摘要:
It is an object of the present invention to provide a pressure-sensitive adhesive sheet for covering in which tensile strength is relatively low, tensile elongation is relatively large, slippage and deterioration due to high temperature can be suppressed, and excellent adhesiveness is exhibited. A pressure-sensitive adhesive sheet for covering according to an embodiment of the present invention includes a non-crosslinked rubber component having a maximum peak of the molecular weight distribution in the range of 50,000 to 3,000,000, an oil component having a maximum peak of the molecular weight distribution in the range of 1,000 to 20,000, and carbon black. The content of the non-crosslinked rubber component is 25% to 65% by mass, the content of the oil component is 35% to 75% by mass, and the content of the carbon black relative to 100 parts by mass of the total of the non-crosslinked rubber component and the oil component is 1 to 40 parts by mass. The pressure-sensitive adhesive sheet for covering may further include an inorganic filler other than the carbon black, and the content of the inorganic filler relative to 100 parts by mass of the total of the non-crosslinked rubber component and the oil component is preferably more than 0 parts by mass and 200 parts by mass or less.
