PROBLEM TO BE SOLVED: To provide a shape-following resin foam, a method of its use and a cushioning material mounted for human body. SOLUTION: The shape-following resin foam (soft polyurethane foam and the like) is characterized in that the glass transition temperature, denoted as a temperature corresponding to the peak value of a loss tangent, is 10-35°C, the loss tangent in this temperature range is 0.20-0.80, and the ratio (G'max/G'min) of the maximum value (G'max) to the minimum value (G'min) of the storage modulus (G') in this temperature range is 3.0-30. The method of its use is that a molding formed by using the shape-following resin foam is mounted on the body surface of a human body; then the hardness of the molding is let to be lowered by the heat transfer from the human body; and the molding is allowed to follow the shape of the body surface and to accordingly deform for its use. The cushioning material mounted for human body is formed of the molding obtained by using the shape-following resin foam. COPYRIGHT: (C)2009,JPO&INPIT |
