Three different experimental techniques [compression experiments at low strain rates, instrumented falling‐weight impact tests, and dynamic mechanical analysis (DMA)] have been used for the mechanical characterization of a collection of crosslinked closed‐cell polyolefin foams of different chemical compositions, densities, and type of cellular structure. The experimental results that it is possible to obtain from each technique are shown, and related to the different applications of these materials. The relationships between the structure and the mechanical properties are also presented. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 75: 156–166, 2000
