The Intricate Balance: Optimizing Blow-Gel Reactions in Polyurethane Foam with Amine Catalysts Abstract: Polyurethane (PU) foam synthesis involves a delicate balance between two competing reactions: the polyol-isocyanate reaction (gelation) and the water-isocyanate reaction (blowing). This balance dictates the final foam properties, including cell size, density, and structural integrity. Amine catalysts play a pivotal role in...
