三元乙丙橡膠的分子量及分布可以通過凝膠滲透色譜法使用二氯苯作為溶劑在高溫下（150℃）測量而得。分子量分布通常被稱為是重量平均分子量與數(shù)量平均分子量的比例。根據(jù)普通和高度支化的結(jié)構(gòu)，這個值通常在2到5之間變化。三元乙丙橡膠的門尼粘度可以反映其分子量的大小，三元乙丙橡膠的門尼粘度范圍通常在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，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）。但是過高的分子量也會使得橡膠的流動性能變差，這意味橡膠后續(xù)加工會更加的困難，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，加工性能優(yōu)異三元乙丙膠錦湖服務(wù)為先，正面的影響有：增加的混煉和碾磨加工性。但是，加工性能優(yōu)異三元乙丙膠錦湖服務(wù)為先，加工性能優(yōu)異三元乙丙膠錦湖服務(wù)為先，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。比較簡單有效地提高粘合力的辦法是提高溫度和壓力。加工性能優(yōu)異三元乙丙膠錦湖服務(wù)為先</p><div

納米材料增強(qiáng)：用納米技術(shù)能夠在分子水平上重組物質(zhì)結(jié)構(gòu)，從而使新材料具有比傳統(tǒng)材料更優(yōu)越的性能。通過填充納米填料制備橡膠納米復(fù)合材料（分散相至少有一維的尺寸介于１~１００nｍ）已成為目前研究的新熱點。由于納米粒子具有的小尺寸效應(yīng)、量子效應(yīng)、不飽和價效應(yīng)和電子隧道效應(yīng)等表面效應(yīng)，因此引入納米填料將使橡膠的性質(zhì)發(fā)生很大改變，并有可能獲得一些新的性能。 </p> <p> 納米材料增強(qiáng)ＥＰＤＭ研究近年十分活躍，主要有納米粘土（層狀硅酸鹽）、納米二氧化硅、納米碳酸鈣、炭黑一白炭黑雙相納米填料、納米氧化鋅、納米氫氧化鎂、納米石墨、納米氧化鋁、納米氮化硅、納米丙烯酸金屬鹽、納米ＰＴＥＥ、碳納米管和納米級纖維等，使ＥＰＤＭ獲得更優(yōu)異、更***的性能，進(jìn)一步拓寬ＥＰＤＭ使用范圍。 </p><p> EPDM共混改性二： </p> <p> ＥＰＤＭ／聚酰胺（ＰＡ）：ＰＡ具有很高的抗張強(qiáng)度和抗沖擊韌性和耐磨性，與ＥＰＤＭ共混為一種高彈性模量和良好加工性能的彈性體，主要用于制造汽車零部件和建筑材料。北京化工大學(xué)馬勇等選用氯化聚乙烯（ＣＰＥ）作為ＥＰＤ脅體系的增容劑，研究得至ＵＣＰＥ的比較好用量是ＰＡ的１／２，當(dāng)ＰＡ用量為３０-４０份時產(chǎn)生比較好增***果。該項研究產(chǎn)物**提高了ＥＰＤＭ撕裂強(qiáng)度，而磨耗降低和耐油性提高，尤其是通過壓延拉伸ＰＡ能形成類似短纖維補(bǔ)強(qiáng)的微纖復(fù)合材料（ⅧＲＣ）。 </p> <p> ＥＰＤＭ／有機(jī)硅硅橡膠（ｖＭＱ）ＥＰＤＭ與有機(jī)硅橡膠改性，可以獲得許多優(yōu)異特性，在耐熱性、耐候性、壓縮長久變形性能方面優(yōu)于硅橡膠，既可用硫磺硫化，又可用過氧化物硫化，適用于多種成型方式，因此可用于硅橡膠或乙丙橡膠不能適應(yīng)的場合，如汽車減震材料、發(fā)動機(jī)耐熱部件、電氣部件等，耐熱等級從ＥＰＤＭ的１５０℃提高到１７５℃。 </p> <p> <br /> EPDM與硅橡膠有一定的相容性，用EPDM改性后的硅橡膠性能明顯提高可應(yīng)用于許多領(lǐng)域。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
