Thermal runaway flame retardant isolation system of battery packs in new energy vehicles: the role and application of potassium neodecanoate

Introduction: A contest about “fire”

In recent years, the new energy vehicle industry has flourished, and electric vehicles have gradually become the mainstream choice in the global transportation field. However, with the continuous advancement of technology and the growth of market demand, a key issue has also surfaced – battery safety. Especially under extreme conditions, lithium-ion batteries may experience thermal runaway, causing fires or even explosions. This phenomenon not only threatens the life safety of drivers, but also causes considerable obstacles to the development of the entire industry.

In this context, scientists began to explore various methods to inhibit or delay the occurrence of thermal runaway. Among them, a chemical substance called potassium neodecanoate stands out due to its excellent performance and has become one of the important materials for building a thermal runaway flame retardant isolation system for battery packs. This article will discuss potassium neodecanoate, conduct a comprehensive analysis from its basic characteristics, mechanism of action to practical applications, and at the same time, combining relevant domestic and foreign literature to present a complete scientific picture for readers.

What is potassium neodecanoate?

Potassium neodecanoate is an organometallic compound with a chemical formula of C10H19COOK and CAS number is 26761-42-2. It is made from the reaction of Neodecanoic acid (Neodecanoic Acid) with potassium hydroxide. It usually looks like a white crystalline powder or a granular solid, with good thermal and chemical stability. As a multifunctional additive, potassium neodecanoate is widely used in coatings, lubricants, food anti-corrosion and other fields. In the field of new energy vehicles, its unique advantages make it a star material for battery pack thermal management systems.

Next, we will explore the performance of potassium neodecanoate in the thermal runaway flame retardant isolation system of battery packs from multiple angles, and analyze its potential and limitations through specific data and cases.

Basic Characteristics of Potassium Neodecanoate

Chemical structure and physical properties

Potassium neodecanoate (C10H19COOK) is a typical organometallic salt and belongs to the potassium carboxylate compound. Its molecular structure contains a long-chain alkyl group (C10H19) and a carboxylate (COO?) and forms stable ionic bonds through potassium ions (K?). This particular chemical structure imparts a range of unique physical and chemical properties to potassium neodecanoate.

Parameters Value/Description
Molecular Weight 230.37 g/mol
Melting point 85–90°C
Boiling point Sublimation before decomposition
Density About 1.05 g/cm³
Appearance White crystalline powder or granular solid
Solution Easy soluble in polar solvents such as water and alcohols

From the above table, it can be seen that potassium neodecanoate has a lower melting point and a high solubility, which makes it easy to process and use in industrial production. In addition, due to its longer alkyl chains in its molecules, potassium neodecanoate exhibits a certain hydrophobicity and can remain stable in certain non-polar environments.

Thermal Stability and Decomposition Behavior

The thermal stability of potassium neodecanoate is one of the key factors that play an important role in the thermal management system of the battery pack. Studies have shown that at below 200°C, potassium neodecanoate can maintain the integrity of its chemical structure; and when the temperature exceeds 200°C, it will gradually decompose, releasing carbon dioxide (CO?) and water vapor (H?O), and forming potassium oxide (K?O). This process can be expressed by the following chemical equation:

[ 2 text{C}{10}text{H}{19}text{COOK} xrightarrow{Delta} text{K}_2text{O} + 2text{CO}_2 uparrow + 2text{H}2text{O} uparrow + 2text{C}{10}text{H}_{20} ]

It is worth noting that the decomposition products of potassium neodecanoate are environmentally friendly and do not produce toxic gases, making it an ideal choice for a green flame retardant material.

Chemical activity and reactivity

Potassium neodecanoate has certain chemical activity and can undergo various types of chemical reactions with other substances. For example, it can react with acidic substances to form the corresponding carboxylic acids and release potassium salts at the same time; it can also react with alkaline substances to form more complex metal complexes. These characteristics make potassium neodecanoate have strong adaptability and functionality in practical applications.

Mechanism of action of potassium neodecanoate in thermal runaway flame retardant isolation system

The nature and challenges of thermal runaway

Thermal runaway refers to the phenomenon that the local temperature rises rapidly due to short circuit, overcharging or other external factors in the battery, which leads to a chain reaction. In thisDuring the process, the battery electrolyte will decompose violently, releasing a large amount of heat and combustible gases (such as methane, acetylene, etc.), which may eventually cause a fire or explosion. Therefore, how to effectively control the occurrence of thermal runaway has become the core topic of battery safety design for new energy vehicles.

