Ethylene propylene rabara ndi mphira wopangidwa ndi ethylene ndi propylene monga ma monomers akulu. Malinga ndi mapangidwe a monomers mu unyolo wa maselo, amatha kugawidwa mu ethylene propylene diene monomer ndi ethylene propylene diene monomer. Yoyamba ndi copolymer ya ethylene ndi propylene, yofotokozedwa ngati EPM, pamene yotsirizirayi ndi copolymer ya ethylene, propylene ndi pang'ono chabe ya non conjugated diene third monomer, yofotokozedwa ngati EPDM. Onse pamodzi amatchedwa ethylene propylene rabara.
Ili ndi kukana bwino kwa mankhwala osiyanasiyana a polar monga mowa, asidi, alkali, okosijeni, refrigerant, detergent, nyama ndi mafuta a masamba, ketone ndi mafuta; Komabe, ili ndi kusakhazikika bwino mu zosungunulira za aliphatic ndi zonunkhira (monga mafuta, benzene, etc.) ndi mafuta amchere. Pansi pa zochita za asidi wambiri kwa nthawi yayitali, ntchitoyo idzachepanso. Amagwiritsidwa ntchito kwambiri m'zigawo zamagalimoto, zida zopanda madzi pomanga, waya ndi zingwe zopangira chingwe, payipi yosagwira kutentha, tepi yomatira, zisindikizo zamagalimoto, zopangira mafuta opaka mafuta ndi zinthu zina.
