The present invention relates to a hard coating film having a multilayer-structure and, specifically, to a hard coating film having a multilayer-structure, which has a low Vickers hardness (Hv) value while having an excellent scratch resistance together with flexibility.

An example composite building material includes one or more layers of polymeric fibers, binding agent, and optional fillers, and at least one surface layer of resin-impregnated paper disposed above and/or below the one or more layers. The one or more layers can include a core layer with longer polymeric fibers and top and bottom layers with shorter polymeric fibers. A method of manufacturing the composite building material includes forming the one or more layers, applying the at least one surface layer above and/or below the one or more layers, and heating and pressing the combined layers.

Example embodiments relates to a film having excellent mechanical properties with excellent optical properties such as refractive index, haze, yellow index, and the like, light transmitting laminate, use as a cover film, a multi-layered electronic device, and the like comprising the same.

The film comprises an elastic layer, the elastic layer has a refractive index of 1.48 to 1.58, a low temperature damage index is a difference of a tensile modulus and a tensile strength at a certain temperature, and the elastic layer has a low temperature index of 1,300 MPa or less.

An antiballistic armor-plating component, includes a ceramic body made of a material comprising, as percentages by volume, between 35% and 55% of silicon carbide, between 20% and 50% of boron carbide, between 15% and 35% of a metallic silicon phase or of a metallic phase including silicon.

The present disclosure provides an artificial floor. The artificial floor comprises a plate body with a pad portion on a surface thereof. The pad portion contacts with a subfloor when the plate body is disposed on the subfloor. The plate body could be various kinds of the simulated floor such as linen, wood, or stone. The simulated floor is poor in wear resistance. The vibration or shaking during transportation may cause wearing between the simulated floors so as to damage the surfaces of the simulated floors. The subfloor may have an uneven surface, which may affect the surface flatness of the plate body disposed on the subfloor. Therefore, the pad portion of the plate body could be used as a cushion for the transportation process to protect the collision and wearing between the plate bodies. The pad portion could also be deformed locally to close the surface of the subfloor.

The invention relates to a flooring panel suitable for constructing a floor covering, which panel comprises a core layer and a decorative top layer and a layer situated between the core layer and the decorative top layer which enables improves sound performance.

The present invention relates to a vehicle logo assembly and a method for forming a vehicle logo assembly. The vehicle logo assembly has a housing and a cover, the housing and the cover form an internal space, and a light-emitting assembly and a light-diffusing assembly are accommodated in the internal space, wherein, a coating is provided on the inner side of the cover facing the light-emitting assembly, so as to present a vehicle logo, and the cover is provided with a light-transmitting portion.

A polymer interlayer having improved sound insulation is disclosed. The polymer interlayer comprises: at least one soft layer wherein the soft layer comprises a poly(vinyl butyral) resin composition having a dispersity in composition of at least 0.40 and a plasticizer; and a stiff layer comprising a poly(vinyl butyral) resin composition and a plasticizer; wherein the polymer interlayer has a damping loss factor () (as measured by Mechanical Impedance Measurement according to ISO 16940) of at least about 0.15 measured at two or more different temperatures selected from 10° C., 20° C. and 30° C.

A sound-absorbing cover comprises a first sound-absorbing layer and a second sound-absorbing layer made of foam, a first skin layer of the first sound-absorbing layer and a second skin layer of the second sound-absorbing layer are layered in a state of being made to face each other, and an air layer is provided between the facing surfaces of the first skin layer and the second skin layer. The rigidity of the first skin layer of the first sound-absorbing layer is different from the rigidity of the second skin layer of the second sound-absorbing layer.

Waterproof engineered floor and wall planks have a veneer layer bonded with a plastic composite core, and an underlayer, preferably an underlayer of cork.