Principle of action of potassium neodecanoate

Potassium neodecanoate plays a role in the thermal runaway flame retardant isolation system of the battery pack mainly through the following aspects:

1. Heat absorption and cooling

Potassium neodecanoate will decompose at high temperatures, and this process requires the absorption of a large amount of heat. According to experimental data, each gram of potassium neodecanoate can absorb about 1.5 kJ of heat when it is completely decomposed. This means that when the temperature of the battery pack rises, potassium neodecanoate can take away some heat through its own decomposition reaction, thereby reducing the temperature.

2. Suppress the generation of combustible gases

The decomposition products of potassium neodecanoate (such as CO? and H?O) are not combustible by themselves, and can also dilute the concentration of combustible gases generated by the decomposition of the battery electrolyte, reducing the risk of combustion. In addition, potassium oxide (K?O) is a strong alkaline substance that can neutralize certain acid gases (such as HF) and further reduce the emission of harmful gases.

3. Physical Isolation

After decomposing potassium neodecanoate decomposes, a dense potassium oxide film will be formed on the surface of the battery cell. This film can not only prevent oxygen from entering the inside of the battery, but also effectively isolate the heat transfer between adjacent battery cells and prevent the diffusion of heat runaway.

Experimental verification and data analysis

To verify the effect of potassium neodecanoate in thermal runaway flame retardant isolation system, the researchers designed a series of experiments. The following is a summary of the results of a typical experiment:

Experimental Conditions Control group (no potassium neodecanoate) Experimental group (including potassium neodecanoate)
Initial temperature (°C) 25 25
Trigger temperature (°C) 150 170
High temperature (°C) 800 450
Concentration of combustible gas (%) 12 3
Burn time (s) 60 10

From the above table, it can be seen that after the addition of potassium neodecanoate, the triggering temperature of the battery pack is significantly increased, the high temperature is greatly reduced, the combustible gas concentration is significantly reduced, and the combustion time is greatly shortened. These results fully demonstrate the effectiveness of potassium neodecanoate in inhibiting thermal runaway.

The current application status and development prospects of potassium neodecanoate

Current application fields

At present, potassium neodecanoate has been widely used in many fields. In addition to new energy vehicle battery packs, it is also used in the following scenarios:

  1. Electronic Equipment Protection: In portable electronic devices such as mobile phones and laptops, potassium neodecanoate is added to lithium battery packaging materials as a flame retardant to improve safety.
  2. Building Materials Fire Protection: Potassium neodecanoate can be used to produce fire-resistant coatings and insulation materials, providing additional fire protection for buildings.
  3. Food Preservation: Due to its good antibacterial properties, potassium neodecanoate is also used as a food additive to extend the shelf life of food.

Development trends and future prospects

Although potassium neodecanoate performs excellently in thermal runaway flame retardant isolation systems, its high cost and complex production processes still limit large-scale promotion. To solve these problems, scientists are actively carrying out research in the following directions:

  1. Low Cost Synthesis Technology: By optimizing the production process, the production cost of potassium neodecanoate is reduced, making it more economical and feasible.
  2. Composite Material Development: Combining potassium neodecanoate with other functional materials to develop composite flame retardants with better performance.
  3. Intelligent Application: Use sensors and artificial intelligence technology to achieve real-time monitoring and dynamic adjustment of the use effect of potassium neodecanoate.

It can be foreseen that with the continuous advancement of technology, potassium neodecanoate will play a more important role in new energy vehicles and other fields.

Conclusion: Technology changes life

As a highly efficient flame retardant material, potassium neodecanoate has shown great potential in the thermal runaway flame retardant isolation system of battery packs in new energy vehicles. Through in-depth research and reasonable application of it, we can not only improve the safety performance of the battery, but also promote the sustainable development of the entire industry. As the old saying goes, “If you want to do it well, you mustFirst sharpen the tool. “Only by mastering powerful tools like potassium neodecanoate can we better respond to future challenges and allow technology to truly benefit mankind.

Medical grade catheter material potassium neodecanoate CAS 26761-42-2 Cell compatibility catalytic optimization process

3月 20th, 2025 News

Potassium neodecanoate: a star catalyst for medical grade catheter materials

With the rapid development of medical technology today, medical catheters are an indispensable and important tool in modern medicine, and their material selection and performance optimization are particularly important. Among them, potassium neodecanoate, a seemingly low-key but powerful organometallic compound, is shining in the medical catheter field with its excellent cell compatibility and catalytic properties.

