PROBLEM TO BE SOLVED: To provide a heat-resistant cushioning material suitable for the cushioning material or the like of a vacuum hot press, and a method for manufacturing the same. SOLUTION: The heat-resistant cushioning material consists of a heat-resistant cushioning layer and the heat-resistant films applied to both surfaces of the cushioning layer, and is constituted by mutually laminating the heat-resistant films along the outside periphery of the heat-resistant cushioning layer under heating and vacuum as they are or through a heat-resistant adhesive film to hermetically seal the heat-resistant cushioning layer. This heat-resistant cushioning material can be repeatedly used at 250 deg.C or higher under vacuum and generates no dust substantially. The method for manufacturing the heat- resistant cushioning material by vacuum press molding is also disclosed. Accordingly, the heat-resistant cushioning material having cushioning properties at a high temperature up to 400 deg.C, generating no dust, having uniformity and usable repeatedly under vacuum is obtained. |
