Caagga EPDM (EPDLELELELELELELELELI DIETOMER Monomer caag) waa nooc caag ah oo lagu isticmaalo codsiyo badan. Dienes loo adeegsaday soo saarista EPDM Folds waa Ethylidenne ama dhalane (enBlopentadiene (DCPDCLENENENE (DCPD), iyo Vinyl ama Vinyl (VNB). 4-8% monomes-yadaan ayaa caadi ahaan loo isticmaalaa. EPDM waa caag-heerka M-CLASS ee hoos timaada astm Standard D-1418; Heerka M wuxuu ka kooban yahay emastomers haysta silsilad buuq leh oo ah nooca polyetylen (oo laga soo saaro ereyga saxda ah ee ereyga saxda ah). EPDM waxaa laga sameeyay ethylene, Propylene, iyo koloniinta Diene ah oo u sahleysa iskutallaabta iyada oo loo marayo nuqulka rcation. EPDM EpDM waa EPR, Propylement Propillement (waxtar leh ee fiilooyinka korantada ee korantada), oo aan laga soo qaadan wax kasta oo diene ah oo keliya ayaa laga gudbin karaa iyadoo la adeegsanayo qaabab xagjir ah sida aragtida xagjirka ah.
Sida ugu badan ee loo yaqaan 'Epdm', EPDM waxaa had iyo jeer loo isticmaalaa isku xirnaanta sida kaarboon madow iyo kaalshiyamka kaalshiyamka ah, oo leh balaarro ah sida paraffins-ka sida paraffins-ka sida paraffins-ka oo keliya marka la gooyo. Isku-darka guud ahaan waxay ka dhacdaa caqabad ku ah baaruud, laakiin sidoo kale waxaa lagu dhammeeyaa cod-bixiyeyaal (si loogu helo iska caabbinta kuleylka wanaagsan) ama sadarka phenolic. Shucaaca tamarta sare sida laga soo bilaabo alwaaxyada elektaroonigga ah waxaa mararka qaarkood loo isticmaalaa soo saarida xumbooyinka iyo silig iyo fiilo.
