Triethylene diamine (TEDA), also known by its CAS number 280-57-9, is a fundamental chemical intermediate and a vital catalyst in numerous industrial processes, most notably in the production of polyurethane (PU) foams. For businesses involved in PU manufacturing, understanding how to procure TEDA efficiently and cost-effectively is key. As a dedicated supplier of PU raw materials, we offer insights into the procurement process for B2B buyers.

What is Triethylene Diamine (TEDA)?

TEDA is a bicyclic tertiary amine characterized by its strong basicity and nucleophilicity. Its molecular structure, 1,4-diazabicyclo[2.2.2]octane, makes it a highly symmetrical and stable compound. In PU chemistry, TEDA (often formulated as part of mixtures like Amine Catalyst A33/A33LV) acts as a potent gelation catalyst, significantly promoting the reaction between polyols and isocyanates. This catalytic activity is essential for the rapid formation of the urethane polymer backbone, which gives PU foams their structural integrity and mechanical properties.

Key Considerations for Procuring TEDA:

  • Purity and Form: TEDA is typically available as a white crystalline solid or as part of liquid blends. For many industrial PU applications, liquid blends (like A33/A33LV) are preferred for ease of handling and accurate dosing. Ensure the purity and form meet your specific manufacturing requirements. When you buy Triethylene Diamine, always check the product specifications.
  • Catalytic Performance: The effectiveness of TEDA as a catalyst is well-documented. Its ability to accelerate the gelation reaction is critical for achieving desired cure times and foam properties in flexible, rigid, and semi-rigid PU foams, as well as in CASE applications.
  • Supplier Reliability: Establishing a reliable supply chain is crucial for continuous manufacturing. Partnering with an experienced Triethylene Diamine supplier who can guarantee consistent quality, timely delivery, and competitive Triethylene Diamine price is paramount.
  • Regulatory Compliance: Ensure that the TEDA you procure meets all relevant national and international regulatory standards for industrial chemicals.
