ʻO ka ethylene propylene rubber he lāʻau synthetic me ka ethylene a me propylene e like me nā monomers nui. E like me ka hoʻohui ʻana o nā monomers i loko o ke kaulahao mole, hiki ke hoʻokaʻawale ʻia i ka ethylene propylene diene monomer a me ka ethylene propylene diene monomer. ʻO ka mea mua he copolymer o ka ethylene a me ka propylene, i hōʻike ʻia ma ke ʻano he EPM, aʻo ka mea hope he copolymer o ka ethylene, propylene a me kahi mea liʻiliʻi o ka monomer diene kolu ʻole, i hōʻike ʻia ma ke ʻano he EPDM. Ua kapa ʻia nā mea ʻelua he ethylene propylene rubber.
He kūpaʻa maikaʻi ia i nā kinikini polar like ʻole e like me ka waiʻona, ka waikawa, ka alkali, ka mea hoʻoheheʻe, ka refrigerant, ka mea holoi, ka aila holoholona a me ka ʻaila, ketone a me ka momona; Eia nō naʻe, ʻaʻohe paʻa i nā aliphatic a me nā mea hoʻoheheʻe ʻala (e like me ka ʻaila, benzene, etc.) a me nā aila mineral. Ma lalo o ka hana o ka acid concentrated no ka manawa lōʻihi, e emi ana ka hana. Hoʻohana nui ʻia ia i nā ʻāpana kaʻa, nā mea wai ʻole no ke kūkulu ʻana, nā uea a me nā kaula uwea, ka hose pale wela, ka lipine adhesive, nā sila kaʻa, nā mea hoʻohui aila lubricating a me nā huahana ʻē aʻe.
