The present invention addresses the problem of providing a flooring material whereby it becomes possible to improve an anti-aging effect of an activity in various facilities. The present invention provides a flooring material containing a stone material, in which the stone material contains silicon dioxide in an amount of 67.0 to 80.0% by mass, inclusive, relative to the whole amount of the stone material.

A board including a plurality of layers having a different composition. At least one of the layers is based on MgO and MgChloride and/or at least one of said layers is based on MgO and MgSulphate. Methods for manufacturing such boards, and methods for manufacturing coated panels include such board.

Ceramic and stone tiles are shown, which are provided with a locking system including a separate strip part connected to vertical and horizontal grooves formed in the tile edge. A set of ceramic or stone tiles including a first tile provided with a first edge and a second tile provided with a second edge wherein the tiles are provided with a locking system for locking the first edge to the second edge in a horizontal direction parallel with a tile surface and in a vertical direction perpendicular to the horizontal direction, said locking system includes a first and a second tongue and a strip part provided with a first and a second locking element.

A flooring panel (50) is provided with a quick-release adhesive sheet (10) such that the flooring panel (50) can be quickly attached to a support surface and removed therefrom. More particularly, the flooring panel (50) includes a top floor layer (52) attached or laminated to the adhesive sheet (10), which underlies the floor layer (52). The top flooring layer (52) can be any type of flooring material, such as vinyl flooring, real or engineered wood flooring, etc. (FIG. 8).

A decorative sheet including: a material sheet of which a surface roughness R1 on a front side is greater than a surface roughness R2 on a back side; a first adhesive layer provided on the front side of the material sheet; a thin film layer provided above the front side of the material sheet via the first adhesive layer; a second adhesive layer provided on the back side of the material sheet; and a sheet support layer provided below the back side of the material sheet via the second adhesive layer, in which each of the layers is integrated as one sheet, and an air layer exists on an interface between the first adhesive layer and a trough of an uneven shape on the front side of the material sheet.

A floor element for forming a floor covering, wherein the floor element comprises a decorative layer made of a ceramic material; a support layer arranged below the decorative layer; and a reinforcing layer arranged in between the decorative layer and the support layer, wherein the support layer comprises edges provided with coupling elements configured to realize a mechanical coupling with coupling elements of an adjacent floor element.

Wall panels for building construction may include a corrugated sheet including a first series of peaks on a first side of the corrugated sheet configured for positioning to face a room interior. The corrugated sheet may also include a second series of peaks on a second, opposite side of the corrugated sheet configured for positioning to face a room exterior. A radiant barrier including a material reflective to heat may be secured only to the second series of peaks. The corrugated sheet may form pockets of air between the radiant barrier and the corrugated sheet.

In a first aspect, a transparent fluoropolymer film includes, a vinyl fluoride polymer, 2 to 8 wt % of an acrylate polymer, and 0.1 to 4 wt % of a triazine UV absorber. After heating at 100° C. for 96 hours, the transparent fluoropolymer film has a 340 nm absorbance of at least 1.5. In a second aspect, a transparent multilayer film includes a polymeric substrate film and a fluoropolymer film. The fluoropolymer film includes a vinyl fluoride polymer, 2 to 8 wt % of an acrylate polymer and 0.1 to 4 wt % of a triazine UV absorber. After heating at 100° C. for 96 hours, the transparent fluoropolymer film has a 340 nm absorbance of at least 1.5.

Protective cover layers for electronic devices are described. In an embodiment, an electronic device includes a display panel and a protective cover layer over the display panel. The protective cover layer includes a transparent support substrate and a hardcoat layer covering an exterior facing surface of the transparent support substrate. The display panel may be a flexible display panel and the protective cover layer may flex with the flexible display panel.

Systems and methods are described herein for manufacturing and using roofing membranes that are faster and easier to install than conventional adhesive-only membrane materials. In some embodiments, membrane materials are surface treated using a plasma flow, e.g., a blown-arc plasma flow, atmospheric plasma, corona plasma, or from portable plasma units, generated by passing a compressed plasma-generating gas through an electrical current to form the plasma-treated roofing membrane. The plasma treatments described herein may be applied as part of the manufacturing process, or in-situ at the site of roof installation. In some embodiments, membrane materials have surface chemistries, roughnesses and other surface characteristics that yield desired adhesion properties.
