Abstract

1,211,981. Flexible sheets of cellular synthetic resin. COMPAGNIE DE SAINT-GOBAIN. 7 Jan., 1969 [6 Feb., 1968], No. 957/69. Headings C3C and C3P. A flexible sheet of cellular synthetic resin, is made by making a sheet from agglomerated beads of the resin which have been expanded and in which no expanding agent capable of further expanding the beads remains, and subjecting the sheet to a compression stage followed by treatment with steam. The sheet may be made by heating beads of cellular polystyrene with steam and then compressing them.
