復する。それを緩衝材として使用すればよい。In order to compress the polystyrene, block-shaped or plate-shaped high-magnification expanded polystyrene is heated to a temperature lower than the softening temperature of polystyrene.
Preferably, it is compressed at a temperature around room temperature, if necessary, at a temperature below room temperature by a roll method or a press method or a combination thereof so that the thickness becomes 5 to 20% of the original thickness. Although the compression time is arbitrary, it is advantageous to shorten the compression time industrially. However, it is natural that the optimum condition can be determined in consideration of the degree of thickness recovery and the dynamic spring constant. When the compression load is removed, the thickness recovers to about 30 to 90%, preferably 40 to 80% of the original thickness. It may be used as a cushioning material.

In that case, it is only necessary to slice and use the required thickness. It can also be cut or cut into various shapes for use.
