Iinzuzo kunye nokungonakali kwe-hose ye-PDM: ukuchasana nokuguga, ukugquma kombane kunye nokuxhatshazwa kwe-ozone kubalaseleyo.Ukumelana nemozulu egqwesileyo, ukuxhathisa kwe-ozone, ukumelana nobushushu, ukuxhathisa kwe-asidi kunye ne-alkali, ukuxhathisa umphunga wamanzi, ukuzinza kombala, iipropati zombane, iipropati zokuzaliswa kweoli kunye nobushushu begumbi.Izicoci, ioyile yezilwanyana kunye nemifuno, iiketones kunye negrisi zonke zinokuxhathisa okulungileyo;kodwa azinzi kakuhle kwizinyibilikisi ezinamafutha neziqholo (ezifana nepetroli, ibenzene, njl. njl.) kunye ne-mineral oils.Ngaphantsi kwesenzo sexesha elide le-asidi egxininisiweyo, ukusebenza kuya kunciphisa ukuxhathisa komphunga wamanzi kwaye kuqikelelwa ukuba kungcono kunokumelana nobushushu.Kwi-230℃ umphunga oshushu kakhulu, akukho tshintsho kwinkangeleko emva kwe-100h.Kodwa phantsi kweemeko ezifanayo, irabha ye-fluorine, irabha yesilicon, irabha ye-fluorine yesilicon, irabha ye-butyl, irabha ye-nitrile, kunye nerabha yendalo ziye zafumana ukuwohloka okucacileyo kwenkangeleko emva kwexesha elifutshane.Ngenxa yokuba akukho zixhobo ze-polar kwisakhiwo se-molecular ye-rubber ye-ethylene-propylene, amandla adibeneyo e-molecule aphantsi, kwaye i-molecular chain chain ingakwazi ukugcina ukuguquguquka kuluhlu olubanzi, okwesibini kuphela kwi-rubber yendalo kunye ne-butadiene irabha, kwaye isenakho. igcinwe kumaqondo aphantsi.Irabha ye-ethylene-propylene ayinamaqela asebenzayo ngenxa yesakhiwo sayo semolekyuli, inamandla aphantsi adibeneyo, kwaye irabha ilula ukuqhakaza, kwaye ukunamathela kwayo kunye nokunamathelana kwayo kubi kakhulu.
