Abstract: A polymer thick film carbon black composition comprising 6-13 wt % conductive carbon black powder; and 87-94 wt % organic medium comprising thermoplastic polyurethane resin dissolved in an organic solvent may be used to form the resistive element of heaters in applications where significant stretching is required, particularly on substrates that can be highly elongated and, in particular, that can be used in wearable garment applications.

Abstract: An unconsolidated impact and penetration resistant laminate comprises a plurality of cross-plied sheets, each cross-plied sheet further comprising (i) first and second layers of fibrous or non-fibrous ultra-high molecular weight polyethylene and (ii) first and second layers of thermoplastic adhesive, each adhesive layer having a basis weight of no greater than 5 gsm, wherein (a) the layers of polyethylene and thermoplastic adhesive alternate within the sheet, (b) at least 50 percent of the polyethylene layers are arranged such that the orientation of the first polyethylene layer is offset with respect to the orientation of the second polyethylene layer, and (c) the plurality of cross-plied sheets form a stack that, when subjected to compaction at a pressure of 255 bar and a temperature of 132 degrees C., will not suffer a pressure loss greater than 8 bar within the first two minutes as measured by Test Method B.

Abstract: An impact penetration resistant laminate comprises a plurality of alternating layers of (i) non-fibrous ultra-high molecular weight polyethylene monolayers and (ii) a thermoplastic adhesive, the adhesive having a basis weight of no greater than 5 gsm and a zero-shear-rate viscosity, determined from an oscillating disc rheometer in a frequency sweep between 0.1 rad/s and 100 rad/s, conducted per ASTM D 4440 at 125° C., and calculated from fitting to a Carrea-Yasuda four parameter model, of at least 1500 Pa-s, wherein (a) at least 90 percent of the monolayers are arranged such that the orientation of one monolayer is offset with respect to the orientation of an adjacent monolayer, and (b) the modulus of elasticity through the thickness of the laminate is at least 3 GPa.

Abstract: An impact resistant composite article has two or more layers of ballistic fabric and ionomer layers disposed between the fabric layers. The ionomer is highly neutralized so that it has essentially no melt flow. A process also for making such a composite article that involves deposition of an aqueous colloid of the ionomer onto the fabric, followed by drying.

Abstract: Flame resistant, selectively permeable laminates are provided. In various embodiments, the laminates are useful for fabrication as a protective article and are both flame resistant and substantially impermeable to hazardous chemical and biological agents, but sufficiently permeable to water vapor that, if worn as protective apparel, it is both protective and comfortable to wear.
