The polyurethane (PU) industry relies heavily on specialized chemical additives to achieve the desired properties in its diverse product range. Among these, catalysts are indispensable for controlling the complex polymerization reactions. Triethylene Diamine (TEDA), particularly in its TEDA-33 formulation, stands out as a highly effective and widely utilized amine catalyst. As a leading supplier and manufacturer of chemical intermediates, we are dedicated to providing the PU industry with high-quality TEDA-33, a vital component for producing superior polyurethane foams, coatings, and elastomers.

TEDA-33 is essentially a solution of triethylene diamine, often containing 33% of the active compound dissolved in dipropylene glycol. This specific formulation makes it an excellent 'gelling' catalyst, meaning it significantly accelerates the reaction between the isocyanate and polyol components. This reaction is the cornerstone of polyurethane formation, building the polymer network that gives PU its characteristic strength, flexibility, and insulating properties. The efficiency of TEDA-33 in promoting this gelation reaction is key to controlling the overall cure profile and the final physical characteristics of the PU product.

The versatility of TEDA-33 makes it a preferred choice across numerous PU applications. It is instrumental in the production of:

  • Flexible Polyurethane Foams: Essential for comfort applications like furniture cushioning, bedding, and automotive seating, where TEDA-33 helps achieve the desired balance of softness, resilience, and durability.
  • Rigid Polyurethane Foams: Critical for thermal insulation in buildings and appliances, TEDA-33 facilitates the formation of dense, closed-cell structures that provide excellent insulation values and structural rigidity.
  • Semi-Rigid Polyurethane Foams: Used in automotive interiors and other applications requiring a combination of flexibility and support.
  • Polyurethane Coatings and Elastomers: In these applications, TEDA-33 aids in faster curing, enhancing the durability, wear resistance, and chemical stability of the final product.
