Beschreibung
Zusammenfassung:	The invention relates to polyurethane foams which are used, for example, to produce moulded articles, such as soles for different types of shoes. More specifically, the invention relates to a low-density polyurethane foam having mechanical properties which are suitable for shoe soles and, in particular, for sports shoe soles. The inventive foams are produced by causing a reaction between a diisocyanate prepolymer and a polyester polyol comprising an inorganic filler in suspension. Moreover, the density of said foams is of the order of 0.2 g/cm .
