Abstract:
The object of the invention is a method for producing polyurethane and/or polyisocyanurate insulating foam based on foaming reaction mixtures containing polyisocyanates, compounds having reactive hydrogen atoms, propellants, stabilizers, nucleation agents, and optionally further additives, which is characterized in that porous solids, in particular silicates having a zeolite structure, are used as the nucleation agents.
