Ultem® / PEI (polyetherimide)ndi polymer yamphamvu kwambiri ya amorphous yokhala ndi kutentha kwambiri komanso kukana moto (yokhala ndi mphamvu yoyaka 94-V-0) yokhala ndi utsi wochepa.Imagwira mosalekeza mpaka 340 ° F, ndikupangitsa kuti ikhale yapamwamba kuposa mapulasitiki azinthu monga Nylon ndi Delrin®.
PTFEidapangidwa poyambilira kuti igwiritsidwe ntchito muzamlengalenga koma posakhalitsa idapeza nyumba m'mafakitale osawerengeka.Makhalidwe apadera a PTFE ndi awa: kusakhazikika kwamankhwala (mankhwala ochepa kwambiri amatha kuwukira), kukangana kochepa kwambiri (palibe chomwe chingamamatire ku zinthuzo ndi mphamvu iliyonse), kukana kutentha kwambiri (kutha kutentha kwa 500 ° F) komanso zothandiza kwambiri malo ozizira kutentha.
Ultem® / PEI (polyetherimide) ndi polyetherimide yamphamvu kwambiri yokhala ndi kutentha kwambiri komanso kukana moto (yokhala ndi mphamvu yakuyaka ya 94-V-0) yokhala ndi utsi wochepa.Imagwira mosalekeza mpaka 340 ° F, ndikupangitsa kuti ikhale yapamwamba kuposa mapulasitiki azinthu monga Nylon ndi Delrin®.Ultem® ndi njira yabwino yothetsera mapulogalamu omwe amafunikira mphamvu zambiri komanso kupirira kutentha kwambiri.Chogulitsacho chimagwirizananso ndi ntchito zomwe zimafuna ma dielectric osasinthika pama frequency osiyanasiyana.Ultem® ndi hydrolysis kugonjetsedwa ndi kwambiri kugonjetsedwa ndi acidic mayankho ndipo amatha kulolera mobwerezabwereza autoclaving mkombero, monga mobwerezabwereza nthunzi yotseketsa pa zipangizo zachipatala reusable.Ultem® imagwiritsidwa ntchito kwambiri pamagetsi chifukwa cha kukana bwino kwa arc komanso kusasintha kwa dielectric.Ntchito zina zodziwika bwino zimaphatikizapo zida zowunikira ndi zida zamapangidwe zomwe zimafunikira mphamvu zambiri komanso kusasunthika pakutentha kokwera.
Kuyerekeza kwa Polima PTFE/FEP ndi Ultem® / PEI (polyetherimide) Makhalidwe a Katundu
Ntchito Zofunika
polima PTFE/FEP: Mayankho a cabling; mayendedwe osapaka mafuta; mphete za O; Zisindikizo; Ma capacitors; Kupanga kwa semiconductor; Kutentha kwakukulu kwamagetsi; Magesi; Zigawo za valve.
Ultem® / PEI (polyetherimide) 
efense & okonda zakuthambo; Zolumikizira; Zisindikizo;Pampu & mavavu.
Zinthu Zakuthupi
polima PTFE/FEP: Zinthu zabwino kwambiri za dielectric;Kusakhazikika kwamankhwala ambiri;Kutentha kwakukulu ndi kukana kwamankhwala;Kutsika kwambiri kophatikizana kwa mikangano;Kukaniza bwino kwa ma radiation;Kuyamwa kwachinyontho zero;Kupanda chidwi ndi ma frequency amphamvu;Kutheka.
Ultem® / PEI (polyetherimide): Yamphamvu kwambiri komanso yolimba; FDA imagwirizana ndi magiredi omwe alipo; Kukana kwamankhwala kwakukulu; Mphamvu yayikulu ya dielectric.
