Due to stepwise improvements in polymer processing and recent catalyst developments, new Ethylene-Propylene-Diene-Monomer (EPDM) polymers of very high molar mass have recently been synthesized. These terpolymers exhibit up to date unseen strong mechanical properties, especially at elevated temperatures. In the present study, we investigate the dynamic-mechanical properties of certain crosslinked polymer blends containing EPDM reinforced with carbon black with respect to a significant increase of crack growth resistance and the fatigue lifetime without deteriorating the excellent heat stability of EPDM-based elastomers. Applications such as engine mounts, vibration isolation applications, exhaust mounts, and suspension bushings can benefit from the advantage of the saturated polymer backbone of EPDM, the strength and resilience of high molar mass EPDM, and the compounding techniques shown in this paper.
