A panel including at least a substrate of thermoplastic material and a top layer with a printed decor and a translucent or transparent wear layer. The substrate has a thickness larger than one half of the thickness of the entire panel, and the substrate at least includes two layers, where the two layers each include thermoplastic material. A first one of the two layers further includes at least 60 percent by weight of filler materials and a second one of the two layers includes less fillers or is not filled, and is situated above the first one of the two layers.

The invention provides a free flowing copolymer between disparate plastic layers to thermally balance between the two differently expanding/contracting materials. The primer layer or thermal balance layer fully encapsulates the PET layer and can absorb the difference between the internal PET layer with any layer bonded to the encapsulated PET without cracking, bending or pitting and can reset into position when the heating/cooling has ended to make planar plastic core sheets for products such as credit cards, gift cards and the like.

Metal plates are placed on opposed surfaces of two heating plates, the metal plates are heated. Then, a hollow plate is placed between the two heating plates, and the two heating plates are moved toward each other. The metal plates, which are heated to a high temperature, are bonded to the outer surfaces of the hollow plate by thermal fusion caused by the heat of the metal plates. After the metal plates are brought into planar contact with the hollow plate, the heating plates are moved away from each other. The heating plates sandwich the hollow plate only for a very short time. Thus, the heat of the heating plates is not transferred excessively to the hollow plate.

A composite material is capable of suppressing decrease in the strength, which is caused by bending of fibers of a skin material during the time when the composite material is cured. A composite material is provided with a honeycomb core, a first skin material, a second skin material, a thunder-resistant mesh and a resin material; and the resin material is not arranged in a neighborhood portion which is the region corresponding to the region at the front end of the honeycomb core. A first film adhesive is arranged between the first skin material and the honeycomb core; a second film adhesive is arranged between the second skin material and the honeycomb core; and a fourth film adhesive is arranged in the neighborhood portion of the resin material in a weight per square meter, which is lower than those of the first film adhesive and the second film adhesive.

A housing assembly, a method for manufacturing the housing assembly, and an electronic device are provided according to the present disclosure. The housing assembly includes a housing body and a flexible film layer. The housing body has a bottom portion and at least one side wall connected with an outer edge of the bottom portion, and each of the at least one side wall and the bottom portion cooperatively define a bending angle larger than 70 degrees. The flexible film layer is disposed on a first surface of the housing body, and the flexible film layer has an elongation at break higher than or equal to 150%.

Disclosed herein are methods for making asymmetric laminate structures and methods for reducing bow in asymmetric laminate structures, the methods comprising subjecting the laminate structures to at least one thermal cycle comprising cooling the laminate structures to a first temperature near or below room temperature and heating the laminate structures to a second temperature near or below the lamination temperature. Also disclosed herein are laminate structures made according to such methods.

A panel including at least a substrate of thermoplastic material and a top layer with a printed decor and a translucent or transparent wear layer. The substrate has a thickness larger than one half of the thickness of the entire panel, and the substrate at least includes two layers, where the two layers each include thermoplastic material. A first one of the two layers further includes at least 60 percent by weight of filler materials and a second one of the two layers includes less fillers or is not filled, and is situated above the first one of the two layers.

A strengthened glass article has opposing first and second compressively stressed surface portions bound to a tensilely stressed core portion, with the first surface portion having a higher level of compressive surface stress than the second surface portion for improved resistance to surface damage, the compressively stressed surface portions being provided by lamination, ion-exchange, thermal tempering, or combinations thereof to control the stress profiles and limit the fracture energies of the articles.

A panel including at least a substrate of thermoplastic material and a top layer with a printed decor and a translucent or transparent wear layer. The substrate includes three layers, including a lowermost layer, a central layer and an uppermost layer, all made from thermoplastic material, where the thermoplastic material of the central layer is more rigid than the thermoplastic material of the lower most layer and the uppermost layer.

A resin card medium which has a substrate having electronic components mounted thereon and has sophisticated flatness and smoothness realized without providing any layer having holes for absorbing thicknesses of the electronic components; and a method for manufacturing a resin card medium.

A resin card medium laminated body before pressing is prepared by laminating, on a first plastic finishing sheet, a substrate having one electronic component or two or more electronic components installed on one side of the substrate, with the one side, on which the electronic component or electronic components are installed, facing upward, and laminating, on the substrate, mixed paper constituted of plastic fibers and plant fibers, and by subjecting the resin card medium laminated body to hot pressing at a temperature which is a softening point or more of the plastic fibers and less than a melting point of the plastic fibers.
