Disclosed are polyurethane-based foams. The foams may have one or more vicrucidal/bactericidal agents. The foams may be used as filters that capture and/or inactivate viral particles, such as, virions associated with COVID-19. Also described are methods of making the foams and methods of using the foams.

Construction panel for use as a self-supporting wall or roof panel having a high thermal insulation, comprising a base layer (1) of foamed material provided on both sides with a cover layer (2, 3) of fibre-reinforced, thermo-setting sheet material. The transverse surfaces are covered with a layer of polyurea, polyester or epoxy (5, 7).

A thermoplastic composite article comprising a porous core layer and an open cell skin disposed on a first surface of the core layer is described. The composite article comprises a noise reduction coefficient of at least 0.5 as tested by ASTM C423-17 and a flame spread index of less than 25 and a smoke development index of less than 150 as tested by ASTM E84 dated 2009.

Method for manufacturing on industrial scale of complete, highly reliable, flexible and accurate construction panels that are lightweight and have a very high R-value, wherein the processing is performed, under the control of a digital construction data file, by means of digitally controlled processing devices, such as milling and/or cutting devices. Portions of the construction panel from which the covering layer has been removed by the processing devices (such as the sides of recesses for door and window frames etcetera and optionally milled gutter slots) and portions of the construction panel of which the cover layer requires extra protection, such as portions below ground level, under control of the digital construction data file, are provided with a rigid and highly reliable protective layer of polyurea, polyester or epoxy by means of digitally controlled spraying devices. One or more delta robots can be used for mounting cladding elements such as a brick strip, which robots can be moved by means of the X-Y displacement system above the construction panel controllable from the digital construction data file.

Coated panel with at least a substrate (2) and a top layer applied thereto (3), wherein the above-mentioned top layer (3) comprises at least a decor layer (4) and a translucent or transparent wear layer (5), characterized in that the above-mentioned wear layer (5) comprises a thermally cured acrylate resin or a thermally cured unsaturated polyester resin. Preferably, wherein thermal curing partially or completely cures the resin. In particular, wherein the above-mentioned acrylate resin or unsaturated polyester resin is at least partially cured by means of a thermally initiated radical crosslinking reaction. The invention further relates to a method for the production of such coated panels (1), in particular floor panels.

Light weight fiber-reinforced polymeric structural building panels and methods; sized, configured for fabrication of non-portable wall structures permanently fixed to natural base. The panel main body, and studs, can be fabricated separately, then assembled to each other to complete panel fabrication. Methods for making the main body are hand lay-up, or pultrusion. Studs are typically pultruded, and subsequently prepared having consistent thickness, flat surface, across the width of the stud end wall which is to be mounted to the main body. Foam blocks are between inner and outer layers of the panel. Foam blocks can be prepared in block clusters before assembly to the main body. In the main body, a fibrous layer is between each pair of next adjacent foam blocks. Intercostals extend “y” and “z” dimensions transverse to the length of the main body. Studs can be mounted to the main body using adhesive, mechanical fasteners, or both.

Disclosed herein is a molded article made from two different polyurethane foam laminate materials, which displays both softness and resilience to machine washing. Also disclosed herein is a method of making said foam article.

The present invention relates to a cross-linked polyolefin resin foam obtained by cross-linking and foaming a polyolefin resin composition containing at least a polyolefin resin, wherein the cross-linked polyolefin resin foam has a total light transmittance of 45% or more at the thickness of 0.3 mm or more and less than 1.0 mm, and the cross-linked polyolefin resin foam has a total light transmittance of 30% or more at the thickness of 1.0 mm or more and 5.0 mm or less.

The present invention provides a cross-linked polyolefin resin foam having excellent light transmittance.

The disclosed apparatus, system and method includes at least a protective garment that prevents concussive effects on internal organs. The garment many include a garment body; and, embedded in the garment body, at least one multi-sectional pad. At least two of the multi-sections may comprise: at least one aramid layer; at least one multi-durometer foam layer having a substantially similar surface area to that provided by the at least one aramid layer; and at least one shield layer.

The present disclosure belongs to the technical field of board manufacturing, and relates to a method for preparing a weather-resistant printing board. It specifically includes the following steps: S-1, printing on at least one decorative surface of a core material layer of the board or on an overlay surface of a prefabricated wear-resistant layer to form a printed pattern layer; S-2, forming an adhesive layer between the printed pattern layer and the prefabricated wear-resistant layer or between the printed pattern layer and the core material layer; S-3, bonding the prefabricated wear-resistant layer and the core material layer to obtain the board. The peeling force of the wear-resistant layer of the outer layer of the board obtained by the present disclosure can reach at least 3 MPa, and at the same time, the prefabricated wear-resistant layer is adopted to reduce the requirements on device and production sites.
