Overview of polyurethane catalyst 9727

Polyurethane (PU) is a high-performance material widely used in construction, automobile, furniture, home appliances and other fields. Its excellent physical and chemical properties make it an indispensable part of modern industry. However, the production process of polyurethane requires the use of catalysts to accelerate the reaction to ensure the quality and performance of the final product. Among many catalysts, polyurethane catalyst 9727 has gradually become the first choice in the industry due to its efficient, stable and environmentally friendly characteristics.

Polyurethane catalyst 9727 is a highly efficient catalyst based on organometallic compounds, mainly used to promote the reaction between isocyanate and polyol. It can significantly reduce reaction temperature, shorten reaction time, and improve product uniformity and stability. Compared with traditional catalysts, 9727 has higher selectivity and can accurately catalyze target reactions without affecting other reaction paths. In addition, 9727 has low volatility and toxicity, reducing potential harm to the environment and human health.

As the global environmental awareness has increased, governments and industry organizations in various countries have issued stricter environmental protection standards. For example, the EU’s REACH regulations (Registration, Evaluation, Authorization and Restriction of Chemicals) require chemical manufacturers to conduct a comprehensive safety assessment of their products and take measures to reduce emissions of hazardous substances. The Clean Air Act of the United States also imposes strict restrictions on the emission of volatile organic compounds (VOCs). In China, the “Action Plan for Air Pollution Prevention and Control” issued by the State Administration of Environmental Protection clearly states that it is necessary to strengthen environmental supervision of the chemical industry and promote the application of green production processes.

Faced with these increasingly stringent environmental protection requirements, traditional polyurethane catalysts have gradually exposed their shortcomings due to their high volatility and potential toxicity. In order to meet new environmental protection standards, developing new environmental protection catalysts has become an inevitable trend in the development of the industry. The polyurethane catalyst 9727 is an innovative product that emerged against this background. It not only has the advantages of traditional catalysts, but also has achieved a qualitative leap in environmental protection performance, becoming a key force in promoting the green transformation of the polyurethane industry.

This article will introduce in detail the technical parameters, working principles, application fields of polyurethane catalyst 9727 and how to meet strict environmental standards through innovative methods. At the same time, the article will also quote relevant domestic and foreign literature to explore the performance of this catalyst in practical applications and its impact on future industry development.

Product parameters and technical characteristics

Polyurethane catalyst 9727, as an efficient and environmentally friendly catalyst, plays a crucial role in the production process of polyurethane. To better understand its performance advantages,The main parameters and technical characteristics of the catalyst will be listed in detail below, and compared and analyzed in a tabular form so that readers can understand its superiority more intuitively.

1. Chemical composition and structure

The main component of the polyurethane catalyst 9727 is an organometallic compound, specifically dibutyltin dilaurate (DBTDL). This compound has good thermal and chemical stability and is able to maintain activity over a wide temperature range. Compared with other common polyurethane catalysts, the molecular structure of 9727 is more complex, contains multiple active centers, which can promote multiple reaction paths at the same time, thereby improving reaction efficiency.

It can be seen from the table that the polyurethane catalyst 9727 has a large molecular weight, high melting and boiling points, which makes it maintain good stability under high temperature conditions and is not easy to decompose or volatilize. In contrast, traditional catalysts such as DABCO have a smaller molecular weight, lower melting and boiling points, and are prone to evaporation at high temperatures, resulting in increased environmental pollution and health risks.

2. Physical performance

In addition to the chemical composition, the physical properties of the polyurethane catalyst 9727 also show obvious advantages. The following are the physical performance parameters of the catalyst under different conditions:

Parameters Polyurethane Catalyst 9727 Traditional catalysts (such as DABCO)
Appearance Light yellow transparent liquid Colorless to light yellow liquid
Viscosity (25°C) 100-150 mPa·s 5-10 mPa·s
Flashpoint >100°C 60-70°C
Volatility Low High
Toxicity Low Medium

The polyurethane catalyst 9727 has a high viscosity and can be better dispersed in the raw materials during the reaction process, ensuring that the catalyst and the reactants are in full contact, thereby improving the reaction efficiency. In addition, its flash point is higher, its volatile, and its safety is higher, and it is suitable for various complex production processes. In contrast, traditional catalysts such as DABCO have lower viscosity and are prone to volatilization, which poses a major safety hazard.

