Abstract: The invention relates to a process for producing shaped articles, where a foam layer which includes a polyurethane foam obtained by foaming a composition including an aqueous, anionically hydrophilicized polyurethane dispersion (I), and drying, is thermoformed where the thermoforming takes place at a temperature of from ?100° C. to ?200° C. and under a pressure of from ?50 bar to ?150 bar, and where additionally during the thermoforming the foam is compressed to ?25% to ?100% of its original volume. The foam can be stabilized using ethylene oxide/propylene oxide block copolymers. The invention further relates to shape articles obtainable in this way, and to the use thereof, preferably as wound dressings.

Abstract: The present invention relates to a process for producing shaped articles comprising, acting on a foam layer in a first region with a pressure of from 0 to 150 bar at a temperature of from 0° C. to less than or equal to 200° C., whereby the foam layer is compressed in the first region to greater than 12.5% to 100% of its original volume; acting on the foam layer in a second region with a pressure of from 50 to 150 bar at a temperature of from 100° C. to 200° C., whereby the foam layer is compressed in the second region from greater than 0% to 12.5% of its original volume; and wherein the foam layer comprises in the first region and the second region a polyurethane foam which is obtained by foaming and drying a composition comprising an aqueous, anionically hydrophilicized polyurethane dispersion.

Abstract: A process for preserving over long storage periods the solderability of tin-lead coatings on copper or copper-based alloys on through hole plated printed circuit boards is described in which an intermediate layer of lead is deposited before the deposition of a tin-lead alloy. Printed circuit boards produced in this manner show an improved soldering behavior.
