樹脂。For polyurethane foam, it is thought that a foam structure with open cells is preferable, and if possible, it is ideal for the foam cells to have a non-uniform and complex shape rather than a uniform shape. Polyurethane foam itself does not have the ability to self-retain its shape, so thermosetting resins such as epoxy, polyester, and melamine are used.

形状の現出が不充分であった。Methods of applying resin processing with incyanates, or laminating various nonwoven fabrics, glass papers, and various film sheets on the front and back surfaces of the foam, either alone or impregnated with resin, to create a sandwich structure are adopted. In both cases, open polyurethane foam was used as the core material, so the shape retention was slightly poor and when forming a shape with deep drawability, the shape was insufficiently expressed.
