A method for the production of expanded polymeric materials, in particular for producing thermally insulating materials used in refrigerators and the like. Comprises a mixture of reagents based on isocyanate and polyol with the addition of expandable polystyrene-based microspheres, in which method the ratio by weight between the reagents and the above-stated expandable microspheres is between 7:1 and 1:2 |
