Abstract: Shock-resistant adhesive compounds and methods are provided and comprise a) at least about 50% by weight, based on a total weight of the pressure sensitive adhesive, of at least one poly(meth)acrylate, b) about 15-35% by weight, based on the total weight of the pressure sensitive adhesive, of a synthetic rubber component comprising at least one vinylaromatic-butadiene block copolymer and at least one vinylaromatic-isoprene block copolymer, and c) at least one tackifying resin compatible with the synthetic rubber component, wherein a weight ratio of vinylaromatic-butadiene block copolymer(s): vinylaromatic-isoprene block copolymer(s) is about 1.1:1 to about 2.5:1. The methods bond one or more components of at least one portable device with the shock-resistant adhesive compounds.

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 an adhesive film strip comprising at least two, particularly three, layers, which adhesive film strip can be detached without residues and nondestructively by expansive stretching substantially in the adhesion plane, with a carrier on which a first external adhesive compound layer is present on at least one side, wherein the adhesive compound layer consists of adhesive compound formed on the basis of vinyl aromatic block copolymers and adhesive resins, wherein at least 75% of the resin (relative to the overall resin content) is selected with a DACP (diacetone alcohol cloud point) of greater than −20° C., preferably greater than 0° C., and the carrier has at least one layer made from a polyurethane with an elongation at break of at least 100% and a restoring power of more than 50%. A nonpolar hydrocarbon resin or a polyterpene resin is particularly used as the tackifier for the adhesive compound(s).
