Heat cycling crack-resistant, granite-simulating sinks, basins etc

摘要

A plastic moulded body, in particular a kitchen sink, a washing basin or table top or the like, comprises a polymer phase composed of a curable reaction mass and of a particulate filling material incorporated therein which comprises a resinous material filled with an inorganic filler. In order to achieve a good resistance against water whitening and cracking in the hot-cold cycle, the polymer phase contains up to 5 wt. % inorganic additive particles, in relation to the plastic moulded body, and the particulate filler can swell in the curable reaction mass. The filled resinous material contains 50 to 80 wt. % inorganic filler with an average grain size of about 5 to about 100 mu m, and the filler has a grain size in a range from 60 to 8000 mu m and makes up about 30 to 75 wt. % of the plastic moulded body.
