Bis(2-dimethylaminoethyl) ether

Chemical properties

Colorless and transparent liquid or Brown liquid. Soluble in water, easily soluble in alcohol, benzene, etc.

The Uses of Bis(2-dimethylaminoethyl) ether

Bis(2-dimethylaminoethyl) ether is an efficient tertiary amine catalyst, which is suitable for the production of almost all foam products, mainly for the production of flexible foam products, especially for high resilience and RIM products. It is characterized by high catalytic activity, smooth foaming, large tolerance to tin, easy to adjust the formulation, and the physical and chemical properties of products produced with it, such as resilience and elongation, are better than other products.

What are the applications of Application

Bis(2-dimethylaminoethyl) Ether (Potassium Clavulanate EP Impurity M) is used in the manufacturing of flexible polyurethane foams.
