE waxay u adkeysan karaan heerkulka ilaa 680 °F waqtiyo xaddidan.
* In ka badan 500 °F, guryaha makaanikada ayaa noqda qodob xaddidaya
Tayada Korontada:
Tuubooyinka PTFE waxay leeyihiin sifooyin koronto oo heer sare ah, oo lagu muujiyey koronto yar oo joogto ah oo ah 2.1 inta u dhaxaysa -40 °F iyo 480 °F inta u dhaxaysa inta jeer ee 5 Hz ilaa 10 GHz.
Tuubooyinka PTFE sidoo kale waa dahaye heersare ah oo leh iska caabin dusha sare ah oo ah 3.6 X 1012 ohms (xitaa 100% qoyaan qaraabo ah).
Awoodaha dielectric ee wakhtiga gaaban waxay u dhexeeyaan 500 volts/mil (1 mil = 10-3 in) dhumucda ka weyn 100 mils ilaa 4000 volts/mil filimaanta aadka u khafiifka ah.
UV iyo tayada Shucaaca*:
Tuubooyinka PTFE waxay leeyihiin iska caabin UV aad u wanaagsan iyo cimilada, oo leh xadka qiyaasta shucaaca ee PTFE at 2 – 7 X 104 rads.Maqnaanshaha ogsijiinta waxay kordhisaa caabbinta shucaaca ugu yaraan 10.
Sifooyinka Xiro iyo Xubinta:
Tuubooyinka PTFE waxay leeyihiin dusha sibiqsan oo siman, oo leh isugeyn taagan oo is jiid jiid ah 0.08 iyo 500 psi.
Guryaha PTFE waxay si gaar ah ugu habboon yihiin in loo isticmaalo sida suufka xajka, iyadoo lagu hoos jiro cadaadis sare oo xawaare hooseeya.Tusaalooyinka waxaa ka mid ah suufka buundada, suufyada taageerada tuubada, iyo suufka dhejinta ee wax soo saarka culus.
