ABSTRACT:
In a method of manufacturing sheets of highly wear-resistant plastics material, particularly for manufacturing covers subjected to wear, such as, for example, belts, straps, shoe soles or the like, the behavior of the sheets, particularly as far as suppleness, wear-resistance and inexpensiveness in the production are concerned, is to be significantly improved over known sheets of leather or rubber. The blanks manufactured from such sheets are to have the same properties. According to the invention, sheets are manufactured in a high-pressure casting method from a mixture of polyol and a filter portion of up to 30% with the addition of isocyanate, chalk being particularly used as filler.