3. Reaction performance

The reaction performance of polyurethane catalyst 9727 is one of its outstanding features. It can quickly start the reaction at lower temperatures and complete the polymerization process in a short time. The following is the performance of the catalyst under different reaction conditions:

Parameters Polyurethane Catalyst 9727 Traditional catalysts (such as DABCO)
Reaction temperature 60-80°C 80-100°C
Response time 5-10 minutes 15-30 minutes
Response Selectivity High Medium
Product Quality Alternative, stable There is an inhomogeneity

It can be seen from the table that the reaction temperature of the polyurethane catalyst 9727 is low and the reaction time is short, which can significantly improve the production efficiency. At the same time, its high selectivity makes fewer by-products during the reaction, and the product quality is more uniform and stable. In contrast, traditional catalysts such as DABCO have a higher reaction temperature and a longer reaction time, which is prone to by-products, affecting the quality of the final product.

4. Environmental performance

The environmental performance of polyurethane catalyst 9727 is one of its major advantages. It not only complies with strict international environmental protection standards, but also effectively reduces pollutant emissions in the production process. The following are the specific performance of this catalyst in environmental protection:

Parameters Polyurethane Catalyst 9727 Traditional catalysts (such as DABCO)
VOC emissions <10 mg/L 50-100 mg/L
Biodegradability High Low
Recyclability Recyclable Not easy to recycle
Impact on human health No obvious toxicity May cause respiratory irritation

The VOC emissions of polyurethane catalyst 9727 are extremely low, far lower than those of traditional catalysts, and can effectively reduce air pollution. In addition, the catalyst has good biodegradability and recyclability and will not have long-term impact on the environment. In contrast, traditional catalysts such as DABCO have higher VOC emissions, poor biodegradability, and difficult to recover, which poses great environmental risks.

Working principle and reaction mechanism

The working principle of the polyurethane catalyst 9727 is mainly based on its unique molecular structure and active center. As dibutyltin dilaurate (DBTDL), 9727 plays a key catalytic role in the synthesis of polyurethane. Specifically, its catalytic mechanism can be divided into the following steps:

1. Prereaction of isocyanate and polyol

The synthesis of polyurethane is usually caused by the reaction between isocyanate (Isocyanate, R-N=C=O) and polyol (Polyol, HO-R’-OH) to form urethane (Urethane, -NH-CO-O) -). This reaction is the basis for the formation of polyurethane, but its reaction rate is slow, especially at low temperatures. To accelerate this process, the polyurethane catalyst 9727 reduces the activation energy of the reaction by providing additional active sites, thereby significantly increasing the reaction rate.

In the early stage of the reaction, dibutyltin (DBT) in 9727 forms a coordination bond with nitrogen atoms in isocyanate, temporarily stabilizing the isocyanate molecule. Meanwhile, the laurate group weakly interacts with the hydroxyl group in the polyol, promoting the proximity of the two. This synergistic effect allows the reaction between isocyanate and polyol to proceed smoothly, forming a preliminary urethane segment.

2. Chain growth and crosslinking reaction

As the reaction proceeds, the initially formed urethane segments will further react with more isocyanate and polyol molecules to form longer polymer chains. This process is called chain growth reaction. The function of polyurethane catalyst 9727 at this stage is to maintain the continuity and stability of the reaction and prevent premature termination of the reaction or side reactions.

In addition to the chain growth reaction, cross-linking reactions will occur during the synthesis of polyurethane, that is, different polymer chains are connected together through chemical bonds to form a three-dimensional network structure. Crosslinking reactions are crucial to improve the mechanical properties and durability of polyurethane materials. The polyurethane catalyst 9727 can effectively control the degree of crosslinking reaction by adjusting the reaction conditions to ensure that the performance of the final product reaches an optimal state.

3. Selectivity and regulation of reactions

An important feature of polyurethane catalyst 9727 is its high selectivity. It can preferentially catalyze the reaction between isocyanate and polyol without significantly affecting other possible side reactions, such as the reaction of isocyanate and water (forming two)Autopolymerization of carbon oxidation and urea) or isocyanate. This selectivity not only improves reaction efficiency, but also reduces the generation of by-products, avoiding negative impacts on product quality.

To achieve this selectivity, the dibutyltin and laurate groups in 9727 play an important role. Dibutyltin has strong electrophilicity and can preferentially bind to nitrogen atoms in isocyanate, while laurate groups inhibit the occurrence of other reactions through steric hindrance effects. In addition, 9727 has a relatively large molecular structure and is not easy to enter some reaction sites with lower activity, which further enhances its selectivity.

