Abstract

The present invention relates to a method for preparing a foamed item including the following steps: a) heating a composition including or consisting of at least one polyamide PA at least one compound U including at least one urethane function particularly a polyurethane PU at least one reinforcing filler the content of which is no lower than 10 wt% of the total weight of the composition and a temperature T such that: the compound U directly or indirectly generates CO the polyamide is melted and in particular such that the composition is injectable; b) injecting or extruding said composition the injection particularly being injection molding; and c) recovering the foamed item and an expandable granule including or consisting of at least one polyamide at least one compound U particularly a polyurethane PU and at least one reinforcing filler the content of reinforcing filler being no lower than 10 wt% of the total weight of the composition. The invention also relates to the use of such a composition of such a granule or a foam or foamed item.
