| description | The present invention relates to polyurethane foams used especially for manufacturing moulded articles such as soles for various types of shoe. The invention relates more particularly to a low-density polyurethane foam whose mechanical properties are suitable for use as shoe soles and even more particularly for sports shoe soles. These foams are obtained by reaction between a diisocyanate prepolymer and a polyesterpolyol comprising, in suspension, a mineral filler. The foams of the invention have a density of about 0.2 g/cm3. |
