Abstract

1376038 Laminated foam panels IMPERIAL CHEMICAL INDUSTRIES Ltd 25 July 1973 [18 Aug 1972] 38623/72 Heading B5N In the manufacture of laminates by in situ foaming to form a rigid synthetic plastics core between facing layers, at least one of the facings is provided with minute perforations to permit the escape of air and gases from the foam through the facing. The perforations may be preformed or may be formed as the facing is fed to the laminating stage. Suitable facing materials are specified. [GB1376038A]
