Loj: Standard thiab Customized

Khoom siv: Nitrile / NBR / Buna, FKM / FPM, Silicone, EPDM, HNBR, NR, thiab lwm yam.

EPDM roj hmab gaskets muaj cua sov, huab cua tsis kam thiab ozone kuj vim hais tias lawv yog polymerized los ntawm propylene thiab ethylene. Ntawm qhov ozone concentration ntawm 100 * 10-8 (pphm), tsis muaj kev tawg tom qab 2430 teev, thiab sab nraum zoov lifespan tuaj yeem ncav cuag 25 xyoo. Nyob rau hauv cov dej vapor ntawm 160 degree, Ethylene propylene roj hmab kuj qhia tau hais tias kev ua tau zoo tshaj lwm yam roj hmab. Nws kuj muaj qhov zoo resilience, rwb thaiv tsev thiab kub tsis kam.

EPDM muaj feem xyuam rau ethylene glycol raws li tus brake kua, dej kub thiab chav, roj silicone thiab roj, tsiaj thiab zaub roj, feem ntau cov organic los yog Mineral acid, detergents, soaps thiab alkaline ib puag ncig uas muaj poov tshuaj ntawm 150 degree, feem ntau polar solvents (ketones, cawv. ), phosphate ester hydraulic roj, thiab tub yees R134a ntxiv rau PAG system. Nws muaj kev tiv thaiv zoo rau cov dej chlorine thiab ammonia, thiab tseem tuaj yeem siv rau hauv thaj chaw acetic acid hauv qab 3 feem pua ​​-5 feem pua, Tab sis nws tsis haum rau cov roj ntxhia thiab cov rog, nrog rau cov tshuaj tsw qab thiab cov kuab tshuaj olefinic.
