    摘要: Moulding composition, comprising, in each case based on the total weight of the moulding composition,A) from 83% by weight to 99.5% by weight of a polymer matrix which is composed of at least one (meth)acrylimide (co)polymer,B) from 0.5% by weight to 17.0% by weight of ceramic beads,where the melt volume index MVR of the moulding composition, measured to ISO 1133 at 260° C. using 10 kg, is from 1.0 cm3/10 min to 20.0 cm3/10 min.The moulding composition can be used for production of mouldings with a velvet-matt and preferably rough surface. These mouldings are particularly suitable as parts of household devices, of communications devices, of hobby equipment or of sports equipment, or as bodywork parts or parts of bodywork parts in automobile construction, shipbuilding or aircraft construction, or as parts for illuminants, signs or symbols, retail outlets or cosmetics counters, containers, household-decoration items or office-decoration items, furniture applications, shower doors and office doors, or else as parts in the construction industry, as walls, as window frames, bench seats, lamp covers, diffuser sheets, or for automobile glazing.
