Abstract: The present invention relates to a double-sided pressure-sensitive adhesive tape excellent in good balance of both flame retardance and pressure-sensitive adhesive properties, comprising a layer structure of a pressure-sensitive adhesive layer (I), a substrate, and a pressure-sensitive adhesive layer (II) in this order, in which a proportion (Y/X) of a thickness (X) of the pressure-sensitive adhesive layer (I) and a thickness (Y) of the pressure-sensitive adhesive layer (II) is more than 1.00 and less than 2.00.

Abstract: The present invention relates to a double-sided pressure-sensitive adhesive tape comprising a layer structure of a pressure-sensitive adhesive layer (IA), a substrate, and a pressure-sensitive adhesive layer (IIA) in this order, wherein a flame retardant (C) is contained in at least one of the pressure-sensitive adhesive layer (IA) and the pressure-sensitive adhesive layer (IIA), a content of the flame retardant (C) is 10 parts by mass or less with respect to 100 parts by mass of a total amount of the resin components in the pressure-sensitive adhesive layer (IA) and the pressure-sensitive adhesive layer (IIA), and a proportion (YA/XA) of a thickness (XA) of the pressure-sensitive adhesive layer (IA) and a thickness (YA) of the pressure-sensitive adhesive layer (IIA) is 2.00 or more.

Abstract: To provide a double-sided pressure-sensitive adhesive tape for fixing aircraft parts which is excellent in terms of hand tearability, flame retardance, and removability in a well-balanced manner. A double-sided pressure-sensitive adhesive tape for fixing aircraft parts which is a double-sided pressure-sensitive adhesive tape having pressure-sensitive adhesive layers on both sides of a substrate having hand tearability, characterized in that when S represents an pressure-sensitive adhesive strength of one pressure-sensitive adhesive layer (I) and W represents an pressure-sensitive adhesive strength of the other pressure-sensitive adhesive layer (II), the W is 2-20 N/25 mm and S/W is 1.5 or larger, and the double-sided pressure-sensitive adhesive tape passes the flammability test as provided for in FAR25.853(a)app.F.Part1(a)(1)ii.