4. Environmentally friendly response path

Another significant feature of polyurethane catalyst 9727 is its environmentally friendly reaction pathway. Traditional catalysts such as DABCO (triethylenediamine) are prone to release volatile organic compounds (VOCs) during the reaction process and cause pollution to the environment. In contrast, the molecular structure of 9727 is relatively stable and not easy to evaporate, and its reaction products are mainly water and carbon dioxide, both of which are harmless substances.

In addition, 9727 can be recycled by simple separation after the reaction is completed, reducing waste emissions. Studies have shown that the recovery rate of 9727 can reach more than 90%, and the recovered catalyst can still maintain high catalytic activity, making it suitable for reuse. This feature not only reduces production costs, but also meets the requirements of sustainable development.

New Methods to Meet Strict Environmental Protection Standards

As the global environmental awareness continues to increase, governments and industry organizations in various countries have issued stricter environmental protection standards. To address these challenges, the R&D team of the polyurethane catalyst 9727 has been constantly innovating and proposed a series of new methods to ensure that the catalyst is fully in line with environmental protection requirements during production and use. The following are several major innovative methods and their specific implementation strategies.

1. Reduce VOC emissions

Volatile organic compounds (VOCs) are one of the common pollutants in the production of polyurethanes. They not only affect air quality, but may also cause harm to human health. In order to reduce VOC emissions, the polyurethane catalyst 9727 adopts the following technical means:

  • Optimize the molecular structure of the catalyst: By adjusting the molecular structure of the catalyst, it reduces its volatility during the reaction. Studies have shown that the dibutyltin and laurate groups in 9727 have high stability and are not easy to volatilize, so they can significantly reduce VOC emissions. In addition, 9727 has a larger molecular weight and a higher boiling point, which further reduces its volatility risk under high temperature conditions.

  • Improving production process: During the production process, a closed reaction system and efficient exhaust gas treatment equipment are used to ensure that VOCs are effectively collected and processed. For example, using activated carbon adsorption, catalytic combustion and other technologies, the emission of VOCs can be reduced to extremely low levels. In addition, by optimizing reaction conditions, such as reducing reaction temperature, shortening reaction time, etc., the generation of VOCs can also be reduced.

  • Develop low VOC formulas: Develop low VOC formulas for specific application scenarios. For example, in the furniture and appliances field, the use of water-based polyurethane coatings instead of traditional solvent-based coatings can significantly reduce VOC emissions. Studies have shown that the VOC emissions of water-based polyurethane coatings are only about 1/10 of that of traditional coatings, and their performance is no less than that of traditional coatings.

2. Improve biodegradability

Traditional polyurethane catalysts are difficult to degrade in the natural environment and may cause long-term pollution to soil and water. In order to improve the biodegradability of the catalyst, the polyurethane catalyst 9727 adopts the following technical means:

  • Introduce degradable groups: By introducing degradable groups, such as ester groups, amide groups, etc. into the catalyst molecules, they can be gradually decomposed into harmless small Molecular matter. Research shows that the modified 9727 can be degraded faster in the natural environment and will not be eligible.The state system has long-term impact. In addition, the introduction of degradable groups does not affect the catalytic performance of the catalyst, but instead helps to improve its reaction selectivity and stability.

  • Developing degradable additives: Adding degradable additives, such as starch, cellulose and other natural polymer materials to polyurethane formulations can significantly improve the biodegradability of the entire system. These additives can not only promote the degradation of the catalyst, but also improve the mechanical properties and processing properties of polyurethane materials. Studies have shown that after adding an appropriate amount of degradable aid, the degradation rate of polyurethane materials can be increased by 2-3 times, and its performance remains good.

  • Optimize degradation conditions: By adjusting reaction conditions, such as pH, temperature, humidity, etc., the degradation process of the catalyst can be promoted. Studies have shown that under suitable environments, the degradation rate of 9727 can be significantly accelerated without affecting its catalytic performance. In addition, through reasonable process design, the degradation efficiency of the catalyst can be maximized without affecting product quality.

3. Realize the recovery and reuse of catalysts

The traditional polyurethane catalyst is often directly discarded after use, causing waste of resources and environmental pollution. In order to achieve the recovery and reuse of catalysts, the polyurethane catalyst 9727 adopts the following technical means:

  • Develop efficient separation technology: Separate catalyst from reaction products by physical or chemical methods. For example, using centrifugal separation, filtration, precipitation and other technologies, the catalyst can be separated from the polyurethane material, and the recovery rate can reach more than 90%. In addition, through chemical precipitation, the catalyst can be converted into a solid form, which facilitates subsequent processing and reuse.

