I-ethylene propylene rubber (ikakhulukazi kanambambili ethylene propylene ruble) isetshenziswa ngamanani amakhulu njenge-viscosity inkomba ukuguqula (ovi noma i-vii) ukuthuthukisa amafutha amaningi ezindaweni zokushisa eziphakeme namazinga aphansi futhi ukuze ugcwalise amafutha asebenze kangcono kwazo zombili ezimweni eziqinile nezinamandla.
I-ethylene propylene rubber idinga amandla aphezulu okuqina, iphuzu eliphansi lokuthulula kanye nenkomba yokuqina ye-shear ephansi lapho isetshenziswa njengesengezo se-modifier sokulungiselela, uphethiloli kanye nodizili.
