"Polyester Polyol, Composition For Polyurethane, Composition For Polyurethane Foam, Polyurethane Resin, And Polyurethane Foam"
Abstract: The present invention provides a polyester polyol, preferably a plant-derived polyester polyol, suitable for a composition for polyurethane foam that contributes to the reduction of load on the environment and has a good balance of high resilience, moderate hardness, and high durability as a cushioning material for vehicle seat cushions. A polyester polyol having a hydroxyl value in the range of 15 to 100 mgKOH/g according to the present invention is produced by a condensation of raw materials comprising 'at least one selected from the group consisting of fatty acids having a hydroxy group and fatty acid esters having a hydroxy group with a polyhydric alcohol having an average number of functional groups of more than three but not more than eight. The raw materials contain 90% to 100% by mass of a fatty acid having a hydroxy group and a fatty acid ester having a hydroxy group in total.
