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.

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

Composite ballistic resistant laminate

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&#xb0; C., and calculated from fitting to a Carrea-Yasuda four parameter model, of at least 1500 Pa-s, wherein

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.
