Zvakanakira uye zvisingabatsiri zvePDM hose: kuchembera kuramba, kuvharwa kwemagetsi uye kupikisa ozone kwakatanhamara.Yakanakisa yemamiriro ekunze kuramba, ozone kuramba, kupisa kupisa, asidhi uye alkali kuramba, mvura mhute kuramba, kugadzikana kwemavara, zvivakwa zvemagetsi, zvivakwa zvekuzadza mafuta uye tembiricha yekamuri.Detergents, mhuka nemafuta emiriwo, ketoni uye magirisi zvose zvine kumira zvakanaka;asi vane kusagadzikana kwakashata mumafuta uye zvinonyungudutsa zvinonhuhwirira (sepeturu, benzene, nezvimwewo) nemafuta emamineral.Pasi pechiito chenguva refu cheiyo yakanyungudutswa asidhi, kuita kunozodzikisawo mhute yemvura uye inofungidzirwa kuve nani pane kupisa kwayo.Mu230 ℃ superheated steam, hapana shanduko muchitarisiko mushure menguva ingangoita 100h.Asi pasi pemamiriro akafanana, rabha yefluorine, silicon rabha, fluorine silicon rabha, butyl rabha, nitrile rabha, uye rabha rechisikigo zvakaona kuderera kuri pachena pakuonekwa mushure menguva pfupi.Nekuti hapana polar inotsiva muchimiro chemolecular ye ethylene-propylene rubber, iyo yakabatana simba remorekuru yakaderera, uye cheni yemamorekuru inogona kuchengetedza kuchinjika muhupamhi, yechipiri chete kune yakasikwa rubber uye butadiene rubber, uye inogona kuramba iripo. inochengetedzwa pakudziya kwakaderera.Ethylene-propylene rabha inoshaya mapoka anoshanda nekuda kwechimiro chayo chemolecular, ine simba rakabatana rakaderera, uye rabha iri nyore kutumbuka, uye kunamatira kwayo uye kubatana kwayo kune hurombo zvakanyanya.
