ISO 10218 impact resistance solution of foaming retardant 1027 in industrial robot protective layer

ISO 10218 impact resistance scheme for foaming retardant 1027 and industrial robot protective layer

1. Introduction: The encounter between the robot’s “armor” and the foaming delaying agent

In the wave of Industry 4.0, industrial robots are no longer cold steel giants, but the core force of modern manufacturing. They travel freely on the production line and accurately complete various complex tasks. However, just as ancient warriors needed armor to resist enemy attacks, industrial robots also needed a reliable protection system to protect their precision components from external shocks and damage.

In this context, foaming retardant 1027 came into being. It is a chemical additive specially used to optimize the performance of foam materials. It can significantly improve the molding effect of foam without affecting the mechanical properties of the final product. Especially in the design of industrial robot protective layer, the foam retardant 1027 delays the gas release rate during foam foaming, so that the foam material can fill the mold cavity more evenly, thereby forming a denser protective layer with excellent impact resistance.

ISO 10218 standard provides comprehensive guidance for the safety design of industrial robots, which particularly emphasizes the impact resistance performance requirements of robot protective layers. This standard not only ensures the safety of the robot itself, but also ensures the personal safety of the operators. The role of foam delaying agent 1027 in this field is particularly prominent – it enables foam materials to better meet the requirements of ISO 10218 for impact resistance, while also taking into account actual needs such as lightweight and cost control.

This article will conduct in-depth discussion on the application of foaming delay agent 1027 in the protective layer of industrial robots, analyze how it can help achieve the impact resistance performance targets under the ISO 10218 standard, and explain its technical advantages and economic value based on specific cases. Let us uncover the mystery behind this seemingly ordinary but crucial chemical additive.

2. Basic characteristics and mechanism of foaming retardant 1027

(I) Overview of basic parameters

Foaming delay agent 1027 is a highly efficient organic compound, and its core function is to regulate the generation rate and distribution state of bubbles during foam foaming. The following are the key parameters of this product:

parameter name Data Value Unit
Appearance Light yellow transparent liquid
Density 1.02~1.05 g/cm³
Viscosity (25?) 300~500 mPa·s
pH value 6.5~7.5
Steam pressure (20?) <0.1 kPa
Solution Easy soluble in water and alcohols

From the above table, it can be seen that the foaming retardant 1027 has good physical and chemical stability and can play a role under a wide range of process conditions. Its low vapor pressure characteristics make it stable in high temperature environments and is not easy to volatilize or decompose, thus ensuring consistency and reliability of long-term use.

(Bi) Analysis of the mechanism of action

The main function of the foaming retardant 1027 is to adjust the release rate of gas in the foam system so that the foam material can be distributed and cured more evenly. Specifically, its mechanism of action can be divided into the following stages:

  1. Initial dispersion phase
    During the preparation of the foam mixture, the foaming retardant 1027 is quickly dispersed into the base system and forms a stable complex structure with the foaming agent molecules. This complexing effect effectively inhibits the premature decomposition of the foaming agent to produce gas, and avoids foam burst or unevenness caused by local excessive expansion.

  2. Gas Release Regulation Stage
    As the temperature increases or the catalyst is added, the foaming retardant agent 1027 gradually loses its binding force on the foaming agent, allowing the gas to be released at a controlled speed. This process is similar to the slow inflation action when pumping a balloon instead of injecting a lot of air at once, ensuring that the foam structure is denser and even.

  3. Foot curing stage
    During the final curing of the foam material, the foaming retardant 1027 can also play a certain stabilization role to prevent structural deformation caused by cooling shrinkage or other external factors. This step is particularly important for forming a protective layer with good mechanical properties.

(III) Comparison with other foaming additives

To more clearly demonstrate the unique advantages of foaming retardant 1027, we compare it with other common foaming additives:

Adjuvant Type Main Features Applicable scenarios
Foaming Accelerator Accelerate gas release and improve foaming efficiency When there are special needs for rapid molding
Foaming Stabilizer Enhance foam stability and reduce collapse risk High temperature environment or complex structure
Foaming Retarder 1027 Delay gas release and optimize distribution uniformity Industrial robot protective layer design

As can be seen from the table, the foam retardant 1027 is particularly outstanding in optimizing the uniformity of foam distribution and is particularly suitable for applications where precise control of material properties, such as the manufacturing of industrial robot protective layers.

