Abstract

In order to achieve, in the case of a plastics moulding, in particular a moulded part such as e.g. a kitchen sink, a washbasin or a work-top or similar, comprising a polymer phase formed from a curable reaction mass and,: embedded therein, a particulate filling material which contains a resin material filled with an inorganic filler, in addition to a good resistance to water whitening a high resistance to crack formation in the hot-cold cycle, it is proposed that the polymer phase contains up to 5 wt %, referred to the plastics moulding, of inorganic additive particles, that the particulate filling material is swellable in the curable reaction mass, that the filled resin material comprises a content of inorganic filler in the range from 50 to 80 wt % with an average particle size of approx. 5 to approx. 100 .mu.m, and that the filling material has a particle size in the range from 60 to 8000 .mu.m and is contained in the plastics moulding in a proportion of approx. 30 to approx. 75 wt %.
