Ethylene propylene roj hmab yog cov roj hmab hluavtaws nrog ethylene thiab propylene ua lub ntsiab monomers. Raws li muaj pes tsawg leeg ntawm monomers hauv cov saw hlau molecular, nws tuaj yeem muab faib ua ethylene propylene diene monomer thiab ethylene propylene diene monomer. Lub qub yog ib tug copolymer ntawm ethylene thiab propylene, qhia raws li EPM, thaum lub tom kawg yog ib tug copolymer ntawm ethylene, propylene thiab ib tug me me ntawm tsis conjugated diene thib peb monomer, qhia raws li EPDM. Ob leeg raug hu ua ethylene propylene roj hmab.
Nws muaj kev tiv thaiv zoo rau ntau yam tshuaj polar xws li cawv, kua qaub, alkali, oxidant, tub yees, detergent, tsiaj thiab zaub roj, ketone thiab roj; Txawm li cas los xij, nws muaj kev ruaj ntseg tsis zoo hauv aliphatic thiab cov kuab tshuaj tsw qab (xws li roj av, benzene, thiab lwm yam) thiab cov roj ntxhia. Nyob rau hauv qhov kev txiav txim ntawm concentrated acid rau lub sij hawm ntev, qhov kev ua tau zoo kuj yuav poob. Nws yog dav siv nyob rau hauv tsheb qhov chaw, cov ntaub ntawv waterproof rau kev tsim kho, hlau thiab cable sheaths, tshav kub-resistant hose, nplaum daim kab xev, tsheb ntsaws ruaj ruaj, lubricating roj additives thiab lwm yam khoom.
