Abstract:
A flame-retardant rigid polyurethane foam contains a flame retardant, the foam having a ratio of the maximum peak intensity ratio (P1) of the foam after moist heat treatment of the foam for one week at a temperature of 80° C. and a humidity of 85% to the maximum peak intensity ratio (P2) of the foam before this moist heat treatment of 85% or more (P1/P2×100). The P1 and P2 each refer to the ratio of the maximum peak intensity of 1390 to 1430 cm −1  to the maximum peak intensity of 1500 to 1520 cm −1  when the infrared absorption spectrum is measured at a position 5 to 10 mm from the surface of the foam, and the average intensity of 1900 to 2000 cm −1  is adjusted to zero.

Claim (Index 3):
The flame-retardant rigid polyurethane foam according to  claim 1 , comprising\n a trimerization catalyst and a catalyst other than the trimerization catalyst, the trimerization catalyst being present in an amount of 0.6 to 10 parts by weight per 100 parts by weight of a urethane resin, the catalyst other than the trimerization catalyst being present in an amount of 3 parts by weight or less per 100 parts by weight of the urethane resin.
