1. Babban juriya ga tsufa
Kyakkyawan juriya na lemar sararin samaniya - EPDM an san shi da "roba mara fashewa", kuma yana da mafi kyawun juriyar lemar sararin samaniya tsakanin robar manufa ta gaba ɗaya.
B Kyakkyawan kwanciyar hankali na thermal.
C Excellent tsufa juriya - za a iya amfani da dogon lokaci a 130 ℃, kuma za a iya amfani da intermittently ko gajere a 150 ℃ ko mafi girma zafin jiki.
D Kyakkyawan juriya na yanayi - yana nufin tsufa na abubuwan haɗin gwiwa na haske, zafi, daskarewa, iska, ruwan sama, ozone da oxygen a cikin yanayin yanayi.
2. Kyakkyawan juriya na sinadarai: Saboda daidaiton sinadarai da rashin polarity na EPDM kanta, ba ya amsa sinadarai tare da yawancin sinadarai, kuma bai dace ba ko yana da ɗan daidaitawa da abubuwan polar.Yana da tsayayya ga barasa, acid (formic acid, acetic acid), tushe mai karfi, oxidants (irin su H2O2, HCLO, da dai sauransu), kayan wankewa, dabba da kayan lambu mai, ketones, wasu fats, da hydrazine.
3. Kyakkyawan juriya na ruwa, juriya mai zafi da juriya na ruwa: ruwa abu ne mai karfi na polar, kuma EPDM roba wani nau'i ne na macromolecular alkanehydrazine tare da "hydrophobicity".Babu wata hulɗar sinadarai tsakanin su biyun, don haka yana da kyakkyawan juriya na ruwa, juriya mai zafi da juriyar tururin ruwa.
EPDM kayan kaddarorin
Siffofin samfur na EPDM roba kumfa soso: An raba samfurin zuwa rufaffiyar tantanin halitta da buɗaɗɗen tantanin halitta.Tantanin halitta na ciki na kayan kumfa mai rufaffiyar an raba shi daga tantanin halitta ta hanyar fim ɗin bango, wanda ba a haɗa shi da juna ba.Siffar tantanin halitta ce mai zaman kanta, kuma babba Ƙaramar tantanin halitta ce mai kama da tantanin halitta ko matuƙar ƙanƙanta;sel na ciki na buɗaɗɗen buɗaɗɗen kayan kumfa suna haɗuwa da juna, kuma suna da alaƙa da fata ta waje, wanda shine tsarin tantanin halitta mara zaman kanta, galibi mafi girma sel ko ramuka mara kyau.
