Abstract
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.
