Abstract: The present invention relates to a web-shaped adhesive compound which contains at least one poly(meth)acrylate and optionally at least one synthetic rubber; and at least one polyurethane- and/or silicone-based filler. The invention also relates to a process for preparing such an adhesive compound and to the use thereof. The invention further relates to the use of polyurethane- and/or silicone-based fillers for increasing the adhesive power of adhesive compounds containing at least one poly(meth)acrylate and optionally at least one synthetic rubber and/or for increasing the shock performance of such adhesive compounds with respect to adhesive compounds which do not contain any polyurethane- and/or silicone-based filler.

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.
