Abstract

With an integral, board-like component, in particular for use as a kitchen working surface, comprising a visible side and a rear side, wherein the visible side comprises a layer consisting of a polymer matrix filled with a first, inorganic filler, its specific density being greater than the specific density of the polymer matrix, it is suggested for the production of the boards in a simple manner and with a good planarity that the filler content of the first filler in the visible side layer be 50 to 90% by volume, that the rear side comprise a layer which is formed from a polymer matrix filled with a second inorganic filler, wherein the proportion of the polymer matrix in this layer in % by volume differs quantitatively by 20% at the most from the volume content of the polymer matrix in the visible side layer and wherein the specific density of the second filler is .ltoreq.0.6 g/cm.sup.3.
