An absorbent wound dressing comprises a hydrophilic porous substrate and polymer-stabilized silver nanoparticles distributed throughout the porous substrate. The silver nanoparticles have a particle size din the range of about 45 nm to about 85 nm and the silver nanoparticles are present in the substrate in an amount of about 0.16% to about 1.5% by weight of the total weight of the substrate. The wound dressing produces a 7-day log reduction of 4 or more for bacteria in accordance with the Modified AATCC Test Method 100. The wound dressing is also non-cytotoxic in accordance with ISO 10993-5 standard procedure for medical device cytotoxicity assessment.

A flame retardant composition for producing a resulting polyurethane foam, a flame retardant process for producing a resulting polyurethane foam, and a resulting polyurethane foam produced by a flame retardant process are described. The resulting polyurethane foam meets the Federal Railroad Administration, National Fire Protection Association, and Federal Transit Administration fire performance testing criteria for cushioning applications in railway, bus, and van industries.
