Abstract

[PROBLEMS] To provide a flexible polyurethane foam which has excellent storage stability and is excellent in both air permeability and the feeling of bottoming out which are incompatible with each other. [MEANS FOR SOLVING PROBLEMS] A polyisocyanate composition for flexible polyurethane foam which is obtained by conducting urethane formation reaction of pure MDI (i) with a polyol (ii) in an at most equimolar amount and mixing the obtained product with polymeric MDI (iii) with the following requirements satisfied: (2,2'-MDI + 2,4'-MDI)/MDI = 60 to 90% by mass MDI/((i) + (iii)) = 50 to 90% by mass (ii-1) : (ii-2) = 20 to 40% by mass : 80 to 60% by mass with the proviso that (ii-1) is polyether polyol having Mn of 1,000 to 10,000, an average functionality of 2 to 8, and an oxyethylene repeating unit content of 70% by mole or above, and (ii-2) is polyether polyol having Mn of 1,000 to 10,000, an average functionality of 2 to 8, and an oxypropylene repeating unit content of 80% by mole or above.
