Let’s talk about the pore opening agent in polyurethane foam

First of all, why do we use pore opening agents? PolyurethaneFoam glueforming bubblesThe process involves foaming and gelation reactions at the same time, especially MDI system foaming. Since the gelation rate is higher than the foaming rate, the reaction The generated gas is easily trapped in the cell structure, that is, the porosity is insufficient,…
