I-EPDM RUBBER (i-Ethylene Propellene Dieen Monomer Rubber) uhlobo lokwakheka kwerabha olusetshenziswa kuzinhlelo eziningi. UDieenes usetshenziselwe ekwenziweni kwama-rubs e-EPDM yi-EthyLidene Normbene (ENB), I-DCPD), ne-DCPD), neVenb Norvene (VNB). I-4-8% yalawa ma-monomers asetshenziswa ngokujwayelekile. I-EPDM iyinjoloba ye-M-CLASS ngaphansi kwe-ASTM ejwayelekile D-1418; Ikilasi le-M lihlanganisa ama-lastomers aneqoqo eligcwele le-polyethylene (the m asuselwa ku-polymethylene). I-EPDM yenziwa nge-ethylene, i-propylene, kanye ne-comonoming ye-diene enika amandla ukuwela i-sulfur Vulcanization. Isihlobo sangaphambilini se-EPRM yi-EPR, i-Ethylene Propelene Rubber (ewusizo kumakhekhe kagesi aphezulu), lokho akutholwa kunoma yimuphi owedlule we-Diene Preserron futhi kungancipha kuphela kusetshenziswa izindlela ezinamandla njenge-peroxides.
Njengama-rubbers amaningi, i-EPDM ihlala isetshenziswa ihlanganiswe nabasizi njengekhabhoni emnyama ne-calcium Carbonate, ngama-spipisis afana namafutha e-paraffic, futhi inezakhiwo eziwusizo zerejista kuphela lapho zinqamule. Ukuwela kakhulu kwenzeka nge-Vulcanation nge-sulcur, kepha kufezeka nge-peroxides (ngokumelana nokushisa okungcono) noma nge-phenolic resins. Imisebe ye-High-Energy enjengemigqa ye-elekthron kwesinye isikhathi isetshenziselwa ukukhiqiza amagwebu nocingo nekhebula.
