Hegrecat TEDA (Triethylene diamine) CAS:280-57-9

Appearance: Colorless to pale yellow liquid

Key Properties:

TEDA is a powerful and efficient catalyst. Its unique bicyclic structure endows it with high nucleophilicity. It can significantly accelerate the reaction between isocyanates and polyols, which is the key step in polyurethane synthesis. TEDA promotes both the gelation reaction, which forms the polymer network, and the blowing reaction that generates gas bubbles for foam formation. By carefully controlling the reaction rate, TEDA helps in creating a uniform and stable foam structure. It also plays a role in enhancing the cross - linking density of the polyurethane matrix, which in turn improves the mechanical properties of the final product, such as tensile strength, tear resistance, and compression resistance.

Applications

Polyurethane Foams:TEDA is extensively used in all types of polyurethane foams. In flexible slab stock and molded foams, like those used in furniture upholstery and mattresses, TEDA ensures the formation of foams with high flexibility, excellent resilience, and long - lasting comfort. For rigid polyurethane foams used in insulation applications, such as in building insulation panels and refrigerators, TEDA helps create a closed - cell structure with low thermal conductivity and high compressive strength, effectively maintaining temperature and structural integrity. In semi - flexible and elastomeric foams, TEDA contributes to achieving the desired balance of flexibility and strength, making them suitable for applications like automotive seating and gaskets.

Polyurethane Coatings:In polyurethane coatings, TEDA accelerates the curing process. It promotes the reaction between the resin components, leading to the formation of a hard, durable, and smooth coating film. Coatings cured with TEDA have good surface hardness, which can resist scratches and abrasion. They also exhibit excellent adhesion to various substrates, such as wood, metal, and plastic, ensuring long - term durability. Additionally, TEDA - catalyzed coatings show improved chemical resistance, protecting the coated surface from damage by water, solvents, and chemicals.

Other Polymer Applications: Beyond polyurethane, TEDA can be used as a catalyst in the production of epoxy resins, where it helps in the curing and cross - linking processes, enhancing the strength and performance of epoxy - based products. It also finds applications in certain polymerization reactions of other polymers, facilitating the formation of high - quality polymer materials with desired properties.

Our TEDA product is manufactured under strict quality control, ensuring a high purity level. It is a reliable choice for polyurethane manufacturers aiming to produce high - quality products with enhanced performance characteristics.
