三元乙丙膠性能特點(diǎn)：與其他常用的通用橡膠或特種橡膠相比，三元乙丙橡膠的主要性能優(yōu)勢在于以下幾方面：(1)性價比高，生膠密度只有～，是生膠密度**輕的常用橡膠；且可大量填充以降低膠料成本。(2)優(yōu)異的耐老化特性，耐天候、耐臭氧、耐日光、耐熱、耐水、耐水蒸氣、耐紫外線、耐輻射等老化性能，在與其他不飽和的二烯類橡膠如NR、SBR、BR、NBR、和CR等并用時，EPDM可起到高分子抗氧劑或防老劑的作用。(3)優(yōu)異的耐化學(xué)藥品特性，耐酸、堿、洗滌劑、動植物油、醇、酮等；杰出的耐水、耐過熱水、耐水蒸氣性能；耐極性油性能。(4)優(yōu)良的絕緣性能，體積電阻率1016Q·cm、擊穿電壓30～40MV/m、介電常數(shù)(1kHz，20℃)。(5)適用溫度范圍廣，比較低使用溫度-40～-60℃，可長期在130℃條件下使用。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。KEP-270錦湖誠信經(jīng)營</p><p style="text-indent:25px">三元乙丙橡膠塑煉效果差，缺乏粘著性，不易“吃”炭黑，不宜包輥。KEP-270錦湖誠信經(jīng)營</p><p style="text-indent:25px">接枝改性是改善乙丙橡膠性能缺點(diǎn)的重要途徑之一，也為制備綜合性能更優(yōu)異的改性乙丙橡膠提供了可能。乙丙橡膠的接枝改性就是通過在其分子主鏈上接枝含有特征官能團(tuán)的極性支鏈單體，提高聚烯烴基體與其它極性成分界面的結(jié)合力，使其它極性材料得以均勻分散，提高材料的物理性能及產(chǎn)品的性能穩(wěn)定性，從而改善乙丙橡膠的自粘性、互粘性以及相容性。接枝改性乙丙橡膠主要用于改善乙丙橡膠與其它材料的結(jié)合強(qiáng)度、相容性、填料界面的結(jié)合、制品韌性、沖擊強(qiáng)度、低溫脆性及耐熱性等。乙丙橡膠接枝改性技術(shù)主要包括溶液接枝法、熔融接枝法等，近年來又發(fā)現(xiàn)了電子束輻射接枝和直接溶脹接枝等新的接枝方法，為乙丙橡膠接枝改性提供了更***的技術(shù)可行性。KEP-270錦湖誠信經(jīng)營</p><p
