How Does PMDETA Balance the Foaming and Gel Reactions in Rigid PU Foams?
Introduction to PU Reactions Making rigid polyurethane (PU) foam involves complex chemistry. Two main reactions happen at the exact same time. The first is the foaming reaction. The second is the gelling reaction. A catalyst like MXC-5 (Pentamethyldiethylenetriamine) controls both. It makes sure they happen at the right speed. The Foaming Reaction (Making Gas) The […]
