<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an foamed urethane sheet which can manufacture a soft foamed urethane sheet having low density and a high foaming ratio with favorable thickness accuracy even if the foamed urethane sheet has a thin thickness. <P>SOLUTION: The method for manufacturing the foamed urethane sheet comprises steps for: applying a composition containing a urethane prepolymer having an NCO group at the terminal of the molecule thereof to a base to form a sheet-like coating film 2; bringing the coating film into contact with a perforated mold-release base 1; and exposing the coating film 2 to water vapor while making the perforated mold-release base 1 contact with the coating film to foam and cure the coating film 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
