    • A polyurethane foam for vehicles is obtained by reaction, foaming, and curing of a polyurethane-foam raw material comprising polyol, polyisocyanate, a blowing agent, and a catalyst, and is used for vehicle parts. The foam raw material comprises expanded graphite and an inorganic compound hydrate. The polyol preferably comprises polymeric polyol in which a polyether polyol is graft-polymerized with a vinyl monomer, polyether polyol having a mass average molecular weight of from 400 to 1,000 in which a polyhydric alcohol is addition-polymerized with an alkylene oxide, and polyether polyol having a mass average molecular weight of from 2,000 to 4,000 in which a polyhydric alcohol is addition-polymerized with an alkylene oxide.

    • A polyurethane foam is obtained by reacting raw materials containing a polyisocyanate, a polyol, a water-absorbency-imparting agent, a catalyst, and a blowing agent, foaming the reaction mixture, and curing the foamed product. The polyol is a polyester polyol. The water-absorbency-imparting agent is a polyoxyalkylene compound having a molecular weight of 100 to 1000 and having a hydroxy group at an end of the molecular chain, or an alcohol with 1 to 8 carbon atoms. The amount of the water-absorbency-imparting agent is from 0.5 to 8 parts by mass per 100 parts by mass of the polyester polyol. The polyisocyanate is an aliphatic polyisocyanate, an alicyclic polyisocyanate, or an aromatic polyisocyanate in which the isocyanate groups are not directly attached to an aromatic ring. The foam has a water absorption ratio of 10 to 30 and a color difference ΔYI of 7 or less. The time required until water dropped onto a surface of the foam is completely absorbed into the foam is 20 seconds or less.
    • 通过使含有多异氰酸酯,多元醇,吸水性赋予剂,催化剂和发泡剂的原料反应,发泡该反应混合物,并使发泡产物固化,得到聚氨酯泡沫。 多元醇是聚酯多元醇。 吸水性赋予剂为分子链末端具有羟基或碳原子数为1〜8的醇的分子量为100〜1000的聚氧化烯化合物。 吸水性赋予剂的量相对于100质量份聚酯多元醇为0.5〜8质量份。 多异氰酸酯是脂肪族多异氰酸酯,脂环族多异氰酸酯或其中异氰酸酯基团不直接连接到芳香环上的芳族多异氰酸酯。 泡沫的吸水率为10〜30,色差ΔYI为7以下。 直到水落在泡沫表面上所需的时间被完全吸收到泡沫中是20秒或更短。
