Triethylenediamine

China quality Triethylenediamine (TEDA) from Polykem factory, also known as DABCO (1,4-Diazabicyclo[2.2.2]octane), is a bicyclic tertiary amine with CAS number 280-57-9. It is widely recognized as a high-efficiency catalyst in polyurethane chemistry and is also used as a curing accelerator, pharmaceutical intermediate and electronic materials additive. TEDA is available as white crystalline powder and as a 33% solution in dipropylene glycol (DPG).

Polykem supplies high-quality TEDA products under an ISO-certified quality management system, with packaging options including 25kg cardboard drums and 500kg container bags. Produced through the ethanolamine process, Polykem can offer industrial grade TEDA (≥99%), electronic grade TEDA (≥99.9%) and solution type TEDA, such as 33% TEDA in DPG. Customized solution formulation services are also available according to customer application requirements.

Key Performance Features

Triethylenediamine is valued for its strong catalytic activity, stable quality and flexible application forms. In polyurethane systems, TEDA primarily promotes the isocyanate-polyol reaction (gel reaction), helping build the polymer network and improve reaction efficiency and processing stability. It is commonly used as a standard gel catalyst in both rigid and flexible foam formulations, often combined with blowing catalysts to balance foam processing.

Polykem supplies TEDA in industrial grade, electronic grade and solution type to meet different production requirements. Solid TEDA is suitable for customers with standard storage and dosing systems, while the 33% TEDA solution in DPG reduces sublimation and handling concerns associated with pure crystalline powder, making it easier to dose accurately on production lines.

Key product features include:

Applications of TEDA

Triethylenediamine (TEDA) is mainly used as a polyurethane catalyst, especially in PU foam production. It can also be used in resin curing, pharmaceutical synthesis and electronic material processing where stable catalytic performance is required.

PU Foam Catalyst

TEDA is widely used as a gel catalyst in flexible PU foam, rigid PU foam and molded foam systems. It helps promote the reaction between isocyanates and polyols, supporting foam structure control and stable production performance.

Polyurethane Elastomers, Coatings and Adhesives

In polyurethane elastomers, coatings and adhesive systems, TEDA can support curing reaction control and improve processing efficiency. It is suitable for formulations that require a high-efficiency tertiary amine catalyst.

Epoxy Resin Curing Accelerator

TEDA can be used as a curing accelerator in selected epoxy resin systems. It helps promote curing reactions and is suitable for industrial coating, adhesive and composite material applications.

Pharmaceutical Intermediate and Synthesis Catalyst

TEDA is also used as a pharmaceutical intermediate and catalyst in certain organic synthesis processes. For these applications, customers usually pay more attention to purity, impurity control and documentation support.

Electronic Materials Additive

Electronic grade TEDA can be used in electronic material applications where higher purity and more stable quality are required. Polykem can supply electronic grade TEDA according to customer technical requirements.
