Ultra High Molecular Weight EPDM Vs. Natural Rubber for Dynamic Applications

Ultra-high Molecular Weight EPDM vs. Natural Rubber (NR) for Dynamic Applications

Compounds based on high molecular weight (MW) EPDM will be prepared in our lab and compared with NR for their processability and dynamic properties. Historically, NR has been the choice for molding engine mounts to isolate engine vibration for the cars. The engine mounts molded from NR are facing great challenges because the latest trend in the auto industry requires better heat aging and ozone resistance. EPDM would be a fit only if it gives comparable vibration isolation funder the car engines.

In this study, we will compare all the compounds regarding their curing profiles and physical properties. In addition, heat aging, low temperature, and anti-vibration characteristics will be evaluated.
