POLYPROPYLENE RESIN FOAMED SHEET, METHOD FOR PRODUCING POLYPROPYLENE RESIN FOAMED SHEET, AND ADHESIVE SHEET

摘要

Provided is a polypropylene resin foamed sheet with which it is possible to prevent water, dust, and the like from penetrating electrical and electronic equipment irrespective of the thickness of the polypropylene resin foamed sheet. The polypropylene resin foamed sheet of the present invention is a sheet-shaped foam of a resin composition including polypropylene resin and at least one among olefinic thermoplastic elastomers and polyethylenic plastomers. This resin composition constitutes the material of all of the thickness-direction center, a first surface on one thickness-direction side, and a second surface on the other thickness-direction side. The polypropylene resin foamed sheet has a thickness of 0.05-0.5 mm, a tensile strength of 0.1-30 MPa, and a 25% compressive stress of 10-150 kPa.
