摘要：
The present invention provides a polyurethane foam for an automobile steering wheel. More particularly, the present invention relates to polyurethane foam formed by using a predetermined amount of a polyol having various functional groups and OH values and a predetermined amount of isocyanate having a certain function, along with water as a foaming agent, thereby preventing the environmental problems caused by use of the conventional fluorine-based or pentane-based foaming agent and also improving durability such as water resistance.
