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.

Stretch-release adhesive articles with tunable mechanical properties are provided. The articles include a stretchable carrier extending along a first direction and including a first major surface and a second major surface opposite the first major surface. At least one of the first and second major surfaces of the stretchable carrier is a stretch-releasable adhesive surface, and the stretchable carrier includes a pattern of slits distributed thereon and configured to deform upon a stretch on the stretchable carrier to elongate the stretchable carrier.

Disclosed by embodiments of the present application are an optical adhesive tape and a display panel. The optical adhesive tape includes a first buffer layer and an opening disposed at a position corresponding to the fingerprint identification area and configured to penetrate the first buffer layer. The opening is filled with a removable filler including a second buffer layer.

An object of the invention is to provide a moisture-curable polyurethane resin composition containing a biomass raw material and having excellent adhesiveness to a fabric (particularly, a water-repellent fabric) and excellent film strength. The invention provides a moisture-curable polyurethane hot-melt resin composition containing: a urethane prepolymer (i) having an isocyanate group, which is a reaction product of a polyol (A) and a polyisocyanate (B), the polyol (A) containing a polyester polyol (a1) containing, as raw materials, a biomass-derived polybasic acid (x) and a biomass-derived glycol (y), and another polyester polyol (a2). In addition, the invention provides an adhesive containing the moisture-curable polyurethane hot-melt resin composition.

A pressure-sensitive adhesive layer consists of a dried product of a water-dispersed pressure-sensitive adhesive composition. The water-dispersed pressure-sensitive adhesive composition contains a water-dispersible polymer, water, and polyacrylic acid. The polyacrylic acid content is above 0.1 parts by mass and 7 parts by mass or less with respect to 100 parts by mass of the water-dispersible polymer. A thickness of the pressure-sensitive adhesive layer is 10 μm or more and 40 μm or less.

Articles (100, 200, 300) comprising first (101, 201, 301) and second layers (102, 202, 302) each having first and second opposed major surfaces and between the first and second layers a series of first walls (110, 210, 310) having aspect ratios between 1.5 and 5 providing a series of microchannels, and methods for making the same. Embodiment of coextruded articles described herein are useful, for example, in cushioning applications where high levels of compression are desired.

The present invention relates to a redetachable adhesive tape having a carrier based on a crosslinked polyurethane and an adhesive layer based on vinylaromatic block copolymer, to a method for producing the adhesive tape and the use of the adhesive tape in the production of electronic components.

A double-sided adhesive tape is provided for bonding two or more adherends. The double-sided adhesive tape has satisfactory rollability, excellent reworkability after cleavage, and excellent shear holding characteristics at high temperatures. The double-sided adhesive tape includes a foam base, a resin layer (A1) disposed in direct contact with one surface of the foam base, an adhesive layer (B1) disposed on A1 on a side opposite to the foam base, a resin layer (A2) disposed in direct contact with another surface of the foam base, and an adhesive layer (B2) disposed on A2 on a side opposite to the foam base. A1 and A2 are each formed of a crosslinked product of a composition containing a resin having a hydroxy group and a compound reacting with the hydroxy group, and the tensile modulus of each of A1 and A2 is 50 MPa or more and 1000 MPa or less.

The present invention relates to an adhesive sheet laminate which comprises a substrate layer composed of a thermoplastic resin composition (A) containing a polypropylene-based resin as a main component, an adhesive layer composed of a thermoplastic resin composition (B) containing a specific thermoplastic resin (b) as a main component and having a melt flow rate of 0.1 to 30 g/10 min, and a release layer composed of a thermoplastic resin composition (C) containing a specific thermoplastic resin (c) as a main component and having a melt flow rate of 0.1 to 30 g/10 min, and which has a tensile elastic modulus of 2000 MPa or more.
