Abstract: The present disclosure relates to a silicone rubber foam layer obtainable by a process that includes providing a substrate; providing a first solid film and applying it onto the substrate; providing a coating tool provided with an upstream side and a downstream side, wherein the coating tool is offset from the substrate to form a gap normal to the surface of the substrate; moving the first solid film relative to the coating tool in a downstream direction; providing a curable and foamable precursor of the silicone rubber foam to the upstream side of the coating tool thereby coating the precursor of the silicone rubber foam through the gap as a layer onto the substrate provided with the first solid film; providing a second solid film and applying it along the upstream side of the coating tool, such that the first solid film and the second solid film are applied simultaneously with the formation of the adjacent layer of the precursor of the silicone rubber foam; foaming or allowing the precursor of the silicone rubber foam to foam; curing or allowing the layer of the precursor of the silicone rubber foam to cure thereby forming the silicone rubber foam layer; optionally, exposing the layer of the precursor of the silicone rubber foam to a thermal treatment; and optionally, removing the first solid film and/or the second solid film from the silicone rubber foam layer.

Abstract: A three dimensional flame barrier is described herein. The three dimensional flame barrier comprises a flame resistant material, wherein the flame resistant barrier has a complex geometry that is defined by a height, width and length, wherein the height of the complex geometry is substantially greater than the thickness of the flame resistant material from which it is formed wherein the flame resistant material comprises inorganic fibers, inorganic particles and an inorganic binder. In some embodiments, the flame barrier article can further comprise a fire protection coating disposed on a first major surface of the flame barrier material.

Abstract: The present invention provides a method for determining the retroreflectivity of a garment having attached thereto retroreflective patches. According to the method of the present invention each retroreflective patch of said garment is subdivided into discrete subelements. The dependence of the retroreflectivity on the orientation of said subelement can be calculated using retroreflectivity data containing measured retroreflectivity parameters. The retroreflectivity of a subelement is determined from the retroreflectivity data associated with the subelement and the 3-dimensional orientation of the subelement on said garment in a model of the garment which may be a computer generated 3D model of the garment when worn by a user. The retroreflective performance of the garment in a desired view is calculated from the contribution of the subelements visible in a desired view.