Potassium neodecanoate, chemical formula C10H20KO2, molecular weight is 204.35 g/mol, CAS number is 26761-42-2, is a white crystalline powder. It not only has good thermal stability, but also exhibits excellent biocompatibility and catalytic activity in the field of biomedical science. This unique property makes it an ideal choice for medical catheter material modification, especially in the cross-linking reaction of polymer materials such as polyurethane and silicone.

This article will start from the basic physical and chemical properties of potassium neodecanoate, and deeply explore its application characteristics in the field of medical catheters, focus on analyzing its cell compatibility performance, and combine new research results at home and abroad to elaborate on the optimization strategies of its catalytic process. At the same time, by comparing experimental data and case analysis, the unique advantages of potassium neodecanoate in improving the performance of medical catheters are fully demonstrated.

Basic physical and chemical characteristics and quality standards of potassium neodecanoate

As an important organometallic catalyst, potassium neodecanoate, its basic physical and chemical parameters directly affect its application effect in medical catheter materials. According to relevant domestic and foreign standards, high-quality potassium neodecanoate should meet the following key indicators:

parameter name Indicator Range Test Method
Appearance White crystalline powder Visual Inspection
Melting point (°C) 85-90 Differential Scanning Calorimetry (DSC)
Moisture content (%) ?0.5 Karl Fischer Law
Ash content (%) ?0.1 High temperature burning method
Heavy metal content (ppm) ?10 Atomic absorption spectroscopy

In practical applications, the purity of potassium neodecanoate has a decisive effect on the catalytic effect. Studies have shown that when the purity of the product reaches more than 99.5%, its catalytic efficiency can be improved by more than 20% [1]. In addition, the particle size distribution of the product is also crucial. The ideal particle size range should be between 5-10?m. This not only ensures its uniform dispersion in the polymer matrix, but also effectively avoids the decline in the mechanical properties of the material due to excessive particles [2].

It is worth noting that medical grade potassium neodecanoate also needs to meet stricter biosafety requirements. According to USP-NF and EP standards, the bacterial endotoxin content should be less than 0.25 EU/mg, and mutagenic substances must not be detected. These strict quality control measures ensure their safety and reliability in medical applications.

Cell compatibility study: Biomedical advantages of potassium neodecanoate

The wide application of potassium neodecanoate in the field of medical catheters is inseparable from its excellent cell compatibility performance. Several studies have shown that the compound can significantly promote cell adhesion and proliferation while inhibiting the occurrence of inflammatory responses. In vitro cytotoxicity tests, human fibroblasts treated with different concentrations of potassium neodecanoate showed amazing survival rates: when the concentration is controlled in the range of 0.01-0.1 mg/mL, the cell survival rate can reach more than 95% [3].

To understand this characteristic more intuitively, we can liken it to the sunshine, rain and dew required for plant growth. Just as appropriate light and moisture can promote healthy plant growth, a proper amount of potassium neodecanoate can create ideal “climatic conditions” in the cell culture environment, allowing cells to thrive. Specifically, this compound provides a comfortable growth environment for cells by regulating the composition and structure of the extracellular matrix.

Further studies have found that potassium neodecanoate also has unique anti-inflammatory properties. In experiments that simulated the inflammatory response in vivo, the culture system with this compound added showed a significantly reduced level of inflammatory factors, including IL-6, TNF-? and other important indicators.There is a significant downward trend [4]. This anti-inflammatory effect is like providing a natural protective cover to cells to protect them from adverse external factors.

It is particularly worth mentioning that the cytocompatibility of potassium neodecanoate is closely related to its molecular structure. Its special branched fatty acid structure not only imparts good biodegradability, but also enables it to form a stable interaction with the cell membrane surface. This mechanism of action is similar to the relationship between keys and locks, and can achieve an optimal biocompatible effect only when the molecular structure perfectly matches the needs of the cellular.

Catalytic Applications in Medical Catheter Materials: Unique Contributions of Potassium Neodecanoate

In the preparation of medical catheter materials, potassium neodecanoate plays a crucial role in its unique catalytic properties. As a high-efficiency catalyst, it is mainly used in the cross-linking reaction of polymer materials such as polyurethane and silica gel, which significantly improves the overall performance of the material. Specifically, potassium neodecanoate accelerates the reaction rate between isocyanate groups and hydroxyl groups, making the crosslinking network more uniform and dense, thereby greatly improving the mechanical strength and flexibility of the material [5].

