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 fluid-filled chamber is provided and includes a first barrier layer, a second barrier layer, a foam structure, and a tensile member. The second barrier layer is secured to the first barrier layer to define an interior void between the first barrier layer and the second barrier layer. The interior void contains a predetermined volume of fluid. The foam structure and the tensile member are disposed within the interior void, whereby the tensile member includes a plurality of fibers extending in a first direction between the first barrier layer and the second barrier layer.

Provided are a composite material and a preparation method therefor. The composite material comprises: a base layer; a first plant fibre fabric located on the upper surface of the base layer; optionally, a second plant fibre fabric located on the lower surface of the base layer; and resins present in each layer. The composite material has a decorative performance and an improved mechanical performance.

Silicone optically clear adhesives compositions and films with pressure sensitive properties are described. The silicone optically clear adhesives compositions are thermal, UV curable, or UV-moisture dual curable. The silicone optically clear adhesives are suitable for sealing and bonding cover glasses, touch panels, diffusers, rigid compensators, heaters, and flexible films, polarizers and retarders in the optical display devices, and are particularly suitable in flexible and foldable displays.

Systems and methods are provided for simulating traction power and control in transportation systems under design conditions and/or utilizing real-time data.

The present invention is directed to packaging films comprising a coextruded film having alternating individual layers of glass and plastic. These packaging films may be used for flexible food and pharmaceutical packaging. These packaging films provide excellent oxygen and moisture barrier protection while having superior flexibility.

Absorbent product including a laminate of at least two plies, wherein the absorbent product has a measured Valley Volume parameter greater than 11 microns and a Pit Density of greater than 25 pockets per sq. cm.

The present disclosure relates to articles and/or constructions with cohesive and to methods of making and using them. Many embodiments provide crush resistance in addition to customizability.

A cushion material with improved vibration absorptivity, and a cushion material manufacturing method for easily obtaining the cushion material are provided. The cushion material (1) includes a foam body (2) having a surface portion (20) formed of an air permeability control surface portion (21) and an air permeability uncontrol surface portion (22), and a covering material (3) configured to cover the air permeability uncontrol surface portion (22). The cushion material manufacturing method is a cushion material manufacturing method for obtaining the cushion material (1), and includes covering the air permeability uncontrol surface portion (22) of the foam body (2) with the covering material (3).

The invention relates to a method to produce a linerboard exhibiting a high bending resistance and a high compression strength, which in turn provides high resistance to interflute buckling and sagging in a thereof formed corrugated board. This is achieved by the inventive combination of an optimized fiber refining level of the furnish in each layer of the linerboard, the separate formation of the top layer and the use of a multi-layer headbox to form the two-layered ply. In addition, the linerboard made according to the invention provides good printing properties in a thereof produced corrugated board, especially in flexographic printing, without the fluting structure being negatively affected.
