Abstract
1401846 Modifying rigid plastics foams WASSER - SAND - FORSHUNG & VERTRIEBS GmbH 28 June 1972 [29 June 1971] 30172/72 Heading C3C A pre-expanded rigid plastics foam made of individual cellular particles is modified by simultaneously heating and compressing the foam and then subjecting the hot compressed foam to shock cooling (i.e. rapid and forced withdrawal of heat) under compression whereby the surfaces of the foam are hardened. In the example a foamed sheet is placed in a heating chamber 1, having a heating plate 2, where it is heated and pressed, the sheet is then placed in a cooling-chamber 4, having cooling plates, 5, where it is shock cooled under pressure.