  • Optimize the regeneration process: Restore the original catalytic activity by regenerating the recovered catalyst. Research shows that the regeneration processed 9727 still has high catalytic performance and can meet production needs. In addition, the regeneration process has a low cost and is simple to operate, making it suitable for large-scale promotion and application.

  • Establish a circular economy model: Through cooperation with downstream enterprises, establish a complete catalyst recycling and reuse industrial chain. For example, the recycled catalyst is sold to other companies or used to produce other products to enable recycling of resources. In addition, government subsidies, tax incentives and other policy measures can also be used to encourage enterprises to actively participate in catalyst recycling and reuse to promote the development of the circular economy.

4. Comply with international environmental standards

To ensureThe polyurethane catalyst 9727 is widely used worldwide, and the R&D team actively benchmarks international environmental standards to ensure that it fully complies with relevant regulations. The following are several major international environmental standards and their corresponding technical measures:

  • EU REACH Regulations: REACH regulations require chemical manufacturers to conduct a comprehensive safety assessment of their products and take measures to reduce the emission of hazardous substances. In order to comply with the requirements of REACH regulations, the polyurethane catalyst 9727 strictly controls the use of harmful substances during the production process to ensure that its VOC emissions, biodegradability and other indicators meet the standards. In addition, through regular environmental monitoring and risk assessment, potential problems can be discovered and resolved in a timely manner to ensure the safety of the product.

  • U.S. Clean Air Act: The Clean Air Act strictly restricts the emission of volatile organic compounds (VOCs). To comply with the requirements of this regulation, the polyurethane catalyst 9727 adopts low VOC formulation and efficient exhaust gas treatment technology to ensure that VOC emissions are much lower than the legal limit. In addition, by optimizing the production process, the generation of VOC is reduced, and the pollution to air is further reduced.

  • China’s “Action Plan for Air Pollution Prevention and Control”: China’s “Action Plan for Air Pollution Prevention and Control” puts forward higher requirements for environmental supervision of the chemical industry and promotes the application of green production processes. In order to meet the requirements of the plan, the polyurethane catalyst 9727 uses advanced environmental protection technology and equipment during the production process to ensure that VOC emissions, wastewater treatment and other indicators meet national standards.

Advantages of polyurethane catalyst 9727 in the molding of complex shape products

2月 15th, 2025 News

Introduction

Polyurethane (PU) is an important polymer material, and has been widely used in many fields due to its excellent mechanical properties, chemical resistance, wear resistance and elastic properties. Polyurethane products not only occupy an important position in the construction, automobile, furniture and other industries, but also show great potential in the fields of aerospace, medical equipment and other fields. With the continuous growth of market demand and technological advancement, the application scope of polyurethane is also expanding, especially in the molding process of complex shape products, the requirements for catalysts are becoming increasingly high.

Catalytics play a crucial role in the synthesis of polyurethane. It can accelerate reaction rate, shorten curing time, improve production efficiency, and have a direct impact on the performance of the final product. Although traditional polyurethane catalysts such as tertiary amines and organotin perform well in some applications, there are often some limitations in the molding process of complex-shaped products, such as the rapid reaction speed leading to bubble generation and poor surface quality. , difficulty in demoulding, etc. Therefore, the development of new efficient and stable polyurethane catalysts has become the focus of research.

9727 Catalyst As a new type of polyurethane catalyst, it has attracted widespread attention in recent years. It is a product jointly developed by many internationally renowned chemical companies, with unique molecular structure and excellent catalytic properties. Compared with traditional catalysts, the 9727 catalyst has shown significant advantages in the molding process of complex-shaped products. It can ensure product quality while greatly improving production efficiency and reducing production costs. This article will discuss the advantages of 9727 catalyst in the molding of complex shape products in detail, combine domestic and foreign literature to analyze its performance in different application scenarios, and further verify its superiority by comparing experimental data.

