Tetramethylimidazolidinediylpropylamine (TMBPA) as a Dual-Function Catalyst for Flexible and Rigid Foams

Tetramethylimidazolidinediylpropylamine (TMBPA): A Dual-Function Catalyst for Flexible and Rigid Foams Introduction Polyurethane (PU) foams, renowned for their versatility and diverse applications, are produced by the exothermic reaction of polyols and isocyanates in the presence of catalysts, blowing agents, surfactants, and other additives. The catalysts play a crucial role in controlling the two main competing reactions:…
