Rubber o-mphete EPDM 70shore-A FDA chakudya kalasi
● Nthawi zambiri, mphete za EPDM zimadziwika kuti zimakhala ndi mphamvu zolimbana ndi ozoni, kuwala kwa dzuwa, ndi nyengo, ndipo zimakhala bwino kwambiri pa kutentha kochepa, kukana kwa mankhwala (ma acid ambiri a dilute ndi alkalis komanso zosungunulira za polar), komanso kutsekemera kwamagetsi kwabwino. katundu.
● EPDM o-rings amathanso kubwera muzitsulo zowoneka bwino pamene akusungabe makhalidwe omwewo monga EPDM o-ring compound.EPDM o-ringing nthawi zambiri imakhala yakuda, yokhala ndi alumali yokhalitsa.Cure System: Peroxide- Curred Standard EPDM o-ring mankhwala nthawi zambiri amachiritsidwa ndi sulfure.
● Mankhwala opangidwa ndi sulfure amapereka zinthu zosinthika bwino koma zimakhala zovuta kwambiri komanso zimakhala ndi zochepetsera zochepa zomwe zimakhala ndi kutentha kwakukulu.Zosakaniza za EPDM o-ring za peroxide zimakhala ndi kutentha kwabwino komanso kutsika kwapansi. , makamaka kwa machitidwe a payipi m'makampani omangamanga, koma ndi okwera mtengo komanso ovuta kupanga kusiyana ndi sulfure ochiritsidwa EPDM o-ring compounds.
● Kuti mudziwe zambiri zokhudza EPDM cure systems, chonde titumizireni kwaulere kuti mudziwe zambiri.
● EPDM O-Ring Kutentha Kwambiri: Kutsika Kwambiri: -55°C (-67°F)
● Kutentha Kwambiri Kwambiri: 125°C (257°F) Kumachita Bwino Mu:Mowa Ma brake fluid Magalimoto Ketoni Amasungunula ma acid ndi alkali Mafuta a Silicone ndi mafuta Kutentha mpaka 204.4ºC (400ºF) Madzi Phosphate ester based hydraulic fluids Ozone, kukalamba, ndi nyengo. .
● Kuonjezera apo, EPM ndi Copolymer ya ethylene ndi propylene.EPDM ndi terpolymer ya ethylene ndi propylene yokhala ndi kachulukidwe kakang'ono kachitatu (kawirikawiri diolefin) kulola vulcanization ndi sulfure.
● Nthawi zambiri Rubber wa Ethylene Propylene umakhala ndi mphamvu yolimbana ndi ozoni, kuwala kwa dzuwa ndi nyengo, ndipo umasinthasintha bwino pa kutentha kochepa, kukana kwa mankhwala (ma acid ambiri osungunuka, alkalis & polar solvents), ndi mphamvu zabwino zotetezera magetsi.
● Shore-A:Kuchokera ku 30-90 gombe-A mtundu uliwonse ukhoza kuchita.
● SIZE:AS-568 kukula konse.
