Term amine polyurethane catalyst BL-17: Ideal for complex formulas

In the vast world of the chemical industry, there is a magical existence – the tertiary amine polyurethane catalyst BL-17. It is like a skilled chef who is easy to ease in the complex world of formulas, cleverly combining various ingredients to create amazing products. Today, let’s explore the charm of this “Chemist” in depth.

What is tertiary amine polyurethane catalyst BL-17?

Term amine polyurethane catalyst BL-17 is a chemical substance specially used to accelerate and control polyurethane reactions. It is like a commander, able to effectively direct the chemical reaction between isocyanate and polyol, ensuring the product has ideal physical and mechanical properties. BL-17 is highly regarded for its efficient catalytic capability, wide applicability and good stability.

The basic principles of catalyst

How the catalyst works can be explained in one metaphor: Imagine that you are climbing a steep mountain, and it is very difficult and time-consuming to climb directly. However, if there is a path around a steep part, although the distance may be a little longer, it is much easier overall. The function of the catalyst is to open up such a “small path” for chemical reactions, lower the energy threshold required for the reaction, and make the reaction proceed faster and more efficiently.

BL-17 application fields

BL-17 is widely used in a variety of fields, including but not limited to:

Foaming: Used to make soft and hard foams such as mattresses, seat cushions and thermal insulation.
Coating: Improves the adhesion and durability of the coating.
Odulant: Enhance the bonding strength and temperature resistance.
Elastomer: Improves the elasticity and wear resistance of the product.

Product Parameters

To understand a catalyst, we first need to know its basic parameters. Here are some key features of BL-17:

parameter name	Description
Appearance	Transparent Liquid
Density (g/cm³)	0.95 – 1.05
Active ingredient content	?98%
Viscosity (mPa·s)	20 – 40 (25°C)
pH value	7.5 – 8.5

These parameters not only determine the performance of BL-17 in different environments, but also affect its compatibility with other chemicals.

References of domestic and foreign literature

In order to better understand the functions and applications of BL-17, we can refer to some relevant documents at home and abroad. For example, a study by the American Chemical Society (ACS) pointed out that the catalytic efficiency of BL-17 at low temperatures is significantly higher than that of other similar products. A study by the Chinese Chemical Society shows that by optimizing the dosage of BL-17, the closed cell rate and compressive strength of polyurethane foam can be effectively improved.

Using tips and precautions

Although the BL-17 is powerful, some details need to be paid attention to during use to ensure good results.

Precise Metering: Too much or too little catalyst will affect the quality of the final product. It is recommended to accurately control the dosage according to the specific formula requirements.
Storage conditions: It should be stored in a cool and dry place to avoid direct sunlight and high temperature environments.
Mixing order: The correct mixing order can prevent side reactions from occurring and ensure the smooth progress of the reaction.

Conclusion

Term amine polyurethane catalyst BL-17 is undoubtedly a brilliant pearl in the modern chemical industry. With its excellent performance and wide application range, it is ideal among many complex formulations. Just as a symphony requires a conductor to coordinate the sounds of various instruments, BL-17 is in this showA chemistry feast plays an indispensable role. Hopefully this article helps you get a more comprehensive understanding of this magic catalyst and realize its great potential in practical applications.
