Hegrecat PMDETA (Pentamethyldiethylenetriamine) CAS: 3030-47-5

Appearance: Colorless to pale yellow liquid

Key Properties:

PMDETA is a high - activity catalyst. It has a unique amine - based structure that endows it with the ability to effectively accelerate the reaction between isocyanates and polyols in polyurethane synthesis. It mainly catalyzes the foaming reaction, promoting the generation of gas bubbles during the reaction process. This results in the formation of a porous structure in polyurethane foams. At the same time, it also plays a role in balancing the overall foaming and gelation reactions. By adjusting the cross - linking density of the polyurethane network, PMDETA can influence the mechanical properties of the final product. For example, it can enhance the toughness and bearing capacity of polyurethane foams, making them more suitable for applications that require good shock absorption and load - bearing capabilities.

Applications

Polyurethane Soft Foams:PMDETA is widely used as a high - efficiency catalyst in the production of polyurethane soft foams. In the formulation of soft foam products, it significantly speeds up the foaming process. Based on 100 parts of polyether, adding 0.1 - 0.5 parts of PMDETA can achieve excellent results. The soft foams produced with PMDETA have high flexibility, good resilience, and can maintain their shape well under repeated use. These properties make them ideal for applications in furniture upholstery, mattresses, and automotive seating, providing users with comfortable cushioning.

Polyurethane Rigid Foams:Although mainly known for soft foam applications, PMDETA can also be used as an auxiliary catalyst in polyurethane rigid foam production. It helps improve the fluidity of large - capacity refrigerator PU foam. By promoting a more uniform distribution of materials during the foaming process, it contributes to the formation of a closed - cell structure with high thermal insulation properties. Rigid foams catalyzed by PMDETA are suitable for use in building insulation panels, refrigerators, and industrial cold storage facilities, effectively reducing heat transfer and energy consumption.

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

Other Applications:Beyond polyurethane, PMDETA can also be used in the synthesis of herbicides and insecticides. In the field of chemical reactions, its chelating ability allows it to form stable complexes with metal ions, which can be applied in certain metal - related processes. For example, it may be involved in metal - catalyzed reactions as a ligand to adjust the activity and selectivity of the metal catalyst.

Our PMDETA product is manufactured under strict quality control, ensuring a high purity of over 98%. It is a reliable choice for polyurethane manufacturers aiming to produce high - quality products with enhanced performance characteristics.
