Abstract (en)
[origin: WO2021165149A1] The invention relates to a method for producing PU foams, in particular PU rigid foams, on the basis of foamable reaction mixtures containing polyisocyanates, compounds with reactive hydrogen atoms, blowing agents, foam stabilisers, and optionally further additives. According to the invention, additional polymer particles are used, the average particle size of the polymer particles being < 100 µm, preferably < 70 µm, in particular 5 to 50µm.
