三元乙丙橡膠的分子量及分布可以通過(guò)凝膠滲透色譜法使用二氯苯作為溶劑在高溫下（150℃）測(cè)量而得。分子量分布通常被稱(chēng)為是重量平均分子量與數(shù)量平均分子量的比例，錦湖EPDM KEP-240。根據(jù)普通和高度支化的結(jié)構(gòu)，這個(gè)值通常在2到5之間變化。三元乙丙橡膠的門(mén)尼粘度可以反映其分子量的大小，三元乙丙橡膠的門(mén)尼粘度范圍通常在20到100之間。 </p> <p> 增加三元乙丙橡膠的分子量，正面影響有：更高的拉伸和撕裂強(qiáng)度，錦湖EPDM KEP-240，在高溫情況下更高的生坯強(qiáng)度，能夠吸收更多的油和填料（低成本）。但是過(guò)高的分子量也會(huì)使得橡膠的流動(dòng)性能變差，錦湖EPDM KEP-240，這意味橡膠后續(xù)加工會(huì)更加的困難，比如更難混煉，更難充模，更難擠出等等，隨著分子量分布的增加，正面的影響有：增加的混煉和碾磨加工性。但是，較窄的分子量分布可以改進(jìn)硫化速度，硫化狀態(tài)以及注塑行為。 EPDM用于制作發(fā)動(dòng)機(jī)冷卻系統(tǒng)中的密封圈。錦湖EPDM KEP-240</p><div

據(jù)MarketsandMarkets報(bào)道預(yù)計(jì)，2020年全球三元乙丙橡膠(EPDM)市場(chǎng)規(guī)模達(dá)72億美元，在2015-2020年之間以5．4％的復(fù)合年增長(zhǎng)率增長(zhǎng)。EPDM主要用于汽車(chē)、建筑與施工、輪胎與管、電線(xiàn)與電纜和潤(rùn)滑添加劑。該需求將不斷地受到增長(zhǎng)的終端用戶(hù)產(chǎn)業(yè)、彈性體的需求增加、發(fā)展策略提升及擴(kuò)張和收購(gòu)活動(dòng)增加的推動(dòng)。估計(jì)潤(rùn)滑添加劑是增長(zhǎng)**快的應(yīng)用。EPDM還可被用作潤(rùn)滑劑中的黏度改進(jìn)劑(Ⅵ)。汽車(chē)產(chǎn)業(yè)是全球EPDM市場(chǎng)中比較大的終端用途產(chǎn)業(yè)細(xì)分市場(chǎng)。全球EPDM在汽車(chē)產(chǎn)業(yè)中的消費(fèi)主要是由于其高耐熱性和耐氣候性及振動(dòng)吸收性能。由于這些性能，EPDM還用于軟管、引擎蓋下的機(jī)械產(chǎn)品、車(chē)身密封膠、擋風(fēng)雨條、傳送帶、引擎支架、剎車(chē)配件、雨刮器等。在汽車(chē)產(chǎn)業(yè)中EPDM市場(chǎng)也受到了新興經(jīng)濟(jì)體生活標(biāo)準(zhǔn)提高的推動(dòng)。據(jù)報(bào)道，亞太地區(qū)是比較大的EPDM市場(chǎng)，包括中國(guó)、日本、馬來(lái)西亞、印度、中國(guó)臺(tái)灣和韓國(guó)。2014年亞太地區(qū)市場(chǎng)大約占全球EPDM市場(chǎng)的40％，且在2020年之前預(yù)計(jì)這個(gè)地區(qū)仍將主導(dǎo)市場(chǎng)。預(yù)計(jì)在2020年之前亞太地區(qū)還將是比較大的區(qū)域市場(chǎng)，以高投資于汽車(chē)、塑料改性和建筑行業(yè)等應(yīng)用。并且預(yù)計(jì)亞太地區(qū)將是增長(zhǎng)**快的EPDM市場(chǎng)。這種高增長(zhǎng)歸因于不斷增長(zhǎng)的汽車(chē)市場(chǎng)和中國(guó)國(guó)內(nèi)需求增加

ＥＰＤＭ／乙烯．醋酸乙烯共聚物（EVM）：通過(guò)與不同ＶＡ含量的ＥＶＭ橡膠的并用，以及采用不同的共混比，研究了ＥＰＤＭ與ＥＶＭ并用膠料對(duì)物理機(jī)械性能的影響。結(jié)果表明：ＥＰＤＭ與ＥＶＭ并用，可以有效改善ＥＰＤＭ膠料的耐熱性、耐油性、耐低溫性、耐溶劑性及阻燃性，粘合性能增加。同時(shí)降低了膠料的門(mén)尼粘度，并用膠具有良好的混煉工藝及成型加工性。

ＥＰＤＭ的硫化速度較慢，耐油性及粘合性較差，若使其與橡膠如天然橡膠（ＮＲ）、丁腈橡膠（ＮＢＲ）、丁基橡膠（ＩＩＲ）、甲基乙烯基硅橡膠（ＶＭＱ）、氯磺化聚乙烯（ＣＳＭ）、氯丁橡膠（ｃＲ）、氯化聚乙烯（ＣＰＥ）等并用改性，可以很好地綜合不同種類(lèi)橡膠的優(yōu)異性能，改善各自的不足。一方面，ＥＰＤＭ可以改善其他膠種的耐熱性、耐低溫性、耐臭氧及耐水蒸氣性能等；另一方面，又會(huì)使ＥＰＤＭ本身的加工性、耐油性和粘合性得到提高。因此，ＥＰＤＭ與其他橡膠共混改性，可制造出許多具有優(yōu)異性能的新材料。ＥＰＤＭ具有飽和主鏈和低不飽和側(cè)鏈，與塑料和其他橡膠共混、動(dòng)態(tài)硫化改性，可制造多種性能優(yōu)異的新型材料。典型共混物是與聚丙烯（ＰＰ）共混動(dòng)態(tài)硫化改性制成全硫化ＴＰＶ。因此使用橡膠產(chǎn)品要求性能上年然而，在不能準(zhǔn)確把任何時(shí)候添加材料，都可能成為泄漏、起霜等負(fù)面因素。錦湖EPDM
