Floor coverings having a greige good, an adhesive layer, and a secondary backing material. The greige good has a primary backing component having adjoined first and second portions, and a plurality of fibers. The secondary backing material has an attached portion and a first exposable portion, with the attached portion adhered to the first portion of the primary backing component by contact with the adhesive layer. The second portion of the primary backing component is unattached to the first exposable portion of the secondary backing material, and the first exposable portion defines a portion of the first end edge of the floor covering. The second portion of the primary backing component is selectively moveable relative to the first portion to a position in which at least a portion of the second portion of the primary backing component does not overlie the first exposable portion of the secondary backing material.

A tempered glass protective film for ultrasonic fingerprint recognition function is configured to solve the problem that the echo energy received by the ultrasonic fingerprint sensor is low and the clear fingerprint image cannot be obtained after the tempered glass protective film is used on the electronic device. The tempered glass protective film includes a glass layer, a first glue layer and a second glue layer arranged in a top-to-bottom sequence, in which the first glue layer is an OCA glue layer, and the second glue layer is a silicone layer or a PU glue layer. The thickness of the OCA glue layer gradually decreases from the edge to the center, and correspondingly, the thickness of the tempered glass protective film gradually decreases from the edge to the center. The tempered glass protective film has better impact resistance while improving the echo energy received by the ultrasonic fingerprint sensor.

Provided is a laminate sheet in which a first sheet, a PSA layer and a second sheet are laminated in this order. Of the first and second sheets, at least one is a release liner having a release face on the side facing the PSA layer. The PSA layer has a thickness of 200 m or greater. The first sheet has a tensile modulus of 1000 MPa or greater and the second sheet has a tensile modulus of 500 MPa or less.

A surface protection film includes an adhesion layer that includes a blend of a first hydrogenated styrene block copolymer, a second hydrogenated styrene block copolymer different from the first hydrogenated styrene block copolymer, and polyethylene. An Adhesion Build Value of the surface protection film is less than 2.5 after the adhesion layer has been attached to a textured polycarbonate substrate and heated to 90 C. for 10 minutes.

The invention provides for an optically clear adhesive (OCA), a display panel, and a method of manufacturing the OCA. The OCA includes an OCA layer and a polyurethane resin layer which are disposed in a stack. The polyurethane resin layer mixes with the OCA layer. The method includes a plurality of steps of: providing a lower release film, manufacturing the OCA layer, and manufacturing the polyurethane resin layer. The display panel includes a backplate layer, a display layer, a touch control layer, a polarizer, and a flexible plate which are sequentially disposed on each other. The OCA is disposed between the backplate layer and the display layer and/or is disposed between the display layer and the touch control layer and/or is disposed between the touch control layer and the polarizer and/or is disposed between the polarizer and the flexible plate.

The present invention provides an adhesive tape or sheet with a separator comprising an adhesive tape or sheet comprising a support layer and an adhesive layer laminated on the upper side of the support layer; and a separator located on the upper side of the adhesive layer, wherein the separator has a three-layer structure in which a first A layer, a B layer, and a second A layer are laminated in this order from the lower side; the first A layer and the second A layer are formed of the same type of unstretched polyolefin film, and the B layer is formed of a biaxially stretched polyolefin film; and the thickness of the first A layer is 70% or more and 130% or less of the thickness of the second A layer.
