Polymer materials are widely used in vibration damping and buffering, and different materials and processing techniques would affect their buffering performance. In this study, the buffering performance of four kinds of specimens made of non-foamed polyurethane, foamed polyurethane, silicone rubber and PVC paste resin were examined by drop-weight tests. According to the drop-weight experimental principle and corresponding numerical simulation, the peak acceleration of the falling hammer could be used as the key index of buffering performance. The results show that the buffering performance of the non-foamed polyurethane and silicone rubber samples are relatively worse, while the foaming polyurethane and PVC paste resin samples have similar buffering performance.
