Singaqala kusukela kokuqukethwe kwe-diene.Ukuphikiswa kwesimo sezulu kwerabha ye-EPDM kuhlobene nalawo mabhondi ayi-unsaturated double angama-dienes.Njengoba okuqukethwe kwe-dienes kuncipha, ukumelana nesimo sezulu samapayipi enjoloba e-EPDM kukhula kancane kancane.Ngakho-ke khetha lawo mapayipi anokuqukethwe okuphansi kwe-diene uma uthenga.
Ngaphezu kwalokho, amanye ama-filler, afana ne-carbon black, angangezwa ezintweni zokusetshenziswa lapho kwenziwa ama-hoses e-EPDM.I-Carbon black imelana kakhulu nemisebe ye-UV futhi ingamunca imisebe ye-UV ngokwezinga elithile.Ngaphezu kwalokho, izinhlayiya ezimnyama zekhabhoni ezincane kanye nenani elikhulu lekhabhoni elimnyama elingeziwe, kunamandla ukumelana nesimo sezulu sepayipi elikhiqiziwe le-EPDM.Nokho, lokhu kungasetshenziswa kuphela lapho kukhiqizwa amashubhu erabha amnyama, amnyama.
I-coqi ibigxile ekukhiqizeni imikhiqizo yenjoloba nepulasitiki efana nemikhono evikelayo evunguzayo, amapayipi amanzi anomfutho ophansi we-EPDM, amapayipi kawoyela we-NBR nitrile anengcindezi ephansi, kanye nemicu yokuvala iminyaka engu-30.Sineminyaka engu-30 yokuhlangenwe nakho kokukhiqiza futhi singenza ngokwezifiso imikhiqizo ngokuvumelana nezidingo zakho.Wamukelekile Woza uzobuza.
