Polymeric materials are used for vibration protection owing to their high-energy dissipation or adsorption. In this study, polyurethane elastomers (PUEs) were prepared using six kinds of chain extender and three types of cross-linking agent. The relationships between their structures and vibration isolation performances were investigated in detail using an independent building vibration isolation sensor. The results showed that elastomers with fewer main chain carbon atoms exhibited better vibration isolation performance. With increasing number of side groups of the chain extender, both the damping and vibration isolation properties were improved. For different cross-linkers, a more irregular structure of the cross-linkers resulted in the better vibration isolation performance of the PUEs.
