Abstract

1,003,034. Moulding articles. DUNLOP RUBBER CO. Ltd. April 26, 1962 [May 13, 1961], No. 17503/61. Heading B5A. In the moulding of articles of resilient poly urethane foam, latex foam rubber, or another material obtainable from a fluid precursor with the evolution or application of heat, a mould is formed of a synthetic resin composition, such as a polyethylene or polypropylene resin, in which a minor proportion of a wax, e.g. paraffin wax, is present, the heat evolved or applied in the course of the transformation of the fluid precursor into the corresponding solid material being allowed to melt sufficient wax to afford a mould release film. Specifications 1,003,031 and 1,003,033 are referred to.
