も短縮されず、高速成形を行うにも限度かあった。However, when the amount of tertiary amine catalyst added is increased, the fluidity of the raw acid deteriorates, resulting in molding defects, or it becomes necessary to pour the raw material into the mold and then demold the molded product. The time required to mold (hereinafter referred to as demolding time)
However, the length could not be shortened, and there were limits to high-speed molding.
また、イソ／アネートを全てＭＤＩ系にした場合には、

On the other hand, if the upper limit is exceeded, kelp formation will occur too quickly and foaming will not occur sufficiently. As a result, the functionality of the molded foam may be impaired. From this point of view, it is desirable to add each additive within the "secondary" range.
