Composite tertiary amine catalyst SA-800: an innovator in polyurethane foaming process

In the chemical industry, there is a magical existence, which is like an unknown behind-the-scenes director, controlling the rhythm and effect of the entire stage. This existence is the catalyst, and the composite tertiary amine catalyst SA-800 is the best among them. Today, let’s unveil the mystery of this “hero behind the scenes” and see how it shows off its strength in the polyurethane foaming process.

What is the composite tertiary amine catalyst SA-800?

Definition and Function

Composite tertiary amine catalyst SA-800 is a highly efficient catalyst designed for polyurethane foaming process. Its main responsibility is to accelerate the reaction between isocyanate (MDI or TDI) and polyols while promoting the formation of carbon dioxide during foaming. Factually speaking, it is like a hypnotist, allowing the ingredients to quickly enter “sleep”, thus forming the foam structure we need.

Application Fields

SA-800 is widely used in the production of soft, semi-rigid and rigid polyurethane foam. Whether it is the sofa mattress, car seats, or even cold storage insulation boards at home, it is available. It can be said that our daily life cannot be separated from this small catalyst.

Product parameters of SA-800

To understand a product, you must first start with its parameters. Here are some key indicators of SA-800:

parameter name	Value Range
Appearance	Slight yellow to amber transparent liquid
Density (25°C)	1.05-1.15 g/cm³
Viscosity (25°C)	30-70 mPa·s
Moisture content	?0.5%

These parameters not only determine the physical characteristics of SA-800, but also affect their performance in practical applications.

Process Advantages

Improve the reaction efficiency

Using SA-800 can significantly improve the reaction efficiency of polyurethane foaming. Compared to traditional single catalysts, it can be distributed more evenly in the reaction system, ensuring that every corner is fully catalyzed. It’s like arranging more supply stations for a marathon so that the runners (i.e. reactants) can continue to exert force and not fall behind.

Improve foam quality

SA-800 can also effectively improve the quality of foam. It can control the size and distribution of bubbles, making the final product more delicate and uniform. Imagine that a cup of fragrant coffee lace can hardly present a beautiful pattern without precise control. Likewise, without a good catalyst, the foam can become rough.

Status of domestic and foreign research

Domestic Research

In recent years, domestic research on composite tertiary amine catalysts has become increasingly in-depth. For example, a study from a university’s School of Chemical Engineering showed that by optimizing the SA-800 synthesis process, its catalytic performance can be further improved. The researchers adopted a new synthesis route, reducing the generation of by-products and improving the purity of the product.

Foreign News

Related research is also active abroad. Scientists from a well-known American chemical company have found that by adjusting the proportion of different components in SA-800, customized catalysis of specific types of foam can be achieved. This research result provides new ideas for the development of personalized polyurethane products.

Conclusion

Composite tertiary amine catalyst SA-800 is undoubtedly a pearl in the polyurethane foaming process. It drives technological advancement in the industry with its outstanding performance and wide applicability. In the future, with the continuous advancement of technology, I believe that the SA-800 will have more surprising performances. Let us look forward to this “behind the scenes hero” writing more legendary stories in the polyurethane world!
