Makampani a Zitsulo ndi Chemical Processing Viwanda akhala akugwiritsa ntchito zinthu zamachubu a fluoropolymer kuchokera ku zinthu monga PTFE ndi mapaipi kwazaka zambiri posamutsa mankhwala owopsa kwambiri kapena owononga.Mochulukirachulukira, chubu cha PTFE chikulowa m'malo mwa mpweya ndi mapaipi ena achitsulo omwe amawonongeka mwachangu.Tsopano komanso m'tsogolomu, PTFE ipitilizabe kugulitsa malonda muzofunikira.
Chemical Quality*: PTFE ndi inert ku mankhwala zotsatirazi
| Ma Inorganic Chemicals | Mankhwala a Organic | Zina |
| Aqua Regia | Mowa | Zamadzimadzi Zachilengedwe |
| Hydrofluoric Acid | Esters | Mafuta onunkhira |
| Kutentha kwa Sulfuric Acid | Ketoni | Chakudya |
| Chlorosulfuric Acid | Ma Halogenated Organics | Kusindikiza Inks & Dyes |
| Kutentha kwa sodium hydroxide Solution | Zosungunulira Zonunkhira | Low Level Radioactive Zinthu |
| Mafuta a Chlorine | Amines | Oxidizers |
| Hydrogen Peroxide | Mafuta a Industrial | |
| Acid Chlorides | ||
| Kutentha, Kutentha kwa Nitric Acid |
*Mwa mankhwala okhawo omwe amadziwika kuti amaukira PTFE ndi zitsulo zosungunuka za alkali ndi njira zake, chlorine trifluoride, ndi gaseous fluorine pa kutentha kwakukulu ndi kupanikizika.
Mkhalidwe Wotentha:
Machubu a PTFE amatha kupirira kutentha mpaka 680 °F kwa nthawi yochepa.* Munthawi yovuta, PTFE imakhalabe yolimba mpaka -320 °F.
*Pamwamba pa 500 °F, zinthu zamakina zimakhala zolepheretsa
Mphamvu Zamagetsi:
Machubu a PTFE ali ndi mphamvu zapamwamba kwambiri zamagetsi, zomwe zimawonetsedwa ndi kutsika kwa dielectric kosasintha kwa 2.1 pakati -40 °F ndi 480 °F mkati mwamafupipafupi a 5 Hz mpaka 10 GHz.
PTFE chubu ndi insulator yabwino kwambiri yokhala ndi resistivity ya pamwamba ya 3.6 X 1012 ohms (ngakhale pa 100% chinyezi wachibale).
Mphamvu za dielectric za nthawi yochepa zimachokera ku 500 volts / mil (1 mil = 10-3 mkati) chifukwa cha makulidwe oposa 100 mils mpaka 4000 volts / mil kwa mafilimu oonda kwambiri.
Ubwino wa UV ndi Ma radiation*:
Machubu a PTFE ali ndi kukana kwa UV bwino komanso kusinthasintha kwa nyengo, okhala ndi mlingo wa radiation wa PTFE pa 2 - 7 X 104 rads.Kusowa kwa okosijeni kumawonjezera kukana kwa radiation ndi gawo la osachepera 10.* Kukana kwa ma elekitironi ndi ma radiation a gamma ndikocheperako.
Makhalidwe Ovala ndi Kukangana:
PTFE chubu ali ndi poterera ndi yosalala pamwamba, ndi malo amodzi coefficient of 0.08 ndi 500 psi katundu.
Makhalidwe a PTFE amapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito ngati mapepala onyamulira, pansi pa zovuta zotsika kwambiri.Zitsanzo ndi zokhala ndi mlatho, zothandizira mapaipi, ndi zoyikapo zopangira zolemetsa.
