Rubbers are used in many applications in industries such as chemistry, automotive, agriculture, and aviation. However, different types of rubbers should be used to meet the end-user expectations in all these areas of use. In recent years, the use of the blending method has obtained both superior properties and low-cost rubbers with the synergistic effect of two different rubbers. Ethylene acrylic rubber (AEM) is resistant to heat, chemicals, and ozone, but it is not well resistant to low aniline oil and polar solvents. In addition, AEMs are much more expensive than most standard elastomers. In this study, the upside-down method was applied to preparing the series of AEM and Ethylene propylene diene monomer (EPDM) rubber blends in a Banbury-type internal mixer. Rubber blends were a mixture of AEM and EPDM rubber in 90/10, 20/80, 30/70, and 60/40 phr rubber ratio variation. In addition, each of the blends was tested to determine rheological and mechanical properties such as tensile strength, elongation at break, hardness and compression set as well as thermal and oil (IRM 901 and IRM 903) aging effects. The 10% addition of EPDM rubber causes an increment in the compression set, the tensile strength, and elongation at break. It was observed that the tensile strength values of A100 and A90E10 samples were larger than 8 MPa and the hardness value did not change after aging in IRM 901 oil. A100 and A90E10 samples show satisfying results to the requirements SAEJ200M3EE708 standard.

橡胶广泛用于化学，汽车，农业和航空等行业。但是，在所有这些使用领域中，应使用不同类型的橡胶以满足最终用户的期望。近年来，使用共混方法已经获得了优异的性能和低成本的橡胶，并具有两种不同橡胶的协同作用。乙烯丙烯酸橡胶（AEM）耐高温，耐化学药品和耐臭氧性，但对低苯胺油和极性溶剂的耐性不是很好。此外，AEM比大多数标准弹性体贵得多。在这项研究中，采用倒置法在班伯里式混合器中制备一系列AEM和乙烯丙烯二烯单体（EPDM）橡胶共混物。橡胶混合物是AEM和EPDM橡胶在90 / 10、20 / 80、30 / 70，和60/40 phr橡胶比例变化。此外，还对每种共混物进行了测试，以确定其流变和机械性能，例如拉伸强度，断裂伸长率，硬度和压缩永久变形以及热和油（IRM 901和IRM 903）的老化效果。EPDM橡胶的10％添加会导致压缩永久变形，拉伸强度和断裂伸长率增加。可以看出，在IRM 901油中老化后，A100和A90E10样品的拉伸强度值大于8 MPa，硬度值没有变化。A100和A90E10样品显示出符合SAEJ200M3EE708标准要求的令人满意的结果。硬度和压缩永久变形以及热和油（IRM 901和IRM 903）的老化效果。EPDM橡胶的10％添加会导致压缩永久变形，拉伸强度和断裂伸长率增加。可以看出，在IRM 901油中老化后，A100和A90E10样品的拉伸强度值大于8 MPa，硬度值没有变化。A100和A90E10样品显示出符合SAEJ200M3EE708标准要求的令人满意的结果。硬度和压缩永久变形以及热和油（IRM 901和IRM 903）的老化效果。添加10％的EPDM橡胶会导致压缩永久变形，拉伸强度和断裂伸长率增加。可以看出，在IRM 901油中老化后，A100和A90E10样品的拉伸强度值大于8 MPa，硬度值没有变化。A100和A90E10样品显示出符合SAEJ200M3EE708标准要求的令人满意的结果。
