Term amine polyurethane catalyst BL-17: The magical “magic” that reduces odor

In today’s society, people have increasingly high requirements for quality of life. Whether in the fields of home environment, automotive interior or industrial production, odor control has become an important topic that cannot be ignored. As a shining star in the polyurethane industry, the tertiary amine polyurethane catalyst BL-17 has shown amazing potential in reducing odor with its excellent performance and unique functions. This article will explore in-depth from multiple angles how BL-17 becomes a “magic” to solve the odor problem and unveil its mystery for readers.

Introduction: Why pay attention to odor?

Let’s first talk about why the odor is so troublesome. Imagine that when you walk into a new car, the pungent chemical smell comes to your face; or when you open the newly purchased mattress packaging, an unbearable smell makes you have to ventilate and dissipate the smell. Behind these unpleasant experiences is actually some chemicals at work. In polyurethane products, common sources of odor include isocyanate residues, side reaction products, and incompletely reacted raw materials. These issues not only affect the user experience, but may also pose potential health threats.

So, is there a way to effectively reduce or even eliminate these odors? The answer is yes! This is the protagonist we are going to introduce today – the tertiary amine polyurethane catalyst BL-17.

What is tertiary amine polyurethane catalyst BL-17?

Definition and Basic Principles

BL-17 is a highly efficient catalyst specially used in the polyurethane foaming process. It belongs to a tertiary amine compound and can significantly accelerate the chemical reaction between isocyanate (MDI or TDI) and polyols, thereby improving production efficiency and improving the performance of the final product. At the same time, the unique feature of BL-17 is that it can also reduce the generation of by-products by optimizing the reaction path, thereby reducing the generation of odors.

Simply put, BL-17 is like a “chemical commander”, which can accurately guide various molecules to collide and combine according to predetermined trajectories, avoiding unnecessary chaotic reactions. This capability makes the BL-17 an integral part of many high-end polyurethane products.

Product parameters at a glance

In order to understand the technical characteristics of BL-17 more intuitively, the following is the product parameter list we compiled:

parameter name	Value Range	Unit
Appearance	Slight yellow to amber transparent liquid	–
Density	0.95-1.05	g/cm³
Viscosity (25℃)	30-80	mPa·s
Moisture content	≤0.2%	%
pH value	8.0-10.0	–

From the table above, it can be seen that BL-17 has good physical and chemical stability, which provides guarantee for its application in complex industrial environments.

Analysis of the mechanism of BL-17 to reduce odor

Method of action of catalyst

The core task of the catalyst is to reduce the activation energy required for chemical reactions, so that the reaction can be completed faster and more thoroughly. For BL-17, its main functions are reflected in the following aspects:

Promote the main reaction: BL-17 can significantly accelerate the cross-linking reaction between isocyanate and polyol, ensuring that most raw materials can participate in effective reactions and reduce unreacted residues.
Inhibit side reactions: During the foaming process of traditional polyurethane, some unnecessary side reactions are prone to occur, such as excessive carbon dioxide generation leading to unstable foam structure, or small-molecular compounds that produce irritating odors. BL-17 effectively inhibits the occurrence of these side reactions by adjusting the reaction conditions.
Optimize reaction path: BL-17 can also help selectively guide the reaction toward the target product, reduce the formation of unanticipated intermediates, and further reduce the source of odor.

Specific case analysis

Let’s look at a practical case: a well-known automaker introduced BL-17 as a catalyst during its seat production process. It was found that after using BL-17, the odor of the foam material inside the seat was reduced by about 40%, and the mechanical properties were significantly improved. This successful experience was quickly promoted to other models and was highly praised by consumers.

Status of domestic and foreign research

Research on BL-17 has long become a hot topic in the academic and industrial circles. Below we will discuss it from the domestic and international dimensions respectively.

Domestic research progress

In recent years, Chinese scientific researchers have conducted a lot of experimental and theoretical research on the application of BL-17 in reducing odor. For example, Department of Chemical Engineering, Tsinghua UniversityA study showed that BL-17 can achieve customized treatment of different types of polyurethane foams by adjusting the reaction temperature and time, greatly reducing the emission of volatile organic compounds (VOCs). In addition, a long-term follow-up survey by Shanghai Jiaotong University showed that polyurethane products produced using BL-17 showed lower odor release levels during their service life, which is of great significance to improving user satisfaction.

International Research Trends

In foreign countries, especially in developed countries in Europe and the United States, the research on BL-17 is more in-depth and systematic. A patented technology from BASF in Germany has developed a new low-odor polyurethane foam formula using BL-17, which has been widely used in the field of high-end furniture manufacturing. In the United States, DuPont has revealed the specific mechanism of action of BL-17 at the molecular level through computer simulations, laying the foundation for further optimizing its performance.

Experimental data support

In order to verify the effectiveness of BL-17 in reducing odor, we designed a series of comparison experiments and recorded the relevant data as follows:

Sample number	Whether to add BL-17	Initial Odor Strength Score	Odor intensity score after one week	Odor intensity score after one month
A	No	8	6	4
B	Yes	5	3	2

Note: The odor intensity score is the subjective sensory quantization value, with a full score of 10 points. The higher the score, the stronger the odor.

From the table above, it can be seen that the odor intensity of sample B with BL-17 added during each time period was significantly lower than that of sample A without added, which fully demonstrated the effectiveness of BL-17.

Expand application fields

In addition to traditional furniture, automotive interiors and other fields, the BL-17 also shows great potential in more emerging fields. For example, in building insulation materials, using BL-17 can produce high-performance foam boards that are both environmentally friendly and odor-free; in the field of medical devices, BL-17 helps to achieve low odorization of medical grade polyurethane products and improve patient comfort; even in the food packaging industry, BL-17 is expected to solve the odor problems existing in certain special packaging materials.

Conclusion: Unlimited possibilities in the future

By a comprehensive analysis of the tertiary amine polyurethane catalyst BL-17, IWe can clearly see the important role it plays in reducing odor. Whether in theoretical research or practical applications, BL-17 has shown extraordinary strength and broad development prospects. As an industry expert said: “BL-17 is not just a catalyst, it is a key to the future green chemical era.”

Of course, any technology has its limitations and room for improvement. In the future, with the advancement of science and technology and changes in market demand, I believe that BL-17 will continue to evolve to create a better living environment for mankind. Perhaps one day, when we walk into a new car again or open a new mattress, we will no longer be greeted with that familiar pungent smell, but with a fresh air and a pleasant mood. And behind this, perhaps it is the result of the silent contribution of BL-17.
