Rubber o-mhete EPDM 70shore-A FDA chikafu chegiredhi
● Kazhinji, EPDM o-rings dzinozivikanwa kuti dzine kupikisa kwakanakisisa ku ozone, chiedza chezuva, uye mamiriro ekunze, uye ine kushanduka kwakanaka kwazvo pakudzika kwekushisa, kupikisa kwakanaka kwemakemikari (akawanda dilute acids uye alkalis pamwe ne polar solvents), uye magetsi akanaka ekudzivirira. pfuma.
● EPDM o-rings inogonawo kuuya mune imwe simbi inooneka kusiyana ichichengetedza hunhu hwakafanana neyakajairwa EPDM o-ring compound.EPDM o-rings anowanzova matema muruvara, ane sherufu yenguva refu.Cure System: Peroxide- Yakaporeswa Standard EPDM o-ring compounds inowanzo rapwa nesarufa.
● Sulfur-cured compounds inopa zvinhu zviri nani zvinogadziriswa asi zvinonyanya kuoma uye zvine dhigirii yakaderera yakagadziriswa nekushisa kwepamusoro.Peroxide-yakagadziriswa EPDM o-ring compounds ine zviri nani kupisa kupisa uye kutsika kwepasi.Inopindirana nekushandiswa kwenguva refu. , kunyanya kune zvirongwa zvepombi mumhizha yekuvaka, asi inodhura uye yakaoma zvikuru pakugadzirwa kupfuura sulfur-yakagadziriswa EPDM o-ring compounds.
● Kuti uwane rumwe ruzivo nezve EPDM kurapa masisitimu, ndapota wakasununguka kutibata kuti uwane ruzivo rwebepa.
● EPDM O-Ring Temperature Range: Standard Low Temp: -55°C (-67°F)
● Standard High Temp: 125°C (257°F) Inoita Zvakanaka Mu: Doro Mota yebhureki fluid Ketones Dilute acids nealkalis Silicone oiri negirisi Kupisa kusvika ku204.4ºC (400ºF) Mvura Phosphate ester based hydraulic fluids Ozone, kuchembera, uye mamiriro ekunze. .
● chii chimwe, EPM iCopolymer ye ethylene uye propylene.EPDM inonzi terpolymer ye ethylene uye propylene ine kashoma ketatu monoma (kazhinji diolefin) kubvumira vulcanization nesarufa.
● Kazhinji Ethylene Propylene Rubber inokwanisa kurwisana neozone, chiedza chezuva uye mamiriro ekunze, uye ine flexible yakanaka kwazvo pakudziya kwakadzikama, good chemical resistance (yakawanda dilute acids, alkalis & polar solvents), uye zvinhu zvakanaka zvekudzivirira magetsi.
● Shore-A:Kubva 30-90 kumahombekombe-A chero ruvara runogona kuita.
● SIZE:AS-568 saizi yese.
