2)EPDM建(jian)筑(zhu)行業

由(you)于(yu)乙丙橡膠(jiao)(jiao)(jiao)具有(you)優(you)良的耐(nai)水性、耐(nai)熱耐(nai)寒性和耐(nai)候性，又(you)有(you)施工簡(jian)便等(deng)(deng)特點，因此乙丙橡膠(jiao)(jiao)(jiao)在建筑(zhu)行(xing)業(ye)中(zhong)主要用于(yu)塑膠(jiao)(jiao)(jiao)運(yun)動場(chang)、防(fang)(fang)水卷(juan)材(cai)、房(fang)屋門(men)窗密封(feng)(feng)條(tiao)、玻璃(li)幕墻密封(feng)(feng)、衛生設備和管道密封(feng)(feng)件等(deng)(deng)。乙丙橡膠(jiao)(jiao)(jiao)在建筑(zhu)行(xing)業(ye)中(zhong)用量(liang)(liang)最大(da)的還數塑膠(jiao)(jiao)(jiao)運(yun)動場(chang)和防(fang)(fang)水卷(juan)材(cai)，就國內用量(liang)(liang)而(er)言已占乙丙橡膠(jiao)(jiao)(jiao)總用量(liang)(liang)的26%-28%。用EPDM生產的防(fang)(fang)水卷(juan)材(cai)已逐漸(jian)代替其(qi)他材(cai)料(如(ru)CMS)制(zhi)作的防(fang)(fang)水卷(juan)材(cai)，尤其(qi)是用于(yu)地(di)下建筑(zhu)的防(fang)(fang)水卷(juan)材(cai)。

3)EPDM電氣(qi)和電子行業

在(zai)(zai)電(dian)(dian)(dian)氣(qi)和電(dian)(dian)(dian)子行(xing)業中(zhong)主要(yao)利用乙丙橡(xiang)(xiang)膠的(de)優良電(dian)(dian)(dian)絕緣(yuan)(yuan)性、耐候性和耐腐(fu)蝕性，在(zai)(zai)許多電(dian)(dian)(dian)氣(qi)部件中(zhong)采用了(le)(le)此類橡(xiang)(xiang)膠。例如用乙丙橡(xiang)(xiang)膠生產電(dian)(dian)(dian)纜(lan)(lan)，尤其(qi)是海(hai)底電(dian)(dian)(dian)纜(lan)(lan)用EPDM或EPDM/PP代(dai)替了(le)(le)PVC/NBR制(zhi)作電(dian)(dian)(dian)纜(lan)(lan)的(de)絕緣(yuan)(yuan)層(ceng)，電(dian)(dian)(dian)纜(lan)(lan)的(de)絕緣(yuan)(yuan)性能和使(shi)用壽命有了(le)(le)大幅(fu)度提高。在(zai)(zai)變(bian)壓器(qi)絕緣(yuan)(yuan)墊(dian)、電(dian)(dian)(dian)子絕緣(yuan)(yuan)護套方面也大量采用了(le)(le)乙丙橡(xiang)(xiang)膠制(zhi)作。
