Abstract: Housing seals and methods seal off a housing interior from a housing exterior. The housing seals and methods comprise a first elastic adhesive strip and a second elastic adhesive strip, the first and second adhesive strips being arranged between a first housing element and a second housing element. The first adhesive strip comprises a first end portion having a first front side and a first edge face, and a second end portion having a second front side and a second edge face, and is arranged between the first housing element and the second housing element such that the second housing element, with the exception of the application gap, in a closed circulation.

Abstract: Housing seals and methods seal off a housing interior from a housing exterior. The housing seals and methods comprise an elastic adhesive strip that is arranged between a first housing element and a second housing element, wherein the adhesive strip comprises a first end portion having a first edge face, and a second end portion having a second edge face, wherein the adhesive strip and is arranged between the first housing element and the second housing element in such a way that the first and second edge faces lie substantially in a plane, the adhesive strip is arranged between the first housing element and the second housing element in a closed circulation, and the first edge face of the adhesive strip is in contact with the second edge face of the adhesive strip and forms a sealing gap.

Abstract: The invention relates to a sealing element with high sealing effect against air and moisture, which is easy to apply, and which moreover offers the possibility to reopen the sealed gap in an uncomplicated manner. Said solution is provided by an adhesive tape with differing adhesive power on the two main sides, which comprises a) a polymer foam layer and b) an outer adhesive compound layer and/or an outer thermoplastic film on one side of the polymer foam layer and is characterized in that, where the adhesive tape comprises an outer adhesive compound layer, the tape has a greater adhesive power on the side provided with the outer adhesive compound layer than on the opposing side and/or, where the adhesive tape comprises an outer thermoplastic film, the tape has a lower adhesive power on the side provided with the outer thermoplastic film than on the opposing side. The invention furthermore relates to the use of an adhesive tape according to the invention for sealing a joint between two components.

Abstract: Pressure-sensitive adhesives (PSAs) and tapes comprising said PSAs are provided. The PSAs comprise at least one poly(meth)acrylate and at least 40% by volume, based on a total volume of the pressure-sensitive adhesive, of a mixture of at least two fillers. The mixture of at least two fillers comprises at least one filler Fisph comprising or consisting of essentially spherical particles and the PSAs may conduct heat and/or provide electrical resistivity for electronic device or component applications.
