Abstract: PROBLEM TO BE SOLVED: To provide a low resilience flexible polyurethane foam that is excellent in laundering durability, solvent durability and the resistance to the discoloration by NO
X and the resistance to the discoloration by UV.
SOLUTION: The low resilience flexible polyurethane foam is produced by foaming a polyurethane raw material comprising a polyol component and an isocyanate, wherein the polyol component comprises two or more kinds of polyols having different molecular weights wherein the difference in molecular weight between a high molecular weight polyol having the highest molecular weight and a low molecular weight polyol having the lowest molecular weight is 500 or more; the polyurethane raw material comprises a monool; and the content of the isocyanate in the polyurethane raw material is 0.95-1.15 times the quantity of isocyanate-reactive equivalents relative to the total equivalents of the polyol component, the monool and water. Even if an excess of the isocyanate over the polyol component is used, an excessive crosslinking reaction is suppressed and the flexible polyurethane foam excellent in low resilience can be produced.

Abstract: PROBLEM TO BE SOLVED: To provide a car wiping material that efficiently cleans a car without a feeling of fatigue in wiping the car while causing no wiping unevenness nor smearing unevenness. SOLUTION: The car wiping material formed of a high water absorptive soft polyurethane foam is used. The elasticity of the soft polyurethane foam reduces the fatigue in wiping the car while absorbing and equalizing the variation of finger pressure to prevent wiping unevenness and smearing unevenness.

Abstract: PROBLEM TO BE SOLVED: To provide a hardly yellowing garment pad allowing to obtain sufficient yellowing resistance even in the case of using no special mixing component for yellowing prevention, such as antioxidant, ultraviolet absorber, and aliphatic isocyanate, and being foam with low hardness, and free from problems of deterioration and worsening of appearance caused by yellowing.
SOLUTION: This hardly yellowing garment pad is made of soft polyurethane foam of 15-35 cells/inch. The skeleton of the foam becomes thick by making the cells rough, and by that much, the surface area of the foam per unit volume reduces to decrease a discolored part (discolored area).
