An engine mount secures the engine of a vehicle to its chassis. Successful application of elastomeric mounts as vehicle engine mounts has been observed over the years. Epoxidised Natural Rubber (ENR) and Deproteinised Natural Rubber (DPNR) are specialty rubbers with a potential for application in the development of engine mounts. In this study, a blend comprising natural rubber (NR) and polybutadiene rubber (BR) is used to produce the Original Equipment Manufacturer (OEM) part. Epoxidised Natural Rubber (ENR25 and ENR50) and Deproteinised Natural Rubber (DPNR) developed by Malaysian Rubber Board were used and compared with NR by evaluating both physical and mechanical properties of the rubbers with different filler loadings. The physical properties of NR exhibited excellent results opposed to other rubbers. However, a blend of ENR25 and BR reflected good compression set at 100 ° C for 96 hours. The performance of an engine mount comprising a blend of ENR50 and BR is promising in reference to the excellent mechanical properties over that of other rubbers. Dynamic stiffness and damping characteristics of the engine mount play an important role to achieve vibration isolation with acceptable engine motion control in a vehicle’s engine mount system. It is perceived that engine mounts produced with a blend of ENR50 and BR can improve vibration effects in dynamic conditions.
