| titleOfInvention | Method for producing polyurethane foam with high air permeability and low resilience |
| abstract | The invention provides a viscoelastically flexible polyurethane foam having excellent viscoelastic performance useful as a vibration, sound or impact absorber or as a mattress, pillow, cushion, or the like, capable of more uniformly dispersing human body pressure than conventional flexible polyurethane foam, thus effective in reducing sense of fatigue and bedsore, therefore excellent in terms of human engineering. The flexible polyurethane foam is provided, comprising carrying out a reaction between a polyisocyanate(A), a polyol(B), a foaming agent(C), a catalyst(D) and a foam stabilizer(E),wherein, the polyol(B) comprises (b1) a polyester polyol with an average functional group number of 2.5-4.5 and a hydroxy equivalent of 300-500 and (b2) a polyalkylene polyol with an average functional group number of 2.5 and a hydroxy equivalent of 500-3,000 in a specific proportion. The isocyanate index of this flexible polyurethane foam is 50-100. |