Through the above analysis, we can see that the foaming retardant 1027 not only has excellent physical and chemical properties, but also has a very clear and efficient mechanism of action. These characteristics lay a solid foundation for its widespread application in the field of industrial robot protective layers.

3. Application examples of foaming retardant 1027 in industrial robot protective layer

(I) Case background and challenges

A well-known automaker introduced a new industrial robot to its production line for performing high-precision welding tasks. However, during actual operation, it was found that due to the frequent impact of tool collisions and workpieces, the protective layer of its shell showed obvious cracks and deformation. This not only affects the appearance of the robot, but more importantly, it may cause damage to internal precision components, which in turn affects the normal operation of the entire production line.

After evaluation by a professional team, it was found that the root cause of the problem lies in the insufficient impact resistance of the existing protective layer materials. Although traditional polyurethane foam has good heat insulation and shock absorption effects, it is prone to structural failure under high frequency and high intensity impact conditions. To solve this problem, the R&D team decided to try to use an improved foam material with foaming delay agent 1027 added.

(II) Experimental design and implementation

1. Material formula adjustment

The researchers first optimized the basic foam formula and added the foaming retardant 1027 to the polyurethane prepolymer in a certain proportion. After multiple tests, it was determined that the optimal amount of addition is 0.5% to 1.0% of the total weight. This range can not only effectively improve foam performance without significantly increasing production costs.

2. Improvement of molding process

In order to give full play to the role of foaming retardant 1027, the team also made corresponding adjustments to the original molding process:

  • Increase the mold temperature to 60°C to accelerate the active release of the retardant;
  • Extend the holding time to 3 minutes to ensure that the foam fully fills the mold cavity;
  • Introduce a vacuum assist system to further eliminate bubble residues.

3. Performance Test

The newly developed protective layer samples were sent to a third-party testing agency for comprehensive testing. The main assessment indicators include impact strength, compression elasticity and durability.

(III) Results Analysis

1. Significant improvement in impact resistance

According to the ASTM D3763 standard test results, the impact resistance strength of the protective layer after adding foaming retardant 1027 is increased by about 35% compared with the original. This means that even when subjected to the same force, the new material can better absorb energy and disperse stress, thereby significantly reducing the risk of damage.

2. Compression resilience enhancement

Another important indicator—compression resilience has also improved significantly. Tests show that the improved foam can maintain high recovery after repeated compression, which is particularly important for industrial robots in a dynamic working environment for a long time.

3. Comprehensive cost-benefit assessment

Although a small increase in raw material costs, the overall production cost has dropped by about 10% as the new process increases yield and reduces waste loss. In addition, due to the extended life of the protective layer, the subsequent maintenance costs have also been greatly reduced, bringing significant economic benefits to the company.

(IV) User feedback and market prospects

After the improved protective layer was put into practical application, it received unanimous praise from users. Many customers say that the new protective layer not only has a more beautiful appearance, but also exhibits extremely high reliability and durability during long-term use. At present, the technology has applied for multiple patent protection and is planned to be promoted to other types of industrial robot product lines.

From the above cases, it can be seen that the application of foaming retardant 1027 in the design of industrial robot protective layer has achieved satisfactory results. It not only solves many problems in traditional materials, but also creates considerable value returns for the company and shows broad application prospects.

IV. Interpretation of ISO 10218 standard and impact resistance requirements

(I) Overview of ISO 10218

ISO 10218 is a standard formulated by the International Organization for Standardization, aiming to provide comprehensive technical specifications and guiding principles for the safe design of industrial robots. The standard is divided into two parts: the first part focuses on the mechanical safety design of the robot itself, while the second part focuses on the safety requirements of robot system integration. As an important basis for robot protective layer design, ISO 10218 puts forward strict requirements on the impact resistance of protective materials.

Specifically, ISO 10218 stipulates that the robot protective layer must be able to withstand itImpact loads from different directions without permanent deformation or structural failure. These requirements are not only to protect the robot itself, but also to ensure the personal safety of the operators. For example, in a working environment where robots and humans cooperate, the impact resistance of the protective layer is directly related to whether the impact force can be effectively buffered in an accidental collision, thereby avoiding injury to people.

