Floor element comprising a top layer (102) attached to a substrate layer (104), in which the top layer (102) is itself layered, the top layer (102) comprising: —an optional backing layer (122) made of flexible polymer, —a flexible or semi-rigid polymer layer (124), onto or into which optionally at least one reinforcing layer (126) is attached or embedded, and —a finishing layer comprising a decorative layer (132), a wearing layer (134) thereon and optionally a coating (136) thereon; the substrate layer (104) being a rigid substrate layer.

The present invention is in the field of cleaning compositions. In particular it relates to liquid, gelled or pasty cleaning compositions comprising one or more detergent surfactants. The invention provides cleaning compositions comprising water, one or more detergent surfactants and defibrillated primary cell wall material comprising microfibrils. The invention also relates to a method for preparing a cleaning composition comprising water, one or more detergent surfactants and defibrillated primary cell wall material comprising microfibrils, wherein the method includes a high shear treatment step.

A structural panel includes a first skin, a second skin and a core. The core is connected to the first skin and the second skin. The core includes a corrugated sheet of wire mesh that includes a plurality of corrugations. Each of the corrugations extends vertically between and engages the first skin and the second skin.

An anti-microbial partition divider assembly for a cart such as a golf cart is provided. The cart has a passenger seating area, including at least one seat, a roof and a floor. The assembly includes a flexible or beam-rigid partition divider having a substrate layer made of a material which prevents airborne liquid droplets from traveling therethrough.

An acoustic panel for an aircraft propulsion unit, comprises a core and an entry layer in contact with the core, the entry layer comprising lower elements and upper elements, each comprising an inner face, an outer face and at least one through-hole, the inner faces of the lower elements and upper elements being in contact with each other and forming a channel defining a baffle and opening into a cell of the core.

The present invention is directed to an improved gypsum board, such as an improved sound damping gypsum board. The gypsum board comprises a gypsum core including gypsum and a sound damping polymer. The gypsum core includes a first gypsum layer surface and a second gypsum layer surface opposing the first gypsum layer surface. In addition, a first encasing layer is disposed on the first gypsum layer surface and a second encasing layer is disposed on the second gypsum layer surface.

A laminate structure and method of forming is provided. The laminate structure includes a first metal sheet having a first thickness, a second metal sheet having a second thickness, and an adhesive core having an adhesive thickness. The adhesive core is disposed between and bonded to the first and second metal sheets. The first and second metal sheets are made of an aluminum based material and the adhesive core is made of an adhesive material also described as a viscoelastic adhesive material. The laminate structure is configured such that a ratio of the sum of the first and second thickness to the adhesive thickness is greater than either to one (8:1). The laminate structure including the viscoelastic adhesive core is characterized by a composite loss factor at 1,000 Hertz which is continuously greater than 0.1 within a temperature range of 25 degrees Celsius to 50 degrees Celsius.
