PTFEyakatanga kugadzirwa kuti ishandiswe mumashandisirwo emuchadenga asi nenguva isipi yakawana imba mumaindasitiri asingaverengeki.PTFE yakasarudzika maitiro anosanganisira: makemikari inertness (mashoma makemikari anogona kuirwisa), yakanyanya kuderera coefficient ye friction (hapana chinogona kunamatira kune chinhu chine simba ripi zvaro), yakanyanya kupisa kupisa (inokwanisa kudziya tembiricha ye500 ° F) uye inobatsira zvakanyanya kutonhora kwekushisa nharaunda.
Ultem® / PEI (polyetherimide) ndeyepamusoro-simba amorphous polymer ine yakanakisa kupisa uye murazvo wemoto (inotakura chiyero chekupisa che94-V-0) ine hutsi hushoma hunobuda.Inoramba ichiita ku340 ° F, ichiita kuti ive yepamusoro kune zvigadzirwa zvepurasitiki seNylon neDelrin®.Ultem® mhinduro yakanaka kune zvikumbiro zvinoda simba rakawanda uye kugona kumira tembiricha yakakwira.Chigadzirwa chacho chinokodzerawo maapplication anoda anowirirana dielectric zvivakwa pamusoro peakawanda mafrequency.Ultem® inodzivirira hydrolysis uye inoshingirira zvakanyanya kune acidic mhinduro uye inokwanisa kushivirira inodzokororwa autoclaving kutenderera, senge inodzokororwa mupfu sterilization yezvishandiso zvekurapa zvinoshandiswa.Ultem® inoshandiswa zvakanyanya mumagetsi nekuda kweiyo yakanaka arc kuramba uye dielectric kugara.Zvimwe zvinojairwa maapplications zvinosanganisira analytical instrumentation uye zvimiro zvemukati zvinoda simba repamusoro uye kuomarara pane tembiricha dzakakwirira.
