Abstract: The invention relates to a contact-adhesive tape which can be removed damage-free and residue-free by stretching the tape substantially within the adhesion plane and which consists of one or more adhesive substance layers, all made of a contact-adhesive substance expanded with micro-balloons, and one or two optional intermediate backings. The disclosed contact-adhesive tape consists exclusively of the aforementioned adhesive substance layers and optional intermediate backings, and the one external upper surface as well as the one external lower surface of the contact-adhesive tape are formed by said adhesive substance layer or layers.

Abstract: Pressure-sensitive adhesive (PSA) strips, configured or adapted for the residue-free and non-destructive removal by which by substantially expanding it in the plane of adhesion, are provided. The PSA strips comprise at least one adhesive compound layer consisting of a PSA compound, constituted by vinyl aromatic block copolymers and one or more adhesive resins, at least 75 wt.-% (relative to the total amount of resin) of a resin being selected that has a DACP (diacetone alcohol cloud point) of greater than −20° C., and a softening point (ring & ball) of greater than or equal to 70° C., and the PSA compound has being foamed.

Abstract: The invention relates to a pressure-sensitive adhesive strip comprising at least one layer SK1, preferably exactly one layer SK1, of a self-adhesive composition 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 layer SK1 is 45 to 110 μm.

Abstract: The present invention relates to a method for producing a layer of self-adhesive composition at least partially foamed with microballoons, wherein a foamable layer of self-adhesive composition comprising expandable microballoons and disposed between (i) two liners, (ii) a liner and a carrier, or (iii) a liner and a further layer of self-adhesive composition which (a) is not foamable or (b) is foamable and typically comprises expandable microballoons, is heat-treated at a temperature suitable for foaming for a period such that after the subsequent cooling of the layer the desired degree of foaming is attained, characterized in that the two liners or the liner during the foaming remain or remains adhering substantially completely on the respective surface of the foamable layer of self-adhesive composition on which they or it are or is disposed.

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.
