Provided is a PSA sheet that provides highly reliable adhesion and great stretch removability from adherends. This invention provides a PSA sheet. The PSA sheet exhibits a shear adhesive strength of 0.5 MPa or greater, a tensile strength at break of 10 MPa or greater, and an elongation at break of 300% or greater.

Pressure-sensitive adhesive sheet for portable electronics

This invention provides a PSA sheet that allows prevention or reduction of damage such as fracture with efficient stretch removability. A stretchable PSA sheet is provided, comprising a PSA layer and a film-like substrate supporting the PSA layer. The PSA sheet has a long section. The long section has a tapered segment that extends, tapering to a first end of the length direction and the film-like substrate has a minimum cross-sectional area larger than 0.30 mmin the tapered segment.

Stretchable pressure-sensitive adhesive sheet

Disclosed is a double-faced pressure-sensitive adhesive tape which includes a foam substrate, one pressure-sensitive adhesive layer arranged on or above one side of the substrate, and another pressure-sensitive adhesive layer arranged on or above the other side of the substrate. The adhesive tape has a total thickness of 250 &#x3bc;m or less. The adhesive tape is thin but highly waterproof (sealable against water). The adhesive tape preferably has a tensile strength of 0.5 to 20 MPa for further superior processability.
