Abstract:
The double-sided pressure-sensitive adhesive tape or sheet is a double-sided pressure-sensitive adhesive tape or sheet containing a support having a pressure-sensitive adhesive layer on the both surfaces thereof, characterized in that the double-sided pressure-sensitive adhesive tape or sheet has a total thickness including the thickness of the support and the two pressure-sensitive adhesive layers formed on the both surfaces of the support of 0.003 mm or more and less than 0.03 mm and a breaking strength of from 2 to 26 MPa/10 mm-width. The support preferably has a thickness of from 0.002 to 0.012 mm. As the support, plastic films (especially, a polyethylene terephthalate film) are suitable. The double-sided pressure-sensitive adhesive tape or sheet may have a length of 5 m or more and have a roll-wound form.
Abstract:
Provided is a PSA sheet with low toluene and total volatile organic compound (TVOC) emissions as well as low unpleasant odor level felt by users. The PSA sheet comprises a PSA layer formed of a PSA composition comprising an acrylic polymer emulsion and a tackifier resin emulsion; the toluene and TVOC emissions are at most 20 μg and at most 150 μg, respectively; in a sensory test, 90% of participants evaluate that the unpleasantness of odors emitted from the PSA sheet is less than that of toluene at a prescribed concentration.

Abstract:
The double-faced adhesive tape has a substrate, an acrylic pressure-sensitive adhesive layer, a rubber pressure-sensitive adhesive layer, and a first release liner that is formed on an external side of the rubber pressure-sensitive adhesive layer, and a second release liner that is formed on an external side of the acrylic pressure-sensitive adhesive layer. The first release liner each has a polymer layer and a paper substrate layer. Further, the second release liner each has a polymer layer and a paper substrate layer. Dynamic friction coefficient on the surface of each polymer layer is less than 1.0, when the coefficient is measured according to JIS K7125.

Abstract:
The present invention provides a double-sided adhesive tape for fixing a decorative sheet for speaker, which includes a nonwoven fabric substrate, an acrylic pressure-sensitive adhesive layer A disposed on one side of the nonwoven fabric substrate and an acrylic pressure-sensitive adhesive layer B disposed on the other side of the nonwoven fabric substrate, in which the adhesive tape has a tensile strength in the tape flow (MD) direction of 8 N/10 mm or more and a tensile length in the width (TD) direction of 8 N/10 mm or more. The double-sided adhesive tape is excellent in the adhesion performance to a housing and a decorative sheet for speaker and at the same time, has excellent releasability ensuring that when separating the decorative sheet portion, smooth separation can be attained without leaving a residue of tape or pressure-sensitive adhesive on the housing portion.

Abstract:
A double-sided pressure-sensitive adhesive tape 10 according to an embodiment of the present invention includes: a first pressure-sensitive layer 30 that serves as a pressure-sensitive adhesive surface to a surface plate; a second pressure-sensitive adhesive layer 40 that serves as a pressure-sensitive adhesive surface to a polishing member; and a substrate 20 between the first pressure-sensitive adhesive layer 30 and the second pressure-sensitive adhesive layer 40. In the double-sided pressure-sensitive adhesive layer 10 having such a layer structure, the loop tack adhesive strength of the first pressure-sensitive adhesive layer 30 is 16 N/50 mm or less.
