ABSTRACT:
Motor vehicle vibration damping parts based on an ethylene, alpha-olefin, vinyl norbornene elastomeric polymer are manufactured with more efficiency due to vibration damping part compounds having lower viscosity, easier processing than ethylene, alpha-olefins, diene monomer compounds, where the diene monomer is other than vinyl norbornene. Additionally, the engine mounts or other vibration damping parts based on the ethylene, alpha-olefin, vinyl norbornene elastomeric polymer have better heat aging characteristics than natural rubber, when temperature of service exceed 120.degree. C., maintain more constant dynamic characteristics of the mount when running at elevated temperature like 120.degree. C. Finally the engine mounts or other vibration damping parts based on the ethylene, alpha-olefin, vinyl norbornene elastomeric polymer can be manufactured with compound containing less peroxide as curing agent, than ethylene, alpha-olefins, diene monomer compounds, where the diene monomer is other than vinyl norbornene. Those engine mounts or other vibration damping parts based on the ethylene, alpha-olefin, vinyl norbornene elastomeric polymer provide better aging properties so the service life of the parts are greatly extended vs. natural rubber part.
