Rubber o-rings EPDM 70shore-A FDA kereiti ea lijo
● Ka kakaretso, li-o-rings tsa EPDM li tsejoa hore li na le khanyetso e babatsehang ea ozone, khanya ea letsatsi le boemo ba leholimo, 'me li na le ho fetoha ha maemo ha mocheso o tlaase, lik'hemik'hale tse ntle tsa lik'hemik'hale (li-acid tse ngata tsa dilute le alkali hammoho le li-solvents tsa polar), le thepa e ntle ea ho pata motlakase.
● Li-o-ring tsa EPDM li ka 'na tsa boela tsa e-ba le phapang ea tšepe e bonahalang ha li ntse li boloka litšoaneleho tse tšoanang le tsa EPDM o-ring compound.EPDM o-rings ka tloaelo e ntšo ka 'mala, e na le nako e telele ea bophelo.Cure System: Peroxide-Cured Standard EPDM metsoako ea o-ring hangata e phekoloa ka sebabole.
● Metsoako e entsoeng ka sebabole e fana ka thepa e feto-fetohang hantle empa e atisa ho thatafala 'me e na le compression e tlaase e behiloeng ka mocheso o phahameng.Peroxide-cured EPDM o-ring compounds na le mocheso o matla o hanyetsanang le mocheso o tlaase oa compression.E lumellana le tšebeliso ea nako e telele, haholo-holo bakeng sa lisebelisoa tsa hose indastering ea kaho, empa e theko e boima haholo ebile e thata ho feta tlhahiso ea DMEP e entsoeng ka sulfur.
