The Effect of Chemical Composition, Density and Cellular Structure on the Dynamic Mechanical Response of Polyolefin Foams

Dynamic mechanical analysis has been applied to a collection of polyolefin foams with different chemical compositions and densities and manufactured from different routes. The effect of different foam characteristics, such as density, polymer morphology and cellular structure on the dynamic mechanical response is analysed. The way in which this technique can be used to obtain information about the polymer morphology of the foam is presented. In addition, examples of the use of this technique in studying specific problems are illustrated.
