Abstract

The present invention relates to melamine-formaldehyde foams comprising hollow microspheres wherein said hollow microspheres have a median particle diameter (D50, volume averaged, Malvern, Fraunhofer diffraction) in the range from 260 μm to 490 μm, and also processes for producing these melamine-formaldehyde foams and their uses.
