Tikhoza kuyambira zomwe zili mu diene.Kukaniza kwanyengo kwa rabara ya EPDM kumagwirizana ndi zomangira ziwiri zopanda unsaturated zomwe ndi dienes.Pamene zomwe zili mu dienes zimachepetsa, kukana kwa nyengo kwa mapaipi a rabara a EPDM kumawonjezeka pang'onopang'ono.Chifukwa chake sankhani ma hoses omwe ali ndi zinthu zochepa za diene pogula.

Kuphatikiza apo, zodzaza zina, monga kaboni wakuda, zitha kuwonjezeredwa kuzinthu zopangira popanga ma hose a EPDM.Mpweya wakuda umalimbana kwambiri ndi kuwala kwa UV ndipo umatha kuyamwa cheza cha UV mpaka pamlingo wina wake.Komanso, tinthu tating'onoting'ono ta kaboni wakuda komanso kuchuluka kwa mpweya wakuda wowonjezera, kumapangitsa kuti paipi ya EPDM ikhale yolimba kwambiri.Komabe, izi zitha kugwiritsidwa ntchito popanga machubu akuda, mphira wakuda.

We conqi takhala tikuyang'ana kwambiri pakupanga mphira ndi zinthu zapulasitiki monga manja oteteza ozungulira, mapaipi amadzi otsika a EPDM, mapaipi amafuta a NBR nitrile otsika, ndi mizere yosindikiza kwa zaka 30.Tili ndi zaka 30 zopanga ndipo titha kusintha zinthu malinga ndi zomwe mukufuna.Takulandirani Bwerani ndikufunseni.
