摘要:
A double-sided pressure-sensitive adhesive tape for fixing a decorative sheet for speaker, which is extremely small in the generation of VOC, is provided. The present invention relates to a double-sided pressure-sensitive adhesive tape for fixing a decorative sheet for speaker of the invention, comprising a substrate, a pressure-sensitive adhesive layer A disposed on one side of the substrate and a pressure-sensitive adhesive layer B disposed on the other side of the substrate, wherein a total volatile organic compound amount (TVOC amount) is 300 μg/g or less, a diffusion amount of formaldehyde is 3 μg/m3 or less, and a diffusion amount of toluene is 10 μg/g or less. A base polymer of the layer A is preferably formed by solution polymerization using a solvent selected from a solvent composed of only ethyl acetate and a mixed solvent having a proportion of ethyl acetate of 90% by weight or more.

摘要:
The present invention provides a double-sided pressure-sensitive adhesive sheet using a plastic film substrate, ensuring good laminating workability and no elongation or rupture at the lamination even when used in a narrow or long form, where the double-sided pressure-sensitive adhesive sheet has excellent adhesive property and at the same time, exerts excellent peelability (releasability) without causing an adhesive residue at the separation. The present invention relates to a double-sided pressure-sensitive adhesive sheet comprising a plastic film substrate; and a pressure-sensitive adhesive layer on both sides of the plastic film substrate, wherein a 180° peeling pressure-sensitive adhesive force of a surface (surface A) of one of the pressure-sensitive adhesive layer to a stainless steel plate as measured at a tensile speed of 300 mm/min is 8 N/20 mm or more, and an adhesive residue is not generated in the releasability evaluation test.
摘要:
A double-sided pressure-sensitive adhesive (PSA) sheet 11 has, on each side of a plastic film substrate 1, a PSA layer 3 provided through an undercoat layer 2 containing a compound having an oxazoline group. The PSA layer 3 is formed from a water-dispersed PSA composition. This PSA composition contains an acrylic polymer synthesized by emulsion polymerization of a monomer raw material containing an alkyl(meth)acrylate and a carboxyl group-containing monomer, and a water-dispersed tackifier at a mass ratio of 100:5 to 100 based on solid content. The toluene emission when this PSA sheet is kept at 80° C. for 30 minutes is 20 μg or less per gram of the sheet.
摘要:
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.
