The invention provides an adsorption temporary fixing material, which can adhere to an adherend without entrapment and be temporarily fixed. It is difficult to peel off from a specified position under any of high temperature and low temperature, and no paste remains when the temporary fixing is released The agent is peeled off, and even if it is contaminated, it can be used repeatedly by washing to restore the adsorption. The adsorption temporary fixing material of the present invention is an adsorption temporary fixing sheet having a foam layer with a continuous bubble structure, and the foam layer is provided on the whole or at least one surface of the sheet when the stretching speed is 50 mm / min The shear adhesion of the surface of the foamed layer to the SUS304BA board at 23 ° C is 1 N / 100 mm 2 or more. When the peeling angle is 180 degrees and the stretching speed is 300 mm / min, the foamed layer The peeling force of the surface from the SUS304BA board at 23 ° C is 1 N / 20 mm or less. The weight change after wiping the water droplets on the surface after immersing the adsorption temporary fixing sheet in distilled water for 1 minute is 50% or less. |
