ためほとんど溶融流動しないためと考えられる。In the above-mentioned prior art, in order to miniaturize the resin content of the heat insulating material, after compressing with a piston into briquettes, this briquette is miniaturized again with a screw conveyor. As a result of experiments conducted by the inventors regarding miniaturization, it was found that the heat insulating material was partially melted and solidified due to frictional heat in the screw, and stable miniaturization was difficult. It is considered that this is because the foamed polyurethane hardly melts and flows because it is a thermosetting resin.