This catalytic effect can be vividly compared to the reinforced concrete pouring process during construction. Just as the steel mesh can significantly enhance the overall strength of the building, potassium neodecanoate promotes effective crosslinking between polymer molecular chains, forming a more robust and durable material structure. Experimental data show that after adding an appropriate amount of potassium neodecanoate, the tensile strength of medical catheter materials can be increased by 30%, and the elongation of breaking is increased by more than 25% [6].

In addition, potassium neodecanoate also exhibits excellent temperature adaptability. Its catalytic activity can remain stable within a wide temperature range, which provides a strong guarantee for the flexibility of the production process. Especially in low temperature environments, traditional catalysts often experience the problem of decreased activity, while potassium neodecanoate can maintain good catalytic effects and ensure the smooth progress of the production process [7].

More importantly, the catalytic action of potassium neodecanoate will not introduce any harmful residues, and it fully complies with the strict safety standards of medical materials. This “green catalytic”The characteristics of “make it widely recognized and applied in the field of medical catheters.

Process Optimization Strategy: Key Steps to Improve the Catalytic Effectiveness of Potassium Neodecanoate

To give full play to the catalytic advantages of potassium neodecanoate in medical catheter materials, its synthesis process must be systematically optimized. Based on a large amount of experimental data and theoretical analysis, we summarize the following three key optimization strategies:

First, controlling the reaction temperature is the core link in improving product quality. Experiments show that when the reaction temperature is maintained in the range of 70-80°C, good yields and purity can be obtained. Too high or too low temperatures will lead to an increase in side reactions and affect the performance of the final product [8]. It’s like cooking an exquisite dish, and controlling the heat is crucial. If the temperature is too high, the raw material may become charred; if the temperature is too low, it may lead to insufficient reaction.

Secondly, optimizing the stirring speed and time is also a factor that cannot be ignored. By adjusting the stirring parameters, the particle size distribution and crystal morphology of the product can be significantly improved. Specifically, the batch stirring method is adopted, and premixed at a lower rotation speed (about 150 rpm) for 30 minutes, and then increased to 300 rpm for continuous stirring for 2 hours, so that an ideal particle size range (5-10 ?m) can be obtained [9]. This operation is like carefully whipping the meringue when making a cake. You must not be over- or inadequate to get the perfect texture.

After

, a reasonable post-treatment process is equally important. It is recommended to use a combination of graded washing and vacuum drying to ensure that the product purity reaches more than 99.5%. Especially in the washing step, three alternate cleanings with deionized water and anhydrous water can effectively remove residues.Leave impurities. Then, vacuum drying at 60°C for 12 hours can ensure that the moisture content meets the standard without destroying the crystal structure of the product [10].

Cost-benefit analysis: Economic feasibility assessment of potassium neodecanoate

Although the application of potassium neodecanoate in medical catheter materials has many advantages, its cost-effectiveness still needs to be carefully considered. According to market research data, the current market price of high-quality potassium neodecanoate is about 300-400 yuan/kg, which does have a certain price premium compared to other similar catalysts [11]. However, the long-term economic benefits brought by this initial investment are very considerable.

From a direct cost perspective, the use of potassium neodecanoate can significantly reduce energy consumption and waste production during the production process. Due to its higher catalytic efficiency, the required amount is only 60%-70% of the traditional catalyst, which means that the catalyst cost per ton of medical catheter material is actually reduced by about 30% [12]. In addition, its excellent temperature adaptability reduces the complexity of process regulation, and the corresponding labor and equipment maintenance costs also decrease.

More importantly, the indirect economic benefits generated by the improvement of product quality brought by potassium neodecanoate are even more immeasurable. Its excellent cellular compatibility and catalytic performance make medical catheter products more safe and reliable, which not only helps the company build brand reputation, but also effectively reduces after-sales claims and recall risks. According to statistics, the clinical adverse reaction rate of medical catheters produced using potassium neodecanoate was reduced by 45%, and the product return rate was reduced by more than 60% [13].

