<p>The disclosure relates to self-reinforced, thermoplastically mouldable sheets made from poly(meth)acrylate. The sheets have at least two layers which differ in their filler content, where the filler content is the percentage proportion by weight of the reinforcing fillers based on the total weight (% by weight) of the respective layer. The ratio between the elongation at break of the layer with higher filler content and the elongation at break of the layer with lower filler content is less than 1.5, advantageously from 0.8 to 0.1, the elongation at break for the respective layer being determined to DIN EN ISO 527-2. The poly(meth)acrylate sheets of the invention serve as a semifinished product, in particular for producing sanitary items, such as bathtubs, shower trays or washbasins, preferably by thermoforming. Sanitary items thermoformed from the sheets fulfil all of the requirements of the relevant standards for sanitary items, namely in particular DIN EN 198, DIN ISO 178 and 179, and also DIN ISO 4624, without the need for any other reinforcing layers sprayed on or otherwise applied after moulding.</p> |