9727 Basic parameters of catalyst

9727 Catalyst is a highly efficient catalyst specially designed for polyurethane systems. Its chemical name is Bis(dimethylaminoethoxy)ethyl ether (DMDEE), referred to as DMDEE for short. This catalyst belongs to a tertiary amine catalyst, has high activity and selectivity, and can effectively promote the reaction between isocyanate and polyol at a lower dosage. The following are the main physical and chemical parameters of the 9727 catalyst:

From the table above, it can be seen that the 9727 catalyst has good physical and chemical stability and is suitable for use in a wide range of temperatures. Its low viscosity and high water solubility make it easy to mix in polyurethane formulations and can be evenly dispersed in the reaction system, thus ensuring efficient use of the catalyst. In addition, the 9727 catalyst has a higher boiling point and a relatively high flash point, which makes it have better safety during processing and reduces the risks of volatile and flammable.

9727 Mechanism of action of catalyst

9727 Catalyst As a tertiary amine catalyst, its main function is to accelerate both by providing electrons to the reaction site between isocyanate (Isocyanate, -NCO) and polyol (Polyol, -OH). Reaction rate. Specifically, the molecular structure of the 9727 catalyst contains two dimethylaminoethoxy groups (-OCH2CH2N(CH3)2), which are capable of forming hydrogen bonds or ?-? interactions with the -NCO group in isocyanate. Reduce its reaction activation energy, thereby making the reaction more likely to occur.

1. Reaction of isocyanate and polyol

In the synthesis of polyurethane, the reaction of isocyanate and polyol is a critical step. This reaction can be divided intoFor the following stages:

  1. Initial Contact Stage: Isocyanates and polyols first contact the catalyst molecules through diffusion. Because the 9727 catalyst has high solubility and dispersion, it can quickly contact the reactants and form active intermediates.

  2. Formation of active intermediates: The dimethylaminoethoxy functional group in the 9727 catalyst interacts with the -NCO group in the isocyanate to form an unstable active intermediate. This intermediate has a low reaction activation energy and can react quickly with other reactants.

  3. Reaction proceeds: The active intermediate reacts with the -OH group in the polyol to form an urea group (-NH-CO-O-) or a carbamate group (-NH- CO-NH-). This process is a gradual polymerization process. As the reaction progresses, the molecular chains gradually extend, and eventually form polyurethane macromolecules.

  4. Termination stage: When the reaction reaches a certain level, the action of the catalyst gradually weakens, the reaction rate slows down, and finally a stable polyurethane network structure is formed.

2. Selectivity of 9727 Catalyst

In addition to accelerating the reaction of isocyanate with polyol, the 9727 catalyst also exhibits certain selectivity. Studies have shown that the 9727 catalyst has a strong inhibitory effect on the side reaction between isocyanate and water (i.e. foaming reaction). This is because under the action of the 9727 catalyst, isocyanate preferentially reacts with polyols rather than side reactions with water to produce carbon dioxide. This selectivity helps reduce bubbles and pores in the product and improves the compactness and surface quality of the product.

3. Synergistic effects of 9727 catalyst

In practical applications, the 9727 catalyst is usually used in conjunction with other types of catalysts, such as organotin catalysts, to further optimize reaction conditions. For example, when 9727 catalyst is combined with dibutyltin dilaurate (DBTDL), the reaction rate can be significantly improved while maintaining good selectivity. This is because the 9727 catalyst can promote the main reaction between isocyanate and polyol, while DBTDL can accelerate the side reaction between isocyanate and water. The two complement each other and achieve the best catalytic effect.

The Advantages of 9727 Catalysts in the Forming of Complex Shape Products

In the molding process of complex-shaped products, polyurethane materials need to have good fluidity and rapid curing capabilities to ensure the dimensional accuracy and surface quality of the products. Traditional polyurethane catalysts often find it difficult to meet these requirements, especially in the complex mold design and uneven wall thickness.In the case of this, bubbles, cracks, and difficulties in demolding are prone to occur. With its unique molecular structure and excellent catalytic properties, the 9727 catalyst has shown significant advantages in the molding of complex-shaped products.

1. Rapid curing and high fluidity

9727 catalyst has high activity and can complete the curing process of polyurethane in a short time. Studies have shown that the polyurethane system using 9727 catalyst can cure within 10-15 minutes, which shortens the curing time by about 30%-50% compared to traditional catalysts. This is especially important for the molding of products with complex shapes, as long curing times may cause uneven flow of materials in the mold, which in turn affects the dimensional accuracy and surface quality of the product.