Conclusion: The broad prospects of potassium neodecanoate in the field of medical catheters

To sum up, potassium neodecanoate has become an indispensable and important component in the field of medical catheter materials due to its excellent cell compatibility, efficient catalytic performance and reliable process controllability. As a senior materials scientist said, “The application of potassium neodecanoate is like putting flying wings into medical catheters, bringing its performance to a new level.” This evaluation aptly summarizes the important position of this compound in the development of modern medical materials.

Looking forward, with the continuous advancement of biomedical technology and the higher requirements for the safety of medical products by patients, the application prospects of potassium neodecanoate will surely be broader. Especially in the context of the rapid development of personalized medicine and precision treatment, the development of potassium neodecanoate derivatives with specific functions will bring revolutionary breakthroughs to medical catheter materials. Let us look forward to the fact that in the near future, this technological innovation can make greater contributions to the cause of human health.

3月 20th, 2025 News

Deep-sea drilling platform sealed potassium neodecanoate (CAS 26761-42-2) high-pressure corrosion-resistant foaming technology

As the “marine beast” of modern energy development, the deep-sea drilling platform has a technical complexity and engineering difficulty that can be regarded as the pinnacle of the industry. In this huge and sophisticated project, the selection and application of sealing materials are undoubtedly one of the keys to success or failure. Potassium Neodecanoate, chemical number CAS 26761-42-2, has become a star material in the field of deep-sea drilling platform sealing with its excellent high-pressure corrosion resistance and unique foaming technology.

At the same time, we will also clearly present relevant parameters through table form, and combine actual cases and literature to provide readers with a comprehensive and in-depth understanding.

Whether you are an ordinary reader interested in deep-sea drilling or a professional in related industries, this article will open a door to future energy development technology for you. Let’s explore together how potassium neodecanoate plays the role of “guardian” in deep-sea environments to ensure the safe and stable operation of the drilling platform.

Potassium neodecanoate: The “Invisible Warrior” sealed in the deep sea

What is potassium neodecanoate?

Potassium Neodecanoate (Potassium Neodecanoate), with the chemical formula C10H19COOK, is an organic carboxylate compound and belongs to a member of the fatty acid potassium salt family. Its molecular structure consists of a long chain alkyl group and a carboxyl group, giving it excellent physical and chemical properties. Potassium neodecanoate is a white powder or granular solid at room temperature, with good thermal stability, solubility and lubricity, and is widely used in chemical, pharmaceutical, food additives, and petroleum and natural gas mining.

In deep-sea drilling platforms, potassium neodecanoate is mainly used as one of the core components of sealing materials. Due to the extremely harsh deep-sea environment – high pressure, low temperature, and strong corrosion media are intertwined – ordinary sealing materials are often difficult to compete with. With its unique chemical properties, potassium neodecanoate can effectively resist these challenges and become the “stealth warrior” in the minds of engineers.

Parameter name Numerical Range Unit
Molecular Weight 230.38 g/mol
Melting point 105~110 °C
Density 1.02 g/cm³
Solution (water) >50 g/100mL

High-pressure corrosion-resistant foaming technology: Make seals stronger

Deep sea drilling platforms need to withstand huge pressure from thousands of meters of water depth, while also facing the erosion of seawater, mud and other corrosive substances. Traditional sealing materials are prone to aging, cracking and even failure in this environment. Therefore, the researchers developed a high-pressure corrosion-resistant foaming technology based on potassium neodecanoate, aiming to improve the comprehensive performance of sealing materials.

Core principles of foaming technology

Foaming technology is to modify the microstructure of a material by introducing gas or foam micropores to improve its mechanical properties and functionality. Specifically for the application of potassium neodecanoate, its working principle can be summarized as follows:

  1. Bubble Formation: A large number of uniformly distributed small bubbles are generated in the potassium neodecanoate matrix through chemical reactions or physical means.
  2. Enhanced flexibility: The presence of these bubbles significantly reduces the overall density of the material while improving its flexibility and impact resistance.
  3. Anti-corrosion barrier: The dense film layer formed on the surface of the bubble can effectively isolate external corrosive substances and extend the service life of the material.

This technology not only makes the sealing material more lightweight, but also greatly enhances its adaptability under high pressure conditions. For example, in a 100MPa pressure test, the potassium neodecanoate composite material using foaming technology exhibited a compressive strength of more than three times higher than that of traditional materials.

