Abstract: A plastic molded body is produced that resembles natural materials such as marble, granite, etc. more closely that the prior products. The plastic molded body has a polymer phase produced from a hardenable reaction material, and a particulate filler material that is dispersed in the polymer phase. The filler material is a resin material that is filled with an inorganic filler. The polymer phase includes up to 60 wt % inorganic aggregate particles based on the weight of the plastic molded body. The filling material has a grain size of 60 to 8,000 ?m and makes up approximately 5 to approximately 65 wt % of the plastic molded body. The filler material has at least 10 volume % of particles that have two or more differently colored, surface-visible polymer layers.

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 &mgr;m, and that the filling material has a particle size in the range from 60 to 8000 &mgr;m and is contained in the plastics moulding in a proportion of approx. 30 to approx. 75 wt %.
