A film that is excellent in easy cuttability and linear cuttability and suppressed in breakability in processing, and a roll and a pressure-sensitive adhesive tape that includes the film. The film has the tensile strength in one direction is 1.1 to 2.5 kN/m and the tensile strength in a direction orthogonal to the one direction is 3.0 to 10 kN/m, or the tensile strain at tensile strength in one direction is 50 to 150% and the tensile strain at tensile strength in a direction orthogonal to the one direction is 8 to 20%.

A transparent heat-insulating film is provided, wherein the transparent heat-insulating film includes a base layer including a first surface and a second surface, a hard-coat layer, a silver nanowire layer, and a protective layer including an inner surface and an outer surface. The hard-coat layer and the silver nanowire layer are disposed between the first surface of the base layer and the inner surface of the protective layer. A temperature of the second surface of the base layer is T1 (° C.), a temperature of the outer surface of the protective layer is T2 (° C.), and a temperature difference between T1 and T2 (T1−T2) is ΔT. When T1=50-100° C. and the base layer and the protective layer reach thermal equilibrium, ΔT=0.15T1−0.35T1.

In an embodiment, a multifunctional material system is provided and can include a variable-permeability layer, a desiccant containing layer, and a vapor-permeable supporting layer. The variable-permeability layer can have a vapor permeability that increases with increasing relative humidity. The desiccant containing layer can be adjacent the variable-permeability layer. The vapor-permeable supporting layer can be positioned adjacent at least one of the variable-permeability layer and the desiccant containing layer. Water moves in a first direction from the variable-permeability layer to the desiccant layer when relative humidity is greater adjacent the variable-permeability layer than the desiccant layer. Water moves a second, opposing direction, from the desiccant containing layer to the variable-permeability layer when the relative humidity is greater adjacent the desiccant containing layer than the variable-permeability layer. The rate of water motion in the first direction is greater than the second direction when the humidity gradient is reversed.

The present invention is directed to a cover window assembly comprising a multi-layer films of polymeric and inorganic materials for a variety of articles, and the related articles and methods. The cover window assembly exhibits high resistance to strain and impact damage for the articles including display devices, particularly flexible display devices.

A building panel, such as a floor panel, having a core comprising at least one or more of a thermoplastic material, a thermoset material, a mineral based material or a combination thereof. The building panel further including a first arrangement, arranged on said core, having a surface layer and a sublayer, where the sublayer is arranged between the core and the surface layer.

A process for making a card includes the steps of forming a core layer having a first surface and a second surface, disposing an uncured decorative ceramic layer of ceramic particles disposed in a resin binder over the first surface of the core layer, such as by spray coating, and curing the uncured decorative ceramic layer to form a cured decorative ceramic layer. Card products of the process may have a core layer of metal, ceramic, or a combination thereof that form a bulk of the card.

Disclosed herein are nanostructured plasmonic materials. The nanostructured plasmonic materials can include a first nanostructured layer comprising: a first layer of a first plasmonic material permeated by a first plurality of spaced-apart holes, wherein the first plurality of spaced apart holes comprise a first array; and a second nanostructured layer comprising a second layer of a second plasmonic material permeated by a second plurality of spaced-apart holes, wherein the second plurality of spaced apart holes comprise a second array; wherein the second nanostructured layer is located proximate the first nanostructured layer; and wherein the first principle axis of the first array is rotated at a rotation angle compared to the first principle axis of the second array.

An overmolded thermoplastic article includes a substrate portion molded from a thermoplastic resin compound and an overmold portion molded from a thermoplastic elastomer compound. The thermoplastic resin compound includes thermoplastic polymer resin. The thermoplastic elastomer compound includes thermoplastic elastomer and polysiloxane as a mold release agent, and is free of wax. The overmold portion is bonded onto the substrate portion with a peel strength at least comparable to that of an overmolded thermoplastic elastomer compound containing wax as a mold release agent instead of the polysiloxane. Undesirable effects observed with the use of wax as a mold release agent in overmolded thermoplastic elastomer compounds such as blooming and ease of scratching/marring can be reduced, while desirable properties such as silky feel of the surface of the overmold portion and good bonding of the overmold portion onto the substrate portion can be at least maintained.

Embodiments of a vehicle interior system and methods for forming the same are disclosed. A glass substrate is bent to a curved shape within a mold cavity, and a liquid polymer material is delivered to the mold and is in contact with the curved glass substrate. The liquid polymer is solidified to form a polymer frame that engages the bent glass substrate, and the engagement between the frame and the glass substrate holds the glass substrate in the bent shape. The temperature of the glass substrate during the bending process and formation of the frame are maintained below the glass transition temperature of the glass substrate.
