Re ka qala ka litaba tsa dieene.Ho hanyetsa boemo ba leholimo ba rabara ea EPDM ho amana le li-unsaturated bond tse peli tse dienes.Ha litaba tsa dienes li fokotseha, ho hanyetsa boemo ba leholimo ba liphaephe tsa rabara tsa EPDM ho eketseha butle-butle.Kahoo khetha li-hoses tse nang le dikahare tse tlase tsa diene ha u reka.
Ho phaella moo, li-fillers tse ling, tse kang carbon black, li ka kenyelletsoa lihlahisoa tse tala ha li etsa li-hose tsa EPDM.Carbon black e hanyetsana haholo le mahlaseli a UV 'me e ka monya mahlaseli a UV ho isa bohōleng bo itseng.Ho feta moo, likaroloana tse nyenyane tsa carbon black le palo e kholo ea carbon black e ekelitsoeng, ho matlafala ho hanyetsa boemo ba leholimo ba hose e hlahisoang ea EPDM.Leha ho le joalo, sena se ka sebelisoa feela ha ho etsoa li-tubes tse ntšo, tse lefifi tsa rabara.
Re 'nile ra tsepamisa maikutlo tlhahisong ea lihlahisoa tsa rabara le tsa polasetiki tse kang li-sleeve spiral protective, liphaephe tsa metsi tse tlaase tsa EPDM, liphaephe tsa oli tse tlaase tsa NBR nitrile, le li-strip tse tiisang lilemo tse 30.Re na le lilemo tse 30 tsa boiphihlelo ba tlhahiso mme re ka etsa lihlahisoa ho latela litlhoko tsa hau.Rea u amohela Tlo ho botsa.
