Pentamethyldiethylenetriamine is the material that helps to make polyurethane foam

For industrial chemical raw materials, people who are not usually engaged in related work may not be familiar with it. But don't underestimate it, it is an important raw material that is widely used in the chemical industry, and the chemical products produced by it are closely related to our life. What is pentamethylenediethylenetriamine today?

In fact, it is a colorless or light yellow transparent liquid that can directly dissolve in water, ether, alcohols and other substances, and is quite strong in absorbing carbon dioxide and water that are free in the air, so it should be stored under seal. As a product of the chemical reaction of triethylenediamine, it is usually used to help catalyze polyurethane reactions. So how does it work?

First of all, pentamethylenediethylenetriamine and DMCHA are a good "partner", they often "work together" to improve the process technology, improve the quality of the role of production are more prominent. The brightest is "polyurethane rigid foam, polyisocyanurate sheet rigid foam" and other formulations, can achieve good foaming effect. Because the foam produced by the flow is very good, which means that the surface cavity distribution of the board will be more uniform, small, the material as a whole more stable, viscosity will also become lower, even in cold climates, there will be no dust and debris.

Secondly, it is the role of fast catalytic foam breaking. For example, in the use of polyether polyurethane soft block foam or molded foam, the appropriate dose ratio is 70%, because at this time the activity of the catalyst can play a better effect, so the foaming speed becomes faster, the product obtained toughness is higher, and good toughness can achieve better load-bearing performance, and can not be deformed for a long time, as one of the raw materials such as sofa mattress, can make it more soft and comfortable and durable, is deeply Furniture industry favorite one of the chemical raw materials.

Third, it is the role of soft foam delayed catalysis. It can be used as a chemical raw material to delay the time of foam opalescence. For example, in the production of complex shape of the foaming process, it can effectively improve the structure of the bubble pore, the quality obtained after molding can be significantly improved. If the dosage is appropriately increased, the foam rise rate will be greatly reduced, thus achieving a shorter curing time. Help enterprises to improve production efficiency, which also means the reduction of manufacturers' costs.

Therefore, pentamethyldiethylenetriamine is an indispensable industrial chemical raw material in the modern production process of industrial chemistry.
