Introduction N,N-Dimethylcyclohexylamine (DMCHA), represented by the chemical formula C8H17N, is a tertiary amine catalyst widely employed in the production of rigid polyurethane (PUR) foams. Its efficacy stems from its ability to accelerate both the urethane (polyol-isocyanate) and blowing (isocyanate-water) reactions, thereby influencing the foam’s cell structure, density, and overall mechanical properties. This article provides a...
