Rubber ya EPDM (Ethylene propylene diene monomer rubber) ni ubwoko bwa reberi yubukorikori ikoreshwa mubikorwa byinshi.Diène ikoreshwa mugukora reberi ya EPDM ni Ethylidene norbornene (ENB), dicyclopentadiene (DCPD), na vinyl norbornene (VNB).4-8% by'aba monomers bakunze gukoreshwa.EPDM ni rubber yo mu rwego rwa M munsi ya ASTM isanzwe D-1418;icyiciro cya M kigizwe na elastomers ifite urunigi rwuzuye rwubwoko bwa polyethylene (M ikomoka kumagambo meza ya polymethylene).EPDM ikozwe muri Ethylene, propylene, na diene comonomer ituma habaho guhuza binyuze mumashanyarazi ya sulfuru.Umuvandimwe wa mbere wa EPDM ni EPR, reberi ya Ethylene propylene (ifasha insinga z'amashanyarazi zifite ingufu nyinshi), ntabwo ikomoka kubibanjirije diene kandi irashobora guhuzwa gusa hakoreshejwe uburyo bukabije nka peroxide.
Kimwe na reberi nyinshi, EPDM ikoreshwa buri gihe hiyongereyeho ibyuzuzo nka karubone yumukara na calcium karubone, hamwe na plasitike nkamavuta ya paraffinike, kandi ifite akamaro ka rubberi gusa iyo bihujwe.Guhuza ahanini bikorwa binyuze muri volcanisation hamwe na sulfure, ariko kandi bigakorwa na peroxide (kugirango irusheho guhangana nubushyuhe) cyangwa hamwe na fenolike.Imirasire yingufu nyinshi nko kuva kumirasire ya electron rimwe na rimwe ikoreshwa mugukora ifuro ninsinga na kabili.
