N,N,N′,N″,N″-Pentamethyldiethylenetriamine, commonly abbreviated as PMDETA and identified by CAS number 3030-47-5, is a synthetic organic compound that holds significant importance across various industrial sectors, particularly in polyurethane chemistry. As a leading manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. is well-versed in the chemical properties and extensive applications of PMDETA.

Chemically, PMDETA is a tertiary amine with the molecular formula C9H23N3 and a molecular weight of approximately 173.30 g/mol. It is characterized by its structure, which includes multiple dimethylamino groups. This molecular architecture contributes to its effectiveness as a catalyst. PMDETA typically presents as a colorless to pale yellow transparent liquid, with a density around 0.827-0.830 g/cm³ at 25°C. Its relatively low water content (often below 0.50%) and specific boiling point (around 198°C) are crucial for its performance and handling in industrial processes.

The primary industrial application for PMDETA is as a high-activity catalyst in the production of polyurethane (PU) foams. Its tertiary amine nature makes it an excellent accelerator for the reaction between polyols and isocyanates, driving both the blowing reaction (gas formation) and the gelling reaction (polymer cross-linking). This dual functionality makes it highly valuable for producing a wide range of PU products.

In rigid PU foams, PMDETA is especially prized as a blowing catalyst. It efficiently catalyzes the reaction of isocyanate with water, generating carbon dioxide gas that creates the foam’s cellular structure. This is critical for insulation applications, such as in PIR (Polyisocyanurate) panels for construction, refrigerators, and appliances, where fine cell morphology and excellent thermal insulation are paramount. Manufacturers looking to purchase catalysts for insulation materials will find PMDETA to be a highly effective option.

Beyond rigid foams, PMDETA also finds utility in flexible PU foams, contributing to the control of the gelling process to achieve desired mechanical properties like flexibility and resilience. It can also be utilized as an intermediate in the synthesis of other chemicals, including quaternary ammonium salts, which have diverse applications as surfactants and disinfectants.
