Abstract

PURPOSE: An active hydrogen-bearing compound and an isocyanate are foamed by the use of a fluorocarbon containing an organotin compound as a foaming agent to produce urethane foams with high dimensional stability, low thermal conductivity and fine-sized foams in high efficiency.
CONSTITUTION: (A) An active hydrogen-bearing compound (polyether) containing water is mixed with, e.g., a catalyst, a foaming regulator, or foaming agent. This component is simultaneously combined with (B) an isocyanate and a foaming agent of fluorocarbon containing an organotin compound as a catalyst such as dichlorodifluoromethane to effect foaming.
