摘要:
The invention relates to a process for the manufacture of reinforced polyurethane foams based on the reaction of organic polyisocyanates and polyols in the presence of filler dispersions. These dispersions are prepared by in situ crushing of the filler in the polyisocyanate or polyol to a particle size of less than 7 microns.
