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: 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.

Abstract: Polymeric multilayer material includes an adhesive layer having first and second opposed major surfaces. A first foam layer is joined to the first major surface and includes a first plurality of expandable microspheres. A first skin layer is attached to the first foam layer and is free of the first plurality expandable microspheres. A second foam layer is joined to the second major surface of the internal adhesive layer and includes a second plurality of expandable microspheres dispersed therein. A second skin layer is attached to the second foam layer and is free of the second plurality of expandable microspheres. A portion of the first expandable microspheres of the first foam layer and of the second foam layer is at least partially embedded within the adhesive layer. Embodiments, of polymeric multilayer materials described herein are useful, for example, as wearable medical or athletic support components. The materials can also be used as protective wrappings. For example, the materials can be wrapped around a sharp corner of an article, building, etc.

Abstract: Compositions and films are described comprising a polylactic (PLA) polymer and a copolymer comprising a first moiety comprising a C12-C30 alkyl group and a second moiety that is miscible in the composition. Suitable first moieties include a C12-C30 alkyl (meth)acrylate or a polyvinyl alcohol comprising pendent C12-C30 alkyl groups. Suitable second moieties include C1-C10 (meth)acrylic acid or ester thereof, vinyl acetate and ethylene vinyl acetate. The aforementioned composition may be used to form a release layer of an adhesive article such as a pressure sensitive adhesive tape. The films may be a monolithic film or a film layer of a multilayer film. The release layer may be disposed upon a substrate layer that may also comprise PLA. The films are produced by melt extrusion of the aforementioned composition and may be oriented.

Abstract: A shim stack foaming die for making foam slabs comprises a plurality of shims that are layered together under pressure to form a shim stack, wherein the shims combine to collectively define a plurality of die orifices in a working face, to define a main body of the shim stack foaming die, and also to define a plurality of die cavity that is fluidly connected to the plurality of die orifices. And articles foamed from the shim stack foaming die have found wide use in various applications, thermal or acoustic insulation, reinforcing layers and/or space-filling layers, and so on.
