A sheet assembly can be cut into one or more cards. The sheet assembly includes an upper sheet configured to receive a first printing of first indicia for the one or more cards, a polymer core coupled with the upper sheet, and a lower sheet configured to receive a second printing of second indicia for the one or more cards. The lower sheet is coupled with the polymer core with the polymer core disposed between the upper sheet and the lower sheet. The upper sheet, polymer core, and/or the lower sheet is or are formed from a polymer binder with inorganic particles dispersed in the polymer binder. The inorganic particles can have a first density of the inorganic particles that is less than four times a second density of the polymer binder and/or a mass-median-diameter (D.sub.50) of the inorganic particles can be larger than ten microns in size.

The present invention discloses a backplate and a display panel. The backplate includes a substrate layer. Material of the substrate layer includes a doped material. The doped material includes thermally conductive particles.

The present disclosure relates to a breathable layered flexible material comprising at least one polyvinyl chloride (PVC) porous layer or a plurality of PVC porous layers and a support layer. The the pores of the PVC porous layer or plurality of PVC porous layers are obtainable by water evaporation of a water-in-oil PVC emulsion. The pores extend from the PVC layer to the support layer providing the material breathability. The disclosure also relates to a method for preparing the breathable layered flexible material. Upholsteries, in particular car upholsteries, comprising the breathable layered flexible material are also disclosed.

The application relates to a brake pad for a disk brake system and to a disk brake system. The proposed brake pad comprises a back plate having a front side for facing a brake disk of the disk brake system and a friction layer arranged on the front side of the back plate for contacting a friction surface of the brake disk. The brake pad further comprises an underlayer arranged between the front side of the back plate and the friction layer. The back plate comprises a recess. The underlayer extends into the recess of the back plate.

A conductive composite includes a first layer of elastomeric polymer, a layer of conductive fluorofluid on the first layer of elastomeric polymer, and a second layer of elastomeric polymer on the layer of conductive fluorofluid.

This invention involves a cost effective antiviral plastic film with variable physical properties, comprising of at least one thinner surface layer to minimize the amount of the expensive copper nano-powders required to render the film to be antiviral, and one thicker substrate layer with variable physical properties and thickness. The plastic film is made using a co-extrusion cast film or a blown film process so that the antiviral surface layer and the substrate are joined together as they are made into a multilayer film. The physical properties for the plastic film can be varied by using different kinds of polymeric materials such as PE, PP, PVC, Nylons and others. Its low cost combined with variable physical properties make our invented film suitable for making a wide variety of affordable and safer protection products against the COVID-19. Such products include gloves, masks, covers, wrappers, curtains, bags and protective apparels, for use by individuals, healthcare facilities, restaurants and other industries.

An electroceutical system integrated into an article of personal protective equipment (PPE) like a face mask. The system consists of an electrochemical cell consisting of an anodic zone capable of serving as an anode, a cathodic zone capable of serving as a cathode and, optionally, a selectively conductive switch zone electrically couplable to and separating the anodic and cathodic zones and serving to switch on and off current flow between the anodic and cathodic zones.

A filtration article for using in personal protective equipment (“PPE”) that includes one or more layers. The article has an external side for facing side the environment and an internal side for facing the body of a user. The article is air permeable but has a porosity sufficient to entrap and thereby filter selected infectious agents (IAs). The one or more layers comprise structures providing two or more of the following functional features selected from the group of: (1) a structure with oligodynamic materials for inactivating the selected IAs; (2) a structure of carbon fibers or particles for moisture management and/or conductive cooling; (3) a knit or woven structure having yarns in a denier gradient that causes wicking of water from the internal side of the mask toward the external side; (4) an energized or energizable structure that subjects entrapped IAs to current, charged particles, electrostatic discharge, resistive heating, IR heating and/or disruptive electromagnetic energy; and (5) a hydrophobic structure forming an external surface of the external side for repelling droplets and other moisture from absorbing into the surface.
