A process for making acrylic sheets which contain mineral fillers and which can be thermoformed into integral top vanity tops or sinks. The sheets and thermoformed products thereof have a matte finish surface and appearance that does not require additional finishing steps such as sanding to create a uniform appearance. The sheets and thermoformed products possess good stain resistance, as measured by existing industry standards.
L'invention porte sur un procédé de production de feuilles acryliques contenant des matières de charge minérale et pouvant être thermoformées en tables de toilette ou éviers d'une seule pièce. Les feuilles et les produits thermoformés qui en sont issus ont une surface au fini non lustré et, de par leur aspect, n'exigent pas de travaux de finition supplémentaire, tel qu'un sablage leur conférant une certaine uniformité. Les feuilles et les produits thermoformés résistent bien aux salissures et ce, au regard des normes en vigueur dans l'industrie.
