Abstract: PROBLEM TO BE SOLVED: To obtain the subject foam having a reduced thermal conductivity by reacting a (modified) organic polyisocyanate with a polyhydroxyl compound, an H-functional low-molecular-weight chain extender or crosslinking agent, a blowing agent, and a catalyst in the presence of additives. SOLUTION: A rigid foam having a thermal conductivity of 0.018 W/mK or below is obtained by reacting (A) a (modified) organic polyisocyanate with (B) a polyhydroxyl compound having at least two reactive hydrogen atoms, a functionality of 2-8, and a molecular weight of 400-6,000 and represented by the formula, (e.g. a polyether polyol), 0-20 wt.%, based on component B, H-functional low-molecular-weight chain extender or crosslinking agent such as ethanolamine, a blowing agent such as cyclopentane, 0.001-5 wt.%, based on component B, catalyst such as tin laurate in the presence of additives such as a filler. In the formula, R is hydrogen, methyl, ethyl, or a 3-6C alkyl; R' is hydrogen, methyl, benzyl, or the like; (n) is 0-4; (m) is 1-3; (o) is 1-3; and X is an n-alkyl, an aralkyl, or the like.