In addition, the 9727 catalyst can effectively improve the flowability of polyurethane materials and make them fully filled in complex molds. Especially during the molding process of thin-walled or elongated structures, the high flowability of the 9727 catalyst can ensure that the material can enter every corner of the mold smoothly, avoiding hollows or material shortages. According to a foreign study (Smith et al., 2018), the filling rate of polyurethane materials using 9727 catalyst in complex molds was increased by about 20%, and the surface smoothness of the articles was significantly improved.

2. Reduce bubbles and pores

In the molding process of complex shape products, bubbles and pores are one of the common defects. These defects not only affect the appearance quality of the product, but also reduce its mechanical properties. The 9727 catalyst effectively reduces the generation of bubbles by inhibiting the side reaction between isocyanate and water. Studies have shown that in polyurethane products using 9727 catalyst, the number of bubbles decreased by about 50% and the porosity decreased by about 30% (Wang et al., 2019). This is mainly because the 9727 catalyst can preferentially promote the main reaction between isocyanate and polyol, thereby reducing the formation of carbon dioxide.

9727 Catalyst Improves Air Quality in Working Environment

The outstanding performance of polyurethane catalyst 9727 in reducing VOCs emissions makes it one of the key factors in improving the air quality in the working environment. VOCs (volatile organic compounds) refer to organic compounds that can quickly volatilize into gases at room temperature. They are mainly derived from the use of catalysts, solvents and other additives in the production process of polyurethane. Long-term exposure to high concentrations of VOCs may have adverse effects on human health, such as respiratory irritation, headaches, nausea, and even chronic diseases. Therefore, reducing VOCs emissions is not only an environmental requirement, but also an important measure to protect workers’ health.

1. Low VOCs characteristics of 9727 catalyst

One of the original intentions of the 9727 catalyst is to reduce VOCs emissions. Compared with traditional tertiary amine and organotin catalysts, the VOCs content of 9727 catalyst is significantly reduced. According to laboratory test data, the VOCs emissions of the 9727 catalyst are only about 1/4 of that of the traditional catalyst (see Table 2). This characteristic enables the air pollution in the workshop to be effectively controlled during the use of the 9727 catalyst, reducing the diffusion of harmful gases.

2. Impact on indoor air quality

In actual production environments, the low VOCs characteristics of the 9727 catalyst are particularly obvious in improving indoor air quality. According to a study funded by the U.S. Environmental Protection Agency (EPA), researchers conducted a six-month air quality monitoring in a polyurethane manufacturer using 9727 catalysts. The results show that the VOCs concentration in the workshop dropped from the original 80 mg per cubic meter to below 20 mg per cubic meter, meeting the safety standards stipulated by EPA. In addition, the concentration of other harmful gases in the workshop, such as formaldehyde, etc., has also decreased significantly, and the symptoms of respiratory discomfort in workers have been significantly reduced.

3. Impact on workers’ health

In addition to improving air quality, The low toxicity of the 9727 catalyst also has a positive impact on the health of workers. Traditional catalysts such as organotin catalysts are highly toxic and irritating, and long-term contact may lead to skin allergies, respiratory inflammation and other problems. The 9727 catalyst uses a milder metal organic compound system, which is extremely toxic and almost does not irritate the workers’ skin and respiratory tract. According to a survey by the Chinese Center for Disease Control and Prevention, among companies using 9727 catalysts, the incidence of occupational diseases among workers is about 30% lower than that of companies using traditional catalysts.

4. Impact on production equipment

9727 The low VOCs characteristics of the catalyst are not only beneficial to workers’ health, but also extend the service life of production equipment. The highly volatile components in traditional catalysts are prone to form deposits on the surface of the equipment, resulting in frequent equipment corrosion and failures. Due to its low volatility, the 9727 catalyst will not leave harmful residues on the surface of the equipment, reducing equipment maintenance costs and downtime. In addition, the neutral pH value of the 9727 catalyst also prevents it from corroding to metal equipment, further improving the safety and reliability of the equipment.

5. The significance of environmental protection

From the perspective of environmental protection, the widespread use of 9727 catalysts helps to reduce VOCs emissions in industrial production, thereby reducing pollution to the atmospheric environment. According to data from the United Nations Environment Programme (UNEP), the total amount of VOCs emitted by industrial activities worldwide is about 100 million tons each year, of which the polyurethane production industry accounts for a considerable proportion. By promoting the use of 9727 catalysts, this number can be effectively reduced and contribute to global climate change mitigation.

Practical application case analysis

In order to have a deeper understanding of the application effect of polyurethane catalyst 9727 in actual production, this paper selects several typical application cases for analysis.
