The present disclosure generally relates to conformable stretch release adhesive and/or stretch-releasable, adhesive articles that are capable of attaching or adhering to a substrate and that can be removed from the substrate without causing damage to the substrate. The present disclosure also generally relates to methods of making and using such adhesive articles.

The present disclosure provides adhesive mounting articles that permit sliding movement along a primary path, even while the article is fixed between a mounting object and a mounting surface. The adhesive articles can allow user precise control over the location and orientation of his or her mounting object, particularly frames.

A highly-dielectric, elastic structure includes an elastic body that is highly-dielectric and includes a polymer matrix that including 1000 pbw of a polydimethylsiloxane (PDMS) base and 100 pbw of a PDMS curing agent, and has a tensile strength of 0.1 to 10 MPa; and 22.4 pbw of carbon black that is surface-treated with octadecyltrimethoxysilane (ODTMS) in an amount of at least 0.707 mmol per 22.4 pbw of the carbon black, and that is dispersed in the polymer matrix and cured; and an adhesive electrode that is stretchable, that is disposed on the elastic body, and that includes a polymer adhesive including a 500 pbw of a thermosetting silicone-based polymer adhesive including a curable polymer and a curing agent; and a conductive filler comprising 500 pbw of silver particles and 4000 pbw of a carbonaceous material that is a multi-walled carbon nanotube that are dispersed in the polymer adhesive and cured.

An adhesive article adapted for removable adhesive bonding between any shaped surfaces of the objects, includes stretch release mesh layers. The non-adhesive mesh layers are sequential release type strips with affixed lobes attached on sides and front back portion of the mesh strips which are stretched for progressive release of the surfaces of the adhesive strip from the surfaces of the objects and provide separation between each other. Another central mesh, provides a sequential release from the major surfaces between adhesive strips. This sequential release reduces the incidence of unwanted damage to surface and also able to hold heavy weight with that adhesive article. To prevent unwanted damage during movement between the surface of objects and adhesive strips and between the major surfaces of adhesive strips in the removal process and therefore provides successful sequential release of the surfaces of the objects.

The present invention relates to an adhesive tape of thickness 40 to 300 μm that can be redetached without residue or destruction by stretching essentially in the plane of the bond, comprising at least one carrier of thickness 10 to 150 μm comprising at least one layer based on preferably uncrosslinked thermoplastic polyurethane that has typically been produced by means of extrusion and has a Shore A hardness of not more than 87, where the carrier has a ratio of force at 400% elongation F.sub.400% to breaking force F.sub.break of not more than 45%, and on which a pressure-sensitive adhesive layer is disposed on at least one side, and wherein the adhesive tape has a ratio of stripping force F.sub.strip to breaking force F.sub.break of less than 60%. The invention also relates to an adhesive tape of thickness 40 to 300 μm that can be redetached without residue or destruction by stretching essentially in the plane of the bond, comprising at least one carrier of thickness 10 to 150 μm comprising at least one layer based on preferably uncrosslinked polyurethane that has been produced from a dispersion and has a modulus at 100% elongation of not more than 1.8 MPa, where the carrier has a ratio of force at 400% elongation F.sub.400% to breaking force F.sub.break of not more than 30%, and on which a pressure-sensitive adhesive layer is disposed on at least one side, and wherein the adhesive tape has a ratio of stripping force F.sub.strip to breaking force F.sub.break of less than 60%. The invention also relates to a process for producing the adhesive tapes and to the use thereof for bonding of components in electronic devices.

The invention relates to an adhesive film strip comprising at least two, particularly three, layers, which adhesive film strip can be detached without residues and nondestructively by expansive stretching substantially in the adhesion plane, with a carrier on which a first external adhesive compound layer is present on at least one side, wherein • the adhesive compound layer consists of adhesive compound formed on the basis of vinyl aromatic block copolymers and adhesive resins, wherein at least 75% of the resin (relative to the overall resin content) is selected with a DACP (diacetone alcohol cloud point) of greater than −20° C., preferably greater than 0° C., and • the carrier has at least one layer consisting of a polyurethane with an elongation at break of at least 100% and a restoring power of more than 50%. A nonpolar hydrocarbon resin or a polyterpene resin is particularly used as the tackifier for the adhesive compound(s).

A battery assembly includes a battery that has a top surface surrounded by a circumferential edge; and a removable tab attached to the top surface. The removable tab includes a first tab end and an oppositely disposed second tab end; a gripping region disposed adjacent to the first tab end; and a battery cell attachment region disposed adjacent to the second tab end and attached to the top surface of the battery. The battery cell attachment region has first and second oppositely disposed sidewalls, wherein at least one of the first and second sidewalls is curved inwardly away from the circumferential edge of the battery such that a portion of the top surface of the battery is exposed between the sidewall and the circumferential edge of the battery.

A pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer having an adhesive strength reducible by an adhesive strength-reducing action. For example, the pressure-sensitive adhesive layer is a thermally releasable pressure-sensitive adhesive layer (11), and the adhesive strength-reducing action is heating of the pressure-sensitive adhesive layer (11). This pressure-sensitive adhesive sheet for build stage use is suitable for allowing an object to be formed over a build stage of an additive manufacturing apparatus to be attached to the build stage during building up, and to be readily detached from the build stage after building up. An additive manufacturing apparatus can employ the pressure-sensitive adhesive sheet for build stage use and includes a build stage, and adhesive strength-reducing means for performing an adhesive strength-reducing action to a pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet for build stage use affixed to the stage.
