Vespel ndi chizindikiro cha mitundu yosiyanasiyana ya mapulasitiki olimba a polyimide opangidwa ndi DuPont.Polytetrafluoroethylene (PTFE) ndi fluoropolymer yopanga ya tetrafluoroethylene yomwe ili ndi ntchito zambiri.Dzina lodziwika bwino la PTFE-based formulas ndi polymer by Chemours.Chemours ndi gawo la DuPont Co., lomwe linapeza malowa mu 1938.
Kuyerekeza kwa Polymer PTFE/FEP ndi Vespel Property Values
Ntchito Zofunika
Polima PTFE/FEP:Cabling mayankho; Non mafuta fani; O-mphete; Zisindikizo; Capacitors; Semiconductor kupanga; High kutentha mbali magetsi; Gaskets; Vavu zigawo.
Vespel:Polima wochita bwino kwambiri uyu amagwiritsidwa ntchito kwambiri muzamlengalenga, semiconductor ndiukadaulo wamayendedwe.Zimaphatikiza kukana kutentha, kutsekemera, kukhazikika kwa mawonekedwe, kukana kwa mankhwala, ndi kukana kwamphamvu, kuti zigwiritsidwe ntchito m'malo ovuta komanso owopsa a chilengedwe. Mosiyana ndi mapulasitiki ambiri, samatulutsa kutuluka kwakukulu ngakhale pa kutentha kwakukulu, zomwe zimapangitsa kuti zikhale zothandiza kwa zishango zotentha zopepuka. ndi chithandizo chamankhwala.Zimagwiranso ntchito mu vacuum applications, mpaka kutentha kwambiri kwa cryogenic.Komabe, Vespel imakonda kuyamwa madzi pang'ono, zomwe zimapangitsa kuti pakhale nthawi yayitali yopopera pomwe imayikidwa mu vacuum.
Zinthu Zakuthupi
PolimaPTFE/FEP:Zinthu zabwino kwambiri za dielectric; Kusakhazikika kwamankhwala ambiri; Kutentha kwakukulu ndi kukana kwamankhwala; Coeffiecient yotsika kwambiri ya mikangano; Kukaniza bwino kwa ma radiation; mayamwidwe a zero; Kusamva mphamvu pafupipafupi; Kuchita bwino.
Vespel:Kugwira ntchito mosalekeza mpaka 600 ° F; Palibe zida zapadera zamakina zomwe zimafunikira; Zokhazikika pang'ono; Zimagwira ntchito pama PV okwera kwambiri; Siziwonongeka ngakhale kutentha kwapansi paziro;Kutheka.
