Triple propylene roba (EPDM) ne da aka yi da ethylene, propylene monomer da ƙananan adadin non-conjugated diolene polymer. Tsarinsa yana da siffofin ba tare da haɗin biyu ba a kan manyan sarkar kwayoyin polymer, yayin da aka gabatar da haɗin biyu ba a kan sarkar rassa. Saboda haka yana da kyakkyawan yanayi juriya, zafi juriya, ozone juriya, UV juriya da kuma kyakkyawan aiki da low matsa karkatarwa, shi ne samar da kayan hatimi bar. A halin yanzu, mafi yawan kayan hatimin mota suna amfani da EPDM a matsayin babban albarkatun kasa.
