Abstract
In order to provide a moulding composition which makes it possible to form shaped components having not only one but two or more visible sides, it is proposed that this composition comprise a methyl-methacrylate-based syrup and up to 85%, expressed in terms of the moulding composition, of an inorganic filler, and that the moulding composition comprise deformable, propellant-filled hollow microspheres having a plastic wall which is essentially insoluble in methyl methacrylate, the proportion by volume of the hollow microspheres to the total volume of the moulding composition being in the 5 to 50 vol. % range.

Moulding composition for the production of sanitary-ware components, comprising a methyl-methacrylate-based syrup and up to 85% by weight, expressed in terms of the moulding composition, of an inorganic filler, wherein the moulding composition comprises compressible, propellant-filled hollow microspheres having a plastic wall which is essentially insoluble in methyl methacrylate and which allows said microspheres to remain unbroken in said moulding composition during moulding so as to provide shrinkage compensation, the proportion by volume of the hollow microspheres to the total volume of the moulding composition being in the 5 to 50 vol. % range.
