摘要: The present invention relates to a method for preparing foamed item, including the following steps: a) heating composition including, or consisting of, at least one polyamide PA, compound U urethane function, particularly polyurethane PU, reinforcing filler, content of which is no lower than 10 wt% total weight composition, and temperature T such that: directly indirectly generates CO 2 , melted, in particular, that injectable; b) injecting extruding said injection being molding; c) recovering item an expandable granule polyamide, U, filler composition. also use granule, foam item.
