Urethane foam and its manufacturing method |
| abstract |
(57) [Problem] To provide a urethane foam capable of reducing a deflection difference in a load deflection curve and lowering a resonance frequency as compared with a conventional cold-cured polyurethane foam. SOLUTION: A raw material of a cold cure urethane foam mainly composed of a polyol and an isocyanate component is used as a foam stabilizer and has a perfluoroalkyl group structure. The surface tension of the aqueous solution when 1% is added is 13 to 40 (dyne) / Cm25 ° C), and the cell obtained by adding a fluorine-based surfactant having a surface tension of 25 (dyne / cm25 ° C) or less at the time of addition of 0.1% of the toluene solution and foaming the resulting mixture is coarse and irregular. It is urethane foam. |
