Rubber ea silicone e na le matla a phahameng a ho tsuba a phahameng le a tlaase, e boloka elasticity e ngata ho -70 ° C ho ea ho +260 ° C, e hanelloa ke ozone le meteoing, 'me e tšoanela ho tiisa gasket ka likhalase tsa thermomechanical. E seng chefo, e ka etsa hore ho be le likhallelo, lihlahisoa tsa ho qhekella le lihlahisoa tsa rabara tsa bongaka. Ka nako e ts'oanang, e na le litšoantšiso tse ntle haholo tse kang metsi a sa keneleng metsi, mahlaseli a mollo, mahlaseli a phahameng a motlakase, tsamaiso ea motlakase, ho itšireletsa le ho hanyetsa oli. E sebelisoa haholo liindastering tse sa tšoaneng tse kang mechine, lisebelisoa tsa elektronike le li-plumbing. Matloana a silicone e hlahisoang ke khamphani ea rona e kopana le litekanyetso tsa ts'ireletso ea tikoloho ea EU le maemo a lichelete tsa EU tsa lijo
Nitrile rabara ke polymer e fumanoang ka emulsion copolymerization ea butadiene le acrylonitrile. E tsebahala ka ho tsuba ha eona ka oli, hape e na le botle ba ho hanyetsa, botsofali le ho thibela moea, ho loantša ho apara le ho otlolla. E sebelisoa liketsong tse sa tšoaneng tsa indasteri ea rabara. Melemo: NBR e nolofalletsa ho hanyetsa le ho hanyetsa habonolo ho foqoha ha metsi, ho teteka, ho taboha le ho senya.
Fluororubber gasket e na le mocheso o phahameng oa mocheso 'me o ka sebelisoa moeeng oa 20 ° C- + 200 ° C. E thata ho li-oxidants tse matla, oli le acid le alkaline. Hangata e sebelisoa ka mocheso o phahameng, libaka tse phahameng tsa khatello le khatello, mme e boetse e loketse libaka tsa mafura. Ka lebaka la ts'ebetso ea eona e babatsehang, fluororubber e sebelisoa hohle ka oli ea peterole, lik'hemik'hale, sebaka sa marulelo a marulelo, sebaka sa marulelo le likarolo tse ling.
Mofuta o mong oa li-neoprene, rabara ea tlhaho, rabara ea EPDM, rabara ea acrylate le li-rubber tse ling tse khethehileng. E khahlanong le oli, acid, alkali, abrasion, mocheso o phahameng le o tlase.
Ha e fane feela ka batho ba nang le lihlahisoa tsa rabara tse sebetsang ka letsatsi le letsatsi le lihlahisoa tsa meriana tseo e leng tsa bohlokoa bakeng sa bophelo ba letsatsi le leng le le leng, empa hape ba fana ka lisebelisoa tse ngata tsa ho hlahisa rabara kapa likarolo tsa lirapa liindastering tse boima le indasteri e tsoelang pele e kang merafo, lipalangoang, kahong le elektronike. Ho ka bonoa hore ho na le mefuta e mengata ea lihlahisoa indastering ea rabara, mme indasteri ea morao e pharaletse haholo.
