Abstract

The present invention relates to methods for forming foamed polymeric articles and articles produced by such methods. In particular, the invention relates to a method of forming a foamed polymeric article comprising a foamed polymeric material (17) sandwiched between two layers (7,13) in a mold (1,9), wherein the polymeric material comprises a chemical blowing agent, and the expansion of the polymeric material during foaming causes the outer layers of the article to deform so as to provide good contact with the surfaces of the mold. The present invention further relates to foamed polymeric articles formed by the method of the invention having complex surface geometry and/or good continuity of the foam.
