Among them, tertiary amine catalysts occupy an important position in the polyurethane industry due to their efficient catalytic action and good selectivity.

In recent years, with the increasing global emphasis on environmental protection and sustainable development, the market demand for high-performance and low-emission polyurethane products is growing. Against this background, the research and development and application of a new generation of high-efficiency catalysts are particularly important. The tertiary amine polyurethane catalyst BL-17 came into being. With its unique chemical structure and excellent performance, it has become an ideal choice to meet the market demand of high-standard polyurethane in the future.

This article will conduct in-depth discussion on the technical characteristics, application advantages and their important role in promoting industry progress. Through detailed data analysis and rich case studies, we will fully analyze how this catalyst can help the polyurethane industry move towards a greener and more efficient future.

1. Overview of tertiary amine polyurethane catalyst

(I) What is a tertiary amine catalyst?

Term amine catalysts are an organic compound that contains nitrogen atoms and does not directly attach hydrogen atoms to the nitrogen atoms. This type of catalyst is usually highly alkaline and can effectively promote the reaction between isocyanate (NCO) and polyol (OH), thereby accelerating the formation process of polyurethane. Compared with traditional tin-based catalysts, tertiary amine catalysts not only have higher catalytic efficiency, but also show better environmental friendliness, so they are highly favored in modern polyurethane production.

(II) Basic characteristics of BL-17

Term amine polyurethane catalyst BL-17 is a highly efficient catalyst designed specifically for the production processes of hard and soft bubble polyurethane. Its molecular structure has been optimized to achieve significant catalytic effects at a lower dose, while avoiding the possible side reaction problems caused by traditional catalysts. The following are the main technical parameters of BL-17:

parameter name	Value Range or Description
Chemical Components	Composite tertiary amine
Appearance	Slight yellow to amber transparent liquid
Density (25℃)	0.98~1.02 g/cm³
Viscosity (25℃)	30~50 mPa·s
Water-soluble	Slightly soluble
Flashpoint	>60℃
pH value (1% aqueous solution)	8.5~9.5

It can be seen from the table that BL-17 has moderate density and viscosity, which is easy to store and use; at the same time, its weak water solubility and high flash point also make it safer and more reliable in actual operation.

2. The core advantages of BL-17

(I) High-efficiency catalytic performance

The major feature of BL-17 is its extremely high catalytic efficiency. In the production of rigid polyurethane foam, BL-17 can significantly shorten the foaming time and improve production efficiency. Specifically, it can work through the following mechanisms:

Promote NCO-OH reaction: BL-17 can effectively reduce the activation energy of the reaction between isocyanate and polyol, thereby accelerating the reaction rate.
Inhibition of side reactions: Unlike other catalysts, BL-17 has a good inhibitory effect on side reactions caused by moisture (such as carbon dioxide release), which helps to reduce the occurrence of problems such as foam collapse.

Experimental data show that under the same conditions, the rigid foam prepared with BL-17 has lower density, smaller thermal conductivity, and better overall performance than the products prepared by traditional catalysts.

(II) Excellent environmental compatibility

As the global environmental protection regulations become increasingly strict, enterprises’ attention to green chemical products has been increasing. As a new environmentally friendly catalyst, BL-17 is in line with this trend. Its main advantages include:

Low toxicity: The toxicity of BL-17 is much lower than that of traditional tin-based catalysts, and has a less impact on human health.
Degradability: This catalyst is easy to decompose in the natural environment and does not cause persistent pollution.
No heavy metal residue: Because it does not contain any heavy metal components, BL-17 will not bring potential environmental pollution risks to the final product.

These characteristics make BL-17 It is especially suitable for use in areas such as food packaging and medical devices that require high sanitary conditions.

(III) Wide scope of application

BL-17 is not only suitable for the production of rigid polyurethane foam, but can also be widely used in soft foam, coatings, adhesives and other fields. For example:

In soft foam, BL-17 can improve the feel and elasticity of the foam and improve the comfort of the product.
In the field of coatings, BL-17 helps to form a more uniform and denser coating, enhancing weather resistance and adhesion.
In the adhesive formula, BL-17 can significantly increase the curing speed and meet the needs of rapid construction.

This versatility provides users with greater flexibility and also reduces the procurement costs of enterprises.

III. Technical principles and mechanism of BL-17

To understand why BL-17 is so good, we need to have a deeper understanding of the chemistry behind it. The following is a detailed analysis of its core mechanism of action:

(I) Catalytic reaction path

BL-17 mainly participates in the synthesis process of polyurethane through the following two methods:

Promote the addition reaction between hydroxyl groups and isocyanate:
- Under the action of BL-17, the NCO groups in the isocyanate molecule are more likely to react with the OH groups in the polyol molecule to form a urethane structure.
- This process significantly improves the reaction rate while reducing the residual amount of unreacted raw materials.
Adjust the gas generation rate during foaming:
- When there is trace amount of water in the system, BL-17 will preferentially bind to water molecules to form a stable intermediate, thereby delaying the release rate of carbon dioxide.
- This “buffering effect” ensures that the foam structure is more uniform and stable, and avoids defects caused by the rapid release of gas.

(Bi) Advantages of molecular structure

The molecular structure of BL-17 has been carefully designed to make it both high activity and stability. Its key characteristics include:

Multi-site synergy: BL-17 molecules contain multiple tertiary amine groups, which can interact with multiple reactant molecules at the same time, thereby greatly improving catalytic efficiency.
Satellite Steady Resistance Effect: The special three-dimensional configuration allows it to be effectively avoided during the catalysis processThe necessary side reactions ensure the purity of the main reaction.

In addition, BL-17 also has a certain antioxidant ability and can maintain high activity after long-term storage.

IV. Analysis of application case of BL-17

In order to better illustrate the practical application value of BL-17, we selected several typical cases for in-depth analysis.

(I) Refrigerator insulation layer manufacturing

The performance of the refrigerator insulation layer directly affects the energy consumption level of the entire machine. After using BL-17 as a catalyst, a well-known home appliance manufacturer successfully achieved the following improvements:

Thermal conductivity coefficient (W/m·K)	0.022	0.020	↓9.1%
Foaming time (s)	120	90	↓25%

The data show that the use of BL-17 not only improves the thermal insulation performance of the foam, but also greatly shortens the production cycle, bringing significant economic benefits to the company.

(II) Car seat foam production

In the automotive industry, comfort and safety are the focus of consumers. An international automotive parts supplier has solved the problem of foam collapse caused by traditional catalysts by introducing BL-17 and achieved the following optimizations:

Indicators	Before improvement	After improvement	Elevation
