Abstract: Compositions are provided including an uncrosslinked thermoplastic nitrogen-containing matrix material and composite particles distributed in the matrix material. The composite particles each include a chemical blowing agent particle encapsulated within a shell including an uncrosslinked thermoplastic material. The uncrosslinked thermoplastic material exhibits at least a certain minimum complex viscosity at a decomposition temperature of the chemical blowing agent particle. Also described are foam compositions and articles including the foam compositions, such as a sheet or multilayer construction. Composite particles are further provided. Methods of making the foam compositions are additionally described herein. Also, polishing pads, polishing systems, and methods of polishing a substrate are provided.

CPC classification number: G06T19/20 , G06T2219/2021
Abstract: A method for determining personal protective equipment (PPE) comfort for an individual wearer includes defining a first anatomical shape data representative of an anatomical area of the individual wearer prior to donning a PPE, a second anatomical shape data representative of the anatomical area of the individual wearer after donning the PPE, and comparing the first anatomical shape data with the second anatomical shape data. The method further includes determining a soft skin tissue deformation at a plurality of predetermined anatomical positions based on the comparison between the first anatomical shape data and the second anatomical shape data, and determining a displacement comfort threshold (CTd) value based on the soft skin tissue deformation. The method also includes determining a pressure pain threshold (PPT) value, and determining a comfort metric based on the PPT values and the CTd values. The method also includes generating a notification corresponding to the comfort metric.

Abstract: A ring-shaped cushion for a hearing protector or audio headset. The cushion has a circumferential contact pad for sealing on a wearer's head and an attachment for sealing with an earmuff. The cushion further has a sound insulation tube that inwardly defines an inner space. The sound insulation tube extends between the contact pad and the attachment. The cushion has a ventilation passage that extends entirely through the cushion between an inlet opening in the contact pad and an area outside of the inner space. The cushion may further include one or more physiological sensors to monitor the health of a wearer.

Abstract: A PTSM-coated expandable microsphere comprises a polymer shell enclosing an interior volume containing at least one blowing agent. The polymer shell has an outer surface with photothermal susceptor material disposed on at least a portion thereof. If heated to at least one temperature greater than 25° C., each of the expandable microspheres expands, but does not rupture, the polymer shell by a sufficient amount to at least double the interior volume. A markable comprises a substrate and a viewable layer secured thereto. The viewable layer comprises a binder material retaining the PTSM-coated expandable microspheres. A method of marking a markable article comprises imagewise exposing the PTSM-coated expandable microspheres of the markable article to at least sufficient electromagnetic radiation to cause the PTSM-coated expandable microspheres to expand thereby creating a predetermined image. A marked article preparable according to the method is also disclosed.

Abstract: Reaction mixtures, foams prepared from the reaction mixtures, articles containing the foams, and methods of making the foams are provided. The polymeric material in the foam is formed from a polymerizable composition that includes a di(meth)acrylate oligomer and a monomer having a single ethylenically unsaturated group. The foams are highly filled (e.g., at least 60 volume percent of the foam is the filler) and can be thermally conductive. Although the foams contain a large amount of filler, the foams can be compressed at least 40 volume percent with an applied pressure of 50 pounds per square inch (345 kiloPascals).

Abstract: Open cell foam compositions are provided including a thermoplastic polymeric matrix and at least one filler. In some embodiments of the foam compositions, the filler includes nepheline syenite. Methods of making the foam compositions are described, the methods including (a) obtaining a composite materials containing a first thermoplastic polymer having a filler component and a blowing agent distributed therein; (b) coextruding the composite material with a second thermoplastic polymer and a third thermoplastic polymer to form a three-layer composition, wherein the three-layer composition includes a middle layer comprising an open cell foam formed from the foam composition, and the middle layer is disposed between the first and the second outer layers formed from the second and the third thermoplastic polymers, respectively; and (c) separating the middle layer from each of the first and the second outer layer. The first thermoplastic polymer is different from the second and the third thermoplastic polymers.
