PMDETA catalyst is a highly active, pure liquid tertiary amine that is suitable for use as a blowing catalyst in a number of rigid and flexible polyurethane foam applications. ADVANTAGES: In model systems, PMDETA catalyst has proven to have catalytic activity equivalent to other established blowing catalysts for the urea reaction. However, PMDETA catalyst has a greater affect than established blowing catalysts on the urethane or gelling reaction. PMDETA catalyst is very effective in pour-inplace polyurethane systems (such as rigid appliance systems), which are based on MDI. At a use level of 1.5 php, PMDETA catalyst provides the necessary flowability and cure rates required in the production environment. PMDETA catalyst is also recommended for TDI, TDI/MDI and MDI HR flexible molded foams, as well as for use in integral skin and microcellular systems. It can also be as a raw material to make quaternary ammonium salt.
