초록

This invention relates to a process for the production of cold-setting flexible polyurethane foam useful for damping sound comprising reacting a polyisocyanate in the presence of water with (a) at least one polyether having an OH number of from 20 to 60 and containing at least two OH groups, wherein said polyether is based on 75 to 95% by weight propylene oxide and 5 to 25% by weight ethylene oxide; (b) a polyether or polyester having an OH number of from 150 to 400 and containing at least two OH groups; and (c) a polyether different from components (a) ...
