摘要： The mixing system includes a first container filled with a polyol composition, a second container filled with an isocyanate composition, and a stationary mixer configured to mix the polyol composition discharged from the first container and the isocyanate composition discharged from the second container. The polyol composition includes a polyol, a catalyst, and a low boiling point compound having a boiling point of less than 0° C. The isocyanate composition includes an isocyanate compound and a low boiling point compound having a boiling point of less than 0° C. The first container and the second container each have an internal pressure in a range of 0.3 to 1.0 MPa at 35° C., and a mixer portion of the stationary mixer has a length of 30 to 230 mm. A mixing system can be provided that enhances the mixability of a polyol composition and a polyisocyanate composition in a stationary mixer and prevents curing in the stationary mixer.
