PMDETA

PMDETA is a highly efficient amine-based gel catalyst widely used in rigid polyurethane (Rigid PU) systems. With its chemical name Pentamethyl Diethylenetriamine, it optimizes cell stability and foam quality by controlling especially the gel phase in polyurethane reactions.

This catalyst regulates the polyol-isocyanate interaction and ensures the formation of a smooth and closed cell structure. Thus, the thermal insulation performance of rigid foams increases, their mechanical strength becomes stronger and the surface quality improves. PMDETA stands out with its balanced reaction speed and wide processing tolerance, especially in polyisocyanurate (PIR) and rigid spray foam applications.

PMDETA allows fine-tuning of the reaction profile when used in combination with other amine and tin catalysts. This allows manufacturers to precisely control curing time, foam density and cell structure.

PMDETA catalyst supplied by Areks Kimya is a reliable choice in rigid polyurethane systems with its high purity level, stable performance and environmentally friendly formulation compatibility.