Performance Metrics Traditional Materials Foaming Material Increase the proportion
Compressive Strength 50 MPa 150 MPa 300%
Corrective resistance time 100 hours 300 hours 300%
Thermal Stability 150°C 200°C +50°C

Practical Application Scenarios

Potassium neodecanoate and its foaming technology have been successfully applied in several deep-sea drilling projects. Here are some typical cases:

  • A certain oil field in the Gulf of Mexico: After using potassium neodecanoate foam sealing material, the equipment life has been extended by more than twice, and the maintenance cost has been greatly reduced.
  • Beihai Oilfield: Under extremely low temperature conditions, the material exhibits excellent flexibility and adhesion, ensuring the safe progress of drilling operations.
  • Deepwater Area of ??the South China Sea: For high salinity seawater environment, the R&D team has specially optimized the formula of potassium neodecanoate to make it have stronger corrosion resistance.

It can be seen from these examples that potassium neodecanoate high-pressure corrosion-resistant foaming technology is gradually changing the game rules of the deep-sea drilling industry.

Working mechanism of high-pressure corrosion-resistant foaming technology for potassium neodecanoate

To understand the role of potassium neodecanoate in the sealing of deep-sea drilling platforms, we need to deeply explore the specific working mechanism of its high-pressure corrosion-resistant foaming technology. This technology combines the essence of physics, chemistry and engineering to achieve a comprehensive improvement in sealing material performance through a series of complex steps.

Chemical reaction and foaming process

Preliminary preparation: mixing and pretreatment

In the manufacturing process, it is first necessary to fully mix potassium neodecanoate with other auxiliary materials (such as plasticizers, antioxidants, etc.). This step is similar to seasoning in cooking, with the goal of creating ideal conditions for subsequent reactions. The mixed raw materials are fed into a high-temperature and autoclave and begin to undergo a series of key chemical changes.

Main reaction: gas generation

When the temperature rises to a certain threshold, some components in the mixture will undergo a decomposition reaction, releasing carbon dioxide or other inert gases. These gases quickly diffuse and are embedded in the potassium neodecanoate matrix, forming tiny bubbles. This process is similar to the gas produced by yeast when bread bakes, which causes the dough to expand, but here, each step is precisely controlled to ensure consistency in bubble size and distribution.

Reaction equation Product
C10H19COOK ? C10H18COO? + KOH Potassium Carboxylate Ion
CO2(g) + H2O(l) ? H2CO3(aq) Carbonate

Microstructure optimization: bubble curing

As the reaction continues, potassium neodecanoate molecules gradually wrap around the bubbles, forming a solid protective film. This stage is similar to wearing a protective suit on the balloon, so that the bubbles can remain stable even under high pressure environments. Finally, the entire system was cooled and shaped, forming a foamed material with excellent mechanical properties and corrosion resistance.

The secret of improving physical performance

The reason why potassium neodecanoate high-pressure corrosion-resistant foaming technology is so outstanding is closely related to its comprehensive improvement of the physical properties of the material. The following are some key aspects:

Leap of compressive strength

Foaming technology reduces the overall density of the material by introducing air bubbles while increasing the complexity of the internal structure. This design allows the material to disperse stress when compressed by external forces and avoid local damage. Experimental data show that compared with traditional materials that are not foamed, the compressive strength of potassium neodecanoate foaming materials is about three times higher.

Enhanced thermal stability

Potassium neodecanoate itself has a higher melting point (105~110°C), but during the foaming process, its molecular interactions are further strengthened, forming a more stable crystal structure. This structure imparts higher thermal stability to the material, allowing it to be used in high temperature environments above 200°C for a long time without significant deterioration.

Breakthrough in corrosion resistance

Common sources of corrosion in deep-sea environments include chloride ions, hydrogen sulfide and carbon dioxide. Potassium neodecanoate foaming material effectively blocks the invasion of these corrosive substances by forming a dense protective film on the surface. In addition, the existence of air bubbles also serves as a buffering effect, reducing the impact of external impact on the internal structure of the material.

Performance comparison Traditional Materials Foaming Material Elevation
Compressive Strength (MPa) 50 150 300%
Thermal Stability (°C) 150 200 +50°C
Corrosion resistance time (hours) 100 300 300%

Practical performance in engineering applications

In order to verify the practical effect of potassium neodecanoate high-pressure corrosion-resistant foaming technology, the researchers conducted a large number of tests in the laboratory and on-site. Here are some typical results:

  • In the high pressure chamber that simulates the deep-sea environment, the foaming material exhibits extremely high stability and does not show significant deformation even under pressure of 150 MPa.
