悪い。The flexible polyurethane foam of the present invention is useful as a thermoforming material, and thermoforming is carried out by heating and pressing with a conventional device. The heating may be performed by a microwave other than the usual method. For thermoforming, the foam may be heated to a predetermined temperature immediately before pressing and pressed with a press machine at room temperature or cooled, but it is preferable to use a hot press machine capable of heating the pressing surface and press while heating. The heating temperature is usually 100 to 210 ° C., preferably 15
It is 0 to 200 ° C. If the heating temperature is less than 100 ° C, the thermoformability is poor, and if it exceeds 200 ° C, the foam is discolored and deteriorated by heat. Pressurization is usually performed at 0.5 Kg / cm 2 or more. If the pressure is less than 0.5 Kg / cm 2 , the thermoformability is poor.
