Irabha ye-ethylene propylene iyirabha yokwenziwa ene-ethylene ne-propylene njengama-monomers ayinhloko. Ngokusho kokwakhiwa kwama-monomers ochungechungeni lwamangqamuzana, ingahlukaniswa ibe yi-ethylene propylene diene monomer ne-ethylene propylene diene monomer. Eyokuqala iyi-copolymer ye-ethylene ne-propylene, evezwe njenge-EPM, kanti lena yokugcina iyi-copolymer ye-ethylene, i-propylene kanye nenani elincane le-nonconjugated diene lesithathu monomer, evezwe njenge-EPDM. Zombili zibizwa ngokuhlanganyela njengerabha ye-ethylene propylene.
Inokumelana okuhle namakhemikhali e-polar ahlukahlukene njengotshwala, i-asidi, i-alkali, i-oxidant, isiqandisi, okokuhlanza, amafutha ezilwane nemifino, i-ketone namafutha; Kodwa-ke, inokungaqini kahle kwezinyibilikisi ze-aliphatic nezinephunga elimnandi (ezifana nophethiloli, benzene, njll.) namafutha amaminerali. Ngaphansi kwesenzo se-asidi egxilile isikhathi eside, ukusebenza kuzokwehla. Isetshenziswa kabanzi ezingxenyeni zemoto, izinto ezingangeni manzi zokwakha, izintambo zezintambo nezintambo, ipayipi elingashisi ukushisa, i-adhesive tape, izimpawu zezimoto, izithasiselo zikawoyela zokugcoba neminye imikhiqizo.
