Roj hmab o-rings EPDM 70shore-A FDA zaub mov qib
● Feem ntau, EPDM o-rings paub tias muaj kev tiv thaiv zoo heev rau ozone, tshav ntuj, thiab huab cua, thiab muaj qhov hloov tau zoo heev ntawm qhov kub thiab txias, zoo tshuaj tiv thaiv (ntau cov kua qaub thiab alkalis nrog rau cov kuab tshuaj polar), thiab zoo hluav taws xob rwb thaiv tsev. vaj tse.
● EPDM o-rings kuj tuaj yeem tuaj yeem muaj qhov sib txawv ntawm cov hlau thaum khaws cov khoom zoo ib yam li EPDM o-ring compound.EPDM o-rings feem ntau yog xim dub, nrog rau lub txee lub neej ntev.Cure System: Peroxide- Kho Standard EPDM o-ring compounds feem ntau yog sulfur-kho.
● Sulfur-kho cov tebchaw muab cov khoom hloov pauv tau zoo dua tab sis muaj ntau dua rau kev ua kom tawv thiab muaj qhov qis qis qis nrog qhov kub thiab txias.Peroxide-kho EPDM o-ring compounds muaj cua sov zoo dua thiab qis dua compression.It ua raws li kev siv sijhawm ntev. , tshwj xeeb tshaj yog rau hose systems nyob rau hauv kev tsim kho kev lag luam, tab sis yog kim kim thiab nyuaj rau ntau lawm ntau tshaj li sulfur-kho EPDM o-ring tebchaw.
● Yog xav paub ntxiv txog EPDM kho tshuab, thov hu rau peb kom paub meej daim ntawv.
● EPDM O-Ring Kub Kub Ntau Yam: Txheem Tsawg Kub: -55 ° C (-67 ° F)
● Standard High Temp: 125°C (257°F) Ua tau zoo nyob rau hauv: Dej cawv Automotive nres kua Ketones Dilute acids thiab alkalis Silicone roj thiab greases Chav mus txog 204.4ºC (400ºF) Dej Phosphate ester raws li hydraulic kua Ozone, laus, thiab huab cua .
● Dab tsi ntxiv, EPM yog Copolymer ntawm ethylene thiab propylene.EPDM yog terpolymer ntawm ethylene thiab propylene nrog me me ntawm peb lub monomer (feem ntau yog diolefin) tso cai rau vulcanization nrog sulfur.
● Feem ntau Ethylene Propylene Roj Hmab muaj kev tiv thaiv zoo heev rau ozone, tshav ntuj thiab huab cua, thiab muaj qhov hloov tau zoo heev ntawm qhov kub thiab txias, zoo tshuaj tiv thaiv (ntau cov kua qaub, alkalis & polar solvents), thiab cov khoom siv hluav taws xob zoo.
● Shore-A:Los ntawm 30-90 ntug dej-A txhua yam xim tuaj yeem ua.
● SIZE:AS-568 tag nrho qhov loj.
