(2) Physical and mechanical properties: most oil-resistant rubber due to low tensile strength, so it limits the scope of its application, such as FKM tensile strength of 19.6-21.6MPa, HNBR strength than NBR, ACMXNBR, EPDM and FKM and other types of rubber are higher, such as Zeon ZSC hydrogenated nitrile butadiene lastikuw sɔgɔli fanga fo ka se 6OMPa ma min nafa ka bon kosɛbɛ, o ye ko HNBR min bɛ funteni caman na ( Min nafa ka bon kosɛbɛ, HNBR min bɛ funteni caman na ( 15O °C ) fanga jukɔrɔ ( 14,7-29.4MPa ) ani so funteni NBR walasa ka hakɛ kelen mara funteni caman na tulu gɛlɛn suguya caman na ani kemikɛlifɛnw na, o bɛ se ka masinko jogo ɲumanw mara hali bi, funteni caman na ani masinko cogoyaw bɛ fisaya ni elastic ah farikolo tɔw fanba ye, abrasion resistance ɲuman Trough appropriate matching
