摘要：A wound dressing material, particularly for burns, compris a sheet of synthetic plastics material which is permeable to water vapor and air, preferably a polyurethane produced by polymerization of an isocyanate capped polyoxyethylene polyol, without any substantial amount of water prent, using a cross-linking agent which reacts with the isocyanate groups. The polyol and cross-linking agent, and preferably also an alkylene oxide surfactant, are agitated to form an aerated mix, spread on a relea paper, and heated so that polymerization begins in the expod upper surface, so as to form a sheet having a den outer region which is impervious to liquids, a cellular region beneath the den region, and a smooth glazed surface for application to a wound.
