DE304: A New EPDM Grade for Elevated Temperature Dynamic Applications

There are increasing demands on the performance of many elastomeric components used in the automotive industry. These arise from the requirements of longer component lifetime, enhanced levels of performance, and increasing continuous operating temperatures in the engine compartment. The engine mount is a critical application where these trends have created major difficulties for the materials engineer. Natural rubber, historically the elastomer of choice, may be unsurpassed in dynamic properties, strength, and fatigue resistance but it is approaching the endurance limit with regard to higher continuous operating temperatures. Of the possible replacement elastomers, EPDM, with an appropriately designed molecular structure, is the best solution. After heat ageing at 120
