July 4, 2023by admin0


Dabco NMM is a tertiary amine-based foaming catalyst that facilitates urea (water-isocyanate) reactions in a variety of hard and soft polyurethane foam applications. It is the industry standard foaming catalyst for soft foams and is used in TDI-based soft foam systems such as mattresses, seats and automobiles. It is also used in combination with trimer catalysts in PIR laminated paperboard formulations. Dabco NMM can also be used in MDI, TDI/MDI, MDI High Resilience (HR) soft molding foams as well as self-crusting and microcellular systems. It has a shelf life of 36 months.


The CAS number of the Dabco NMM is 109-02-4. This is a unique identifier for Dabco NMM that is used to track and identify it throughout the supply chain. The CAS number is also used to search databases and other resources for information about Dabco NMM.


Dabco NMM is also known as N-methylmorpholine.
