Abstract: The present invention refers to a thermally debondable tape having a base adhesive layer and at least one thermally releasable adhesive layer including an adhesive and thermally expandable particles. The debondability even after long term storage or use shall be enhanced. In this regard the base adhesive layer has a lower adhesion at expansion temperature of the thermally expandable particles than at room temperature.

Abstract: The heat-expandable removable pressure-sensitive adhesive tape of the present invention includes at least a blowing agent-containing pressure-sensitive adhesive layer A, a microparticle-containing viscoelastic substrate B, a peelable or peel-assisting film layer C, and a pressure-sensitive adhesive layer D. A multilayer structure containing at least the peelable or peel-assisting film layer C and the pressure-sensitive adhesive layer D is arranged on at least one side of the blowing agent-containing pressure-sensitive adhesive layer A where the blowing agent-containing pressure-sensitive adhesive layer A is in direct contact with the peelable or peel-assisting film layer C. The peelable or peel-assisting film layer C can be removed from the blowing agent-containing pressure-sensitive adhesive layer A by heat treatment after storage in an atmosphere of 75° C. for 8 weeks.

Abstract: The present invention relates to an adhesive tape, a method of manufacturing thereof and to uses thereof. More specifically, the present invention relates to an adhesive tape that can be used as such in order to join two entities with their respective surfaces together and/or to attach an entity on the surface of a substrate, whilst the peel adhesion is reduced, i.e. the tape can be removed easily, if desired. The adhesive tape comprising: a layer of a thermally shrinkable polymer, said layer having two surfaces opposite each other, a layer of a pressure sensitive adhesive composition on one of said two surfaces, said pressure sensitive adhesive composition comprising an amorphous polymer, thermally expandable particles and/or at least one blocked isocyanate compound.
