DEBONDABLE PRESSURE SENSITIVE ADHESIVES AND USES THEREOF
The invention relates to on-demand debondable pressure sensitive adhesive and laminating adhesive compositions and uses thereof. The debondable pressure sensitive adhesives and laminating adhesives are applied onto a substrate to form a bond, and upon exposure to electron beam or UV light energy source, the adhesive can dissociate from the substrate. The debondable pressure sensitive adhesives and laminating adhesives are particularly suitable for recycling in a circular economy.
Floor panel
A floor panel has a rectangular and oblong shape, and includes a substrate and a top layer provided on the substrate and forming a decorative side of the floor panel. The top layer is composed of a print provided on a carrier sheet and a transparent thermoplastic layer situated above the print. The substrate has a thickness from 2 to 10 millimeter and forms at least half of the thickness of the floor panel. The substrate is a polyurethane-based substrate and the transparent thermoplastic layer is polyurethane-based. The floor panel has a length of more than 1.1 meters and has a plurality of reinforcing layers situated outside the center line of the substrate. A reinforcing layer may be provided in combination with the substrate and the top layer.
Spacer, laminate of substrates, method for manufacturing substrate, and method for manufacturing substrate for magnetic disk
The area of a spacer that is to be provided between the adjacent substrates in a laminate including a plurality of substrates to keep the adjacent substrates apart from each other is smaller than those of the stacked substrates. When pressure is released to bring the laminate obtained by providing the spacers between the substrates from a pressed state in which 0.60 MPa of pressure is applied to the laminate in the stacking direction into a non-pressed state, an amount of change ΔW in thickness per spacer that is calculated from a change in the thickness of the laminate due to the release of pressure is 30 μm or less.
Skin foam-in-place foamed article and production method thereof
There is provided a skin foam-in-place foamed article comprising a pad (15) and a bag-like outer material (20) covering the pad (15). The outer material (20) has a top layer (21) and a liner layer (22) made of a foamed resin. The liner layer (22) has a closed cell structure. A pad-side skin layer (27a) having a density higher than that of a bulk layer (26) is provided on the liner layer (22), on a side of the pad (15). A corona treatment is applied to the pad-side skin layer (27a).
Filter medium, method for manufacturing same, and filter unit comprising same
A filter medium according to one embodiment of the present invention comprises: a first support having a plurality of pores; a nanofiber web comprising nanofibers disposed on upper and lower portions of the first support and forming a three-dimensional network structure, and a hydrophilic coating layer formed on at least a part of an outer surface of the nanofibers, wherein the hydrophilic coating layer is formed of a hydrophilic coating composition comprising a hydrophilic polymer compound having at least one functional group selected from a hydroxyl group and a carboxyl group and a crosslinking agent comprising at least one sulfone group; and a second support having a plurality of pores interposed between the first support and the nanofiber web.
Composition for non-aqueous secondary battery functional layer, battery component for non-aqueous secondary battery, method of producing laminate for non-aqueous secondary battery, and non-aqueous secondary battery
Provided is a composition for a non-aqueous secondary battery functional layer with which it is possible to form a functional layer that can cause a battery component including the functional layer to display a balance of both high blocking resistance and high process adhesiveness. The composition for a non-aqueous secondary battery functional layer contains a particulate polymer having a core-shell structure including a core portion and a shell portion at least partially covering an outer surface of the core portion. The core portion is formed by a polymer A and the shell portion is formed by a polymer B including not less than 1 mass % and not more than 20 mass % of a cyano group-containing monomer unit.
SPACER HAVING IMPROVED ADHESION
A spacer includes a polymeric hollow profile, including a first and second side wall, a glazing interior wall connecting the side walls to one another; an outer wall arranged parallel to the glazing interior wall and connects the side walls to one another; a cavity surrounded by the side walls, the glazing interior wall, and the outer wall, a moisture barrier on the first side wall, the outer wall, and the second side wall, wherein the moisture barrier includes a multi-layer system having a barrier function including a polymeric layer and an inorganic barrier layer, a metallic or ceramic outer adhesive layer having a thickness of less than 100 nm, a binding layer between the adhesive layer and the multi-layer system and including a polymer selected from oriented propylene, oriented polyethylene terephthalate, biaxially oriented propylene, and biaxially oriented polyethylene terephthalate.
