摘要：
Disclosed herein is a method for producing polyurethane or polyisocyanurate foams. The method involves reacting a composition (Z1) with at least one polyisocyanate, and occurs in the presence of at least one nucleating agent and a blowing agent, in which the nucleating agent and the blowing agent are mixed to obtain a composition (Z2) that is added to the composition (Z1) before it is reacted with the at least one polyisocyanate. The composition (Z1) contains (i) 100 parts by mass of a composition (ZP) including at least one polyol and at least one catalyst that catalyzes formation of a urethane, urea or isocyanuarate bond, and (ii) from 0.05 to 10 parts by mass of a surfactant TD having an HLB value below 6 and no silicon atom.
