The smashed foam itself is the leftover of various foam materials (usually from PU foam (blue)), which is smashed then molded by hot gluing and pressing. It has absorbed the glue and been pressed into shape. A cross-linking agent is usually added during the foaming process, and the polymer is difficult to be thermoplastics again after being cross-linked. Thus the re-glued smashed foam has exerted its maximum utilization, and can hardly be reprocessed. So this material is usually designed to a life longer product, such as car foot pads, sofas inner support layers and others.more
