Abstract

1412465 Moulding foam scrap SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 13 Oct 1972 47298/72 Heading B5A A method of moulding an article comprises impregnating pieces of cellular plastics material with liquid thermosetting resin so that at least 10% of the total volume of the cells is filled with resin, placing the pieces together with cellular pieces substantially free of resin in a mould or between endless belts and compressing the pieces such that resin is expressed from the resin-rich into the resin-free pieces. Non- impregnatable material such as closed cell plastics material, powder, granular or fibrous filler, e.g. asbestos, glass fibres, mat or cloth, felt or a blowing agent may be mixed locally or through-out the pieces. The pieces may be placed between glass fibre sheets, wrapped in a sheet or placed in a bag of flexible foamed polyurethane prior to moulding. The pieces may comprise polystyrene, polyurethane or elastomers. The resin may be based on epoxys, polyesters or formaldehyde resin's. The pieces may have a length of 0À5-8 ems. and may suffer a volume reduction of 20-80% during moulding. Articles having a square or rectangular shape, e.g. tiled or mosaic flooring and alternating layers of open and closed-cell plastics material may be formed.
