Abstract

The present invention concerns layered foamed polymeric materials lacking discontinuities at the interface between the layers and a preparation process thereof comprising the following steps: —providing a foamable polymeric material; —solubilising said one or more foaming agents in the foamable polymeric material under pressure and at a temperature greater than 20° C.; and —releasing the pressure instantaneously; where the solubilisation step is carried out with a pressure profile of said one or more foaming agents that is variable over time.
