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(shì)在于以下幾方面 [2] ： (1)高，生膠密度只有0.86～0.90g/cm3，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(shí)，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(dòng)植物油、醇、酮等；杰出的耐水、耐過熱水、耐水蒸氣性能；耐性油性能。 (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℃)2.27。 (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。
