Abstract: The invention relates to a pressure-sensitive adhesive strip composed of at least three layers, comprising an inner layer F composed of a non-extensible film carrier, a layer SK1 composed of a self-adhesive composition arranged on one of the surfaces of the film carrier layer F and based on a vinylaromatic block copolymer composition foamed with microballoons, a layer SK2 composed of a self-adhesive composition arranged on the opposite surface of the film carrier layer F from the layer SK1 and based on a vinylaromatic block copolymer composition foamed with microballoons, where the mean diameter of the voids formed by the microballoons in the self-adhesive composition layers SK1 and SK2 is independently 20 to 60 μm.

Abstract: A pressure-sensitive adhesive is to achieve good bond strengths at both high and low temperatures. This aim is accomplished by the adhesive comprising the following components:a) 40-70 wt %, based on the total weight of the adhesive, of at least one poly(meth)acrylate; b) 15-50 wt %, based on the total weight of the adhesive, of at least one synthetic rubber; and c) at least one tackifier compatible with the poly(meth)acrylate(s). The invention further relates to an adhesive tape which comprises at least one layer of the pressure-sensitive adhesive of the invention.
