Irabha o-amakhonkco EPDM 70shore-A FDA ibakala lokutya
● Ngokubanzi, amakhonkco e-EPDM ayaziwa ngokukwazi ukumelana ne-ozone, ukukhanya kwelanga, kunye nemozulu, kwaye anokuguquguquka okuhle kakhulu kwiqondo lobushushu eliphantsi, ukuxhathisa okulungileyo kwimichiza (amaninzi e-dilute acids kunye neealkali kunye nezinyibiliki ze-polar), kunye nokufakelwa kombane okulungileyo. impahla.
● I-EPDM i-o-rings inokuthi iphinde ifike kwi-metal detectable variation ngelixa igcina iimpawu ezifanayo njenge-EPDM o-ring compound.EPDM o-rings ngokuqhelekileyo banombala omnyama, kunye ne-shelf ehlala ixesha elide.Cure System: Peroxide- I-Cured Standard EPDM o-ring compounds idla ngokunyangwa ngesulfure.
● Iikhompawundi ze-sulfure ezixutywe nge-sulfure zibonelela ngeempawu eziguquguqukayo ezingcono kodwa ziyakwazi ukuqina kwaye zibe ne-inferior compression set with high temperatures.I-Peroxide-cured EPDM o-ring compounds inokumelana nobushushu obungcono kunye ne-compression compression set.Ihambelana nokusetyenziswa kwexesha elide. , ngakumbi kwiinkqubo ze-hose kushishino lokwakha, kodwa kubiza kakhulu kwaye kunzima kakhulu kwimveliso kune-sulfur-cured EPDM o-ring compounds.
● Ukuze ufumane inkcazelo engakumbi ngeenkqubo zokunyanga ze-EPDM, nceda ukhululeke ukuqhagamshelana nathi ukuze ufumane iinkcukacha zephepha.
● I-EPDM O-Ring Uluhlu lobushushu: Ubushushu obuPhantsi obuMgangatho: -55°C (-67°F)
● Ubushushu obuMgangatho obuPhakathi: 125°C (257°F) Isebenza Kakuhle Ku: Utywala I-Automotive brake fluid Ketones Dilulula iiasidi kunye nealkali Ioli yeSilicone namafutha greasi Umphunga ukuya kutsho kuma-204.4ºC (400ºF) Amanzi Phosphate ester esekwe kulwelo lwehydraulic Ozone, ukuguga, kunye nemozulu. .
● ngaphezu koko, i-EPM yiCopolymer ye-ethylene kunye nepropylene.I-EPDM yi-terpolymer ye-ethylene kunye ne-propylene kunye nenani elincinci le-monomer yesithathu (ngokuqhelekileyo i-diolefin) ukuvumela i-vulcanization ngesulfure.
● Ngokubanzi Irabha ye-Ethylene Propylene inamandla okumelana ne-ozone, ukukhanya kwelanga kunye nemozulu, kwaye inokuguquguquka okuhle kakhulu kwiqondo lobushushu eliphantsi, ukuxhathisa okulungileyo kwiikhemikhali (ezininzi ze-acids ezixubileyo, i-alkalis & nezinyibilikisi ze-polar), kunye neempawu ezilungileyo zokugquma umbane.
● Unxweme-A:Ukususela kwi-30-90 yolwandle-A nawuphi na umbala onokuyenza.
● SIZE:AS-568 bonke ubukhulu.
