。Examples N1 to 12 and Comparative Example 1 Rigid polyurethane foams were obtained using the components listed in Table 1. That is, first, a compounded solution shown in Table 1 was prepared, and this was rapidly mixed with crude dimethane diisocyanate.
A rigid polyurethane foam was produced by immediately pouring into a vertical mold with dimensions 200 x 200 x 1501 and allowing free expansion. The characteristics of the obtained 7 ohms are shown in Table 1. Dimensional stability was determined by measuring the dimensional change rate when stored at 25°C for 48 hours. However, the measurement direction is perpendicular to the foaming direction. In addition, the details of each component in the table are as follows.
