Abstract
In order, in the case of a moulding composition for the production of sanitary-ware components, comprising a methyl-methacrylate-based syrup and from 50 to 85%, expressed in terms of the moulding composition, of an inorganic filler, to obtain an improvement in the scratch-proofness and the abrasion resistance of the shaped components which are obtained therefrom, it is proposed that the composition furthermore comprise elastomer particles or elastomer particle aggregates having a particle size <100 μm in an amount in the range of 5% by weight to <20% by weight, expressed in terms of the mass of the syrup.
