▪Ethylene Propylene Diene Monomer (EPDM)
Labala ya EPDM ndiyokhazikika kuzinthu zambiri, motero imagwiritsidwa ntchito kwambiri m'makampani azakudya.Ubwino wina ndi wakuti ukhoza kugwiritsidwa ntchito pa kutentha kovomerezeka kwa 140 ° C (244 ° F), koma palinso malire.EPDM siimalimbana ndi mafuta achilengedwe, mafuta osakhazikika komanso mafuta, koma imakhala ndi kukana kwa ozoni.
▪Silicone Rubber (VMQ)
Khalidwe lodziwika bwino la rabara ya silikoni ndikuti imatha kupirira kutentha kuchokera -50 ° C (-58 ° F) mpaka pafupifupi +180 ° C (356 ° F) ndikusungabe kukhazikika kwake.Kukhazikika kwa mankhwala kumaloledwabe pazinthu zambiri, komabe, soda lye ndi asidi komanso madzi otentha ndi nthunzi zimatha kuwononga mphira wa silicone, kukana kwa ozoni wabwino.
▪Nitrile Rubber (NBR)
NBR ndi mtundu wa mphira womwe umagwiritsidwa ntchito nthawi zambiri pazinthu zaukadaulo.Ndiwokhazikika kwambiri ku ma hydrocarbon ambiri monga mafuta, mafuta ndi mafuta, komanso kusungunula alkalis ndi nitric acid, ndipo angagwiritsidwe ntchito pa kutentha kovomerezeka kwa 95 ° C (203 ° F).Popeza NBR imawonongedwa ndi ozoni, siingathe kuwonetseredwa ndi kuwala kwa UV ndipo iyenera kutetezedwa kuti isakhale ndi kuwala.
▪Fluorinated Rubber (FPM)
FPM imagwiritsidwa ntchito nthawi zambiri pomwe mitundu ina ya mphira si yoyenera, makamaka pa kutentha kwambiri mpaka 180 ° C (356 ° F), yokhala ndi kukhazikika kwa mankhwala.ndi kukana ozonimankhwala ambiri, koma ayenera kupewa madzi otentha, nthunzi, lye, asidi ndi mowa.
▪Polytetrafluoroethylene (PTFE)
PTFE ili ndi kukhazikika kwa mankhwala komanso kukana kwa dzimbiri (ndi imodzi mwazinthu zabwino kwambiri zosagwira dzimbiri padziko lapansi masiku ano, kupatula zitsulo zosungunula za alkali, PTFE sichidzimbiritsidwa ndi mankhwala aliwonse opangira mankhwala).Mwachitsanzo, akaphika mu sulfuric acid, nitric acid, hydrochloric acid, mowa, kapena ngakhale mu aqua regia, kulemera kwake ndi ntchito zake sizingasinthe.Kutentha kwa ntchito: -25°C mpaka 250°C
