Incazelo emfushane:

Izinzuzo kanye nokubi kwe-PDM hose: ukumelana nokuguga, ukufakwa kukagesi nokumelana ne-ozone kuvelele.Ukumelana nesimo sezulu esihle kakhulu, ukumelana ne-ozone, ukumelana nokushisa, ukumelana ne-asidi ne-alkali, ukumelana nomhwamuko wamanzi, ukuzinza kombala, izakhiwo zikagesi, izakhiwo zokugcwalisa uwoyela kanye nokushisa kwegumbi.Izihlanzi, amafutha ezilwane nemifino, ama-ketone namafutha anamafutha anamandla okumelana nezifo;kodwa azinzinzi kahle ezincibilikisini ezinamafutha nezinuka kamnandi (ezifana nophethiloli, ibenzene, njll.) namafutha amaminerali.Ngaphansi kwesenzo sesikhathi eside se-asidi egxilile, ukusebenza kuzophinde kunciphise ukumelana nomhwamuko wamanzi futhi kulinganiselwa ukuthi kungcono kunokumelana nokushisa kwawo.Ku-230 ℃ umusi oshisa kakhulu, alukho ushintsho ekubukekeni ngemva cishe kwamahora angu-100.Kodwa ngaphansi kwezimo ezifanayo, irabha ye-fluorine, irabha ye-silicon, irabha ye-silicon ye-fluorine, irabha ye-butyl, irabha ye-nitrile, nerabha yemvelo kwaba nokuwohloka okusobala kokubukeka ngemva kwesikhathi esifushane.Ngenxa yokuthi awekho ama-substituents we-polar esakhiweni samangqamuzana enjoloba ye-ethylene-propylene, amandla ahlangene we-molecule aphansi, futhi iketango lamangqamuzana lingakwazi ukugcina ukuguquguquka kwezinto ezihlukahlukene, okwesibili kuphela kwerabha yemvelo kanye nerabha ye-butadiene, futhi isengaba. igcinwe emazingeni okushisa aphansi.Irabha ye-ethylene-propylene ayinawo amaqembu asebenzayo ngenxa yesakhiwo sayo samangqamuzana, inamandla amancane ahlangene, futhi irabha kulula ukuqhakaza, futhi ukunamathela kwayo kanye nokunamathelana kwayo kubi kakhulu.
