Abstract

1,205,336. Polyurethane foam. GOODYEAR TIRE & RUBBER CO. 16 May, 1968 [3 July, 1967], No. 23248/68. Heading B5A. [Also in Divisions B2 and C3] Polyurethane foam having an integral skin may be prepared by causing a polyurethane foamable mixture to foam and set in a mould made from a polyorganosiloxane elastomer or in a mould whose temperature may be adjusted to permit the heat of reaction to be extracted from the surface e.g. an aluminium mould. If desired the mould surface may have an embossed grain. The foam has a coating of a non- discolouring polyurethane over the integral skin.
