Composition, method for producing said composition, urethane resin, and cooling component and article provided with said urethane resin

Abstract

The present invention aims to provide a composition that gives, as a reaction product, a urethane resin having excellent heat dissipation ability and excellent flexibility. The composition of the present invention contains a polyol (A), a polyisocyanate (B), and an inorganic filler (C), wherein the polyol (A) contains a polyol (A1) having at least three hydroxy groups in one molecule, an isocyanate index of the polyisocyanate (B) based on the polyol (A) is 0.20 to 0.77, the isocyanate index being a ratio of a total mole number of isocyanate groups of the polyisocyanate (B) in the composition to a total mole number of hydroxy groups of the polyol (A) in the composition, and a weight percent of the inorganic filler (C) is 70 to 97 wt % based on the weight of the composition.
