ABSTRACT A wound dressing material, particularly for burns, comprises a sheet of synthetic plastics material which is permeable to water vapour and air, preferably a poly- urethane produced by polymerisation of an isocyanate capped polyoxyethylene polyol, without any substantial amount of water present, 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 release paper, and heated so that polymerisation begins in the exposed upper surface, so as to form a sheet having a dense outer region which impervious to liquids, a cellular region beneath the dense region, and a smooth glazed surface for application to a wound.
