Enhancing Foam Uniformity with Tetramethylimidazolidinediylpropylamine (TMBPA) in High-Pressure Molding 💡 Introduction Tetramethylimidazolidinediylpropylamine (TMBPA), a tertiary amine catalyst, plays a crucial role in the high-pressure molding of polyurethane (PU) foams. Its unique chemical structure and catalytic activity make it particularly effective in promoting both the gelling (polyol-isocyanate reaction) and blowing (water-isocyanate reaction) reactions, leading to improved...
