Abstract

1,148,940. Cellular laminates; moulding expanded polystyrene. COMPAGNIE DE SAINT-GOBAIN. 8 Nov., 1967 [10 Nov., 1966], No. 50751/67. Addition to 1,093,238. Headings B5A and B5N. [Also in Division C3] A method according to claim 1 of Specification 1,093,238 wherein a surface of the cellular product, e.g. of polystyrene is treated to impart a finish to the surface: the above claim 1 is a method for making a cellular product from expanded pearls of synthetic resin comprising heating the pearls to their softening temperature, compressing the softened pearls and cooling under compression. The surface may be treated after the heating of the expanded pearls and before or at the beginning of the compression, or after the cooling by either heating the surface only using infra-red radiation or by applying a film of polyvinyl chloride or polystyrene or sheet of glass fibre or paper to the surface, the film and surface being heated before contact, an adhesive being used if necessary. In Figs. 1 and 2 a sheet is covered with a film using heat and glue respectively and in Fig. 3 the surface is treated by heat only.
