乙丙橡膠耐老化性好。它是乙烯和丙烯在催化劑作用下共聚而成。該品具有良好的化學(xué)穩(wěn)定性、耐熱性、耐酸、耐堿性、耐寒性。對(duì)于高壓蒸汽和磷酸脂系用乙丙膠制密封件可得到十分滿意的效果。在礦物油中不宜使用，因易泡漲。乙丙橡膠缺點(diǎn)是在室溫下粘度不好，給加工制造帶來(lái)困難。硫化時(shí)間也長(zhǎng)，為此人們研究了三元乙丙膠，即在橡膠分子側(cè)鏈中引進(jìn)不飽和鍵，所以可以用硫磺硫化，同時(shí)也便于加工，錦湖KUMHO接角用EPDM。乙丙橡膠綜合物理機(jī)械性能介于天然膠與丁苯膠之間，與丁基橡膠類似。使用溫度 -45~1 50℃。在一般的橡膠制品中，乙丙膠件使用壽命**長(zhǎng)。目前密封條市場(chǎng)主要以三元乙丙（ EPDM

8.PDM的成型方式壓出膠料壓出性能往往是以膠料容易輸送、壓出速度快、壓出物表面光滑以及形狀、尺寸保持性好為標(biāo)志。三元乙丙橡膠比一般橡膠容易壓出，壓出速度較快，壓出物收縮小，但要控制好膠料的門尼粘度和壓出溫度。乙丙橡膠膠料門尼粘度以40~60為佳。乙烯含量高及分子量分布窄的三元乙丙橡膠壓出工藝性能好。高填充配合的膠料亦有良好的壓出性能，特別是填充高結(jié)構(gòu)爐黑、快壓出爐黑、通用爐黑、半補(bǔ)強(qiáng)爐黑、中粒子熱裂法炭黑和細(xì)粒子熱裂法炭黑等炭黑的膠料壓出表面光滑。白色填料以鈦白、滑石粉、碳酸鈣為比較好，壓出速度超過(guò)炭黑膠料。壓延EPDM膠料需要通過(guò)壓延制備各種規(guī)格膠片以及在織物上擦膠或貼膠。膠料門尼粘度、壓延速度和溫度均會(huì)影響壓延物質(zhì)量。壓延溫度過(guò)低容易產(chǎn)生氣泡，壓延物不平整，收縮大。一般壓延溫度應(yīng)控制如下：上輥90~100℃，中輥90℃左右，下輥90~120℃。模壓三元乙丙橡膠高溫流動(dòng)性較好，故制造模壓制品時(shí)沒(méi)有什么困難。但制造結(jié)構(gòu)復(fù)雜的模制品時(shí)，要在模型關(guān)鍵部位鉆些氣眼以排出窩藏的氣體，避免制品產(chǎn)生氣孔缺點(diǎn)或表面發(fā)粘等。用過(guò)氧化物硫化的膠料熱撕裂性能差，配方中應(yīng)采用少量硫磺作共交聯(lián)劑以改善其熱撕裂性能。
