摘要： Disclosed is a cushioning material for a polishing pad, which hardly suffers swelling deformation caused by water because it is extremely low in water-absorbing characteristics and water-swelling characteristics. The cushioning material for a polishing pad includes a polyurethane foam capable of polishing even a semiconductor wafer having an undulated surface or a wafer having a local step that is formed during circuit forming process so that the undulation or step becomes smaller by uniformly polishing an entire surface of the wafer along the undulation or step. The cushioning material for a polishing pad is characterized by including a polyurethane foam obtained by reacting polyol and polyisocyanate with each other, the polyurethane foam having a contact angle with water of 90° or more. The polyurethane foam is preferably made by using hydrophobic polyol, and preferably has a self-skin layer formed thereon.

摘要： To provide a cushioning material for flexographic printing in which an adhesive strength between the cushioning material and an adhesive increases when adhesion processing is performed on the cushioning material, and hence no adhesive remains on an adherend such as a printing cylinder when a printing plate is peeled off from the adherend. The cushioning material for flexographic printing includes a polyurethane foam produced by using a reactive silicone foam stabilizer. The reactive silicone foam stabilizer used for producing the polyurethane foam has an SiO % preferably in the range of 10 to 25%. The polyurethane foam has a density preferably in the range of 0.1 to 0.7 g/cm3 and a bubble fraction of 60% or less.

摘要： A flexographic printing plate mounting sheet is provided which improves the printing accuracy by its high level of thickness accuracy and ease of installation in the correct position, which makes it possible to peel a flexographic printing plate off without damaging a foamed substrate, and which maintains appropriate cushioning properties. The foamed substrate of the flexographic printing plate mounting sheet has an adhesive layer on one side and a polyethylene terephthalate film on the other side. The polyethylene terephthalate film has on its remaining side an adhesive layer that is protected by release paper. The foamed substrate and the polyethylene terephthalate film are unitarily formed. The foamed substrate is made of urethane foam having a density of 0.3 to 0.6 g/cm3. The polyethylene terephthalate film is 12 to 50 μm in thickness.
