A combination of materials that may be formed through an extrusion process. The resulting product has at least two layers. By coextruding multiple layers of at least two types of materials together, the final product may have improved mechanical, thermal, electrical, and other properties as compared to the original materials used. Additionally, by using an additive, filler, or doping material in at least one layer of the final product during the extrusion process, the mechanical, thermal, electrical, or other properties of the final product may be further improved.

A polymer floor element includes a decorative top layer on a substrate made of polymer. The floor element has a rectangular or square surface, for which it is valid that for a strip of the floor element with a first point Q defined as a vertex of the strip, and a point P at a distance of 40 cm with respect to Q along a side of the strip, suspended over a rod with diameter 2 cm with its side on which P and Q are defined, perpendicular to the axis of the rod, so that P is located in the vertical direction at the highest point where the floor element touches the rod. The strip, with point Q along one side, hangs down from the rod under the strip's own weight; the straight line PQ intersects the vertical through P at an angle less than 15°.

A foam-molded product including a foam layer, and a skin layer covering the foam layer, in which the maximum diameter of bubbles in the foam layer is 0.90 mm or less; and a method for manufacturing a foam-molded product and a method for suppressing an appearance defect of a foam-molded product, including an injection process and a foaming process, wherein the foam-molded product after molding includes a foam layer and a skin layer covering the foam layer, the skin layer having an average thickness of from 0.3 mm to 0.7 mm, and wherein expanding of the volume of the cavity includes performing a core-back process of the mold such that a thickness of the foam-molded product after molding is within ±0.2 mm of a predetermined target thickness.

A system for protecting a hard disc drive (HDD) from acoustic energy in a chassis comprises a set of foam strips formed from acoustically absorptive material. Each foam strip has a thickness such that, when the HDD is installed in a chassis, the acoustically absorptive material is in a substantially uncompressed state. Foam strips are separated by an airflow path width, wherein two foam strips, a first surface of an HDD and a second surface form an airflow path. The second surface may be a surface of an adjacent HDD or a wall of the chassis. Each foam strip has a width and length configured for absorbing acoustic energy that would otherwise propagate through the airflow path.

The present invention relates to a polypropylene composition comprising —10 to 50 wt. % of recycled polypropylene (R-PP) and/or linear polypropylene (L-PP); —40 to 89.95 wt. % of a high melt strength polypropylene (HMS-PP) having an F30 melt strength of more than 25.0 cN and a v30 melt extensibility of more than 205 mm/s, wherein the F30 melt strength and the v30 melt extensibility are determined according to ISO 16790:2005; and —0.05 to 10 wt. % of a nucleating agent (NA); a foamed sheet formed from the polypropylene composition; an article comprising the foamed sheet and a process comprising the step of forming the polypropylene composition. Furthermore, the invention is further directed to the usage of the polypropylene composition for the formation of foamed sheets.

The present invention relates to a composite coating for an inner tube delimiting a passageway for a fluid for obtaining a pipe for conveying fluids in HVACR systems.

Various systems are provided herein for sealing and dispensing the contents of containers. The systems can include openings that may be movable relative to one another between sealed positions and dispensing positions.

A floor panel for forming a floor covering comprises a substrate consisting of at least two substrate layers differing in density and, on at least one pair of opposite edges, is provided with coupling parts of the so-called push-lock type. Vertically active locking surfaces, where they cooperate in the coupled condition of two of such floor panels, define a tangent line which is horizontal or does not deviate more than 50 degrees from the horizontal. The locking surfaces are situated closer to the upper side of the first substrate layer than to the lower side of the first substrate layer.

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.