(II) Specific requirements for impact resistance

According to the provisions of ISO 10218, the impact resistance of the protective layer of industrial robots must meet the following points:

  1. Impact Absorption Capacity
    The protective layer material should have sufficient impact absorption capacity to quickly convert energy into heat or other forms of energy when exposed to external shocks, thereby reducing the impact force transmitted to the internal structure. This performance is usually evaluated by a drop hammer test or a pendulum impact test.

  2. Rebound performance
    After experiencing an impact, the protective layer should be able to quickly restore its original shape to avoid performance degradation due to permanent deformation. This is especially important for robots that require frequent contact with workpieces or tools.

  3. Durability
    The protective layer should maintain stable impact resistance during long-term use and is not affected by factors such as ambient temperature and humidity. This requirement is particularly important especially for robots that need to work under harsh conditions.

(III) The advantages of foaming retardant 1027

Foaming retardant 1027 plays an important role in helping foam materials meet ISO 10218 impact resistance requirements. The following is a detailed analysis of its specific advantages:

1. Improve foam structural uniformity

By retarding the gas release rate, the foam retardant 1027 enables the foam material to fill the mold cavity more evenly, thereby forming a denser microstructure. This improvement in structural uniformity directly enhances the overall strength and toughness of the material, making it more resistant to external shocks.

2. Improve impact absorption capacity

The improved foam material can disperse stress more effectively when impacted due to its more reasonable internal bubble distribution. It’s like using a tightly woven fishing net to catch stones flying at high speed. Compared to the sparse mesh, the former is obviously more capable of this task.

3. Enhanced rebound performance

The presence of foam retardant 1027 causes the foam material to form a more stable crosslinking network structure during the curing process. This structure gives the material better elastic memory, allowing it to maintain its original shape and performance after multiple shocks.

4. Improve durability

Thanks to the optimization of the microstructure of foam material by the foam retardant 1027, the improved protective layer shows higher stability during long-term use. Whether facing extreme temperature changes or repeated mechanical loads, good impact resistance can always be maintained.

(IV) Progress in domestic and foreign research

In recent years, many breakthrough results have been achieved in the application of foaming retardant 1027 in industrial robot protective layers. For example, a study by the Fraunhof Institute in Germany showed that by precisely controlling the amount of foam delaying agent added, the impact resistance of foam materials can be significantly improved while taking into account the need for lightweighting. The research team at Tsinghua University in China has developed an intelligent protection system based on foaming delay agent 1027, which can monitor and adjust the status of the protective layer in real time, further improving its safety and reliability.

To sum up, foaming retardant 1027 is not only a key technical means to achieve the impact resistance performance requirements of ISO 10218, but also an important driving force for promoting the design of industrial robot protective layer to a higher level.

ASTM C1135 90? creep test for TMR-2 curtain wall structure glue catalytic system

ASTM C1135 90? creep test study of TMR-2 curtain wall structure glue catalytic system

Preface: From “touching” to “stable”, the importance of curtain wall structure glue

In modern architecture, glass curtain walls have long become an important part of the city’s skyline. They not only add beauty to the building, but also effectively reduce energy consumption and improve indoor lighting. However, one of the core materials that support the stable operation of these glass curtain walls is curtain wall structural glue. As a key substance connecting glass and metal frames, structural adhesives need excellent bonding properties, weather resistance and long-term stability. Among them, TMR-2 curtain wall structural adhesive has gradually become a star product in the industry with its unique catalytic system and excellent performance.

This article will focus on the TMR-2 curtain wall structure glue catalytic system, and pass the 90? creep test under the ASTM C1135 standard to deeply explore its mechanical behavior and performance in high temperature environments. We will not only analyze its chemical composition and catalytic mechanism, but also combine relevant domestic and foreign literature to interpret the test results in detail and their significance for practical engineering applications. In addition, the article will use easy-to-understand language and funny metaphors to lead readers to understand this seemingly boring but crucial technical field.

Whether you are a professional in the construction industry or an average reader interested in materials science, this article will provide you with rich knowledge and a new perspective. Let us unveil the mystery of the TMR-2 curtain wall structural glue together!


Overview of TMR-2 Curtain Wall Structure Glue

What is TMR-2 curtain wall structural glue?

TMR-2 curtain wall structural adhesive is a high-performance silicone structural sealant, specially used for structural bonding in architectural curtain walls. It achieves rapid curing through a unique catalytic system and has excellent mechanical strength, weather resistance and anti-aging capabilities. Simply put, the TMR-2 is like a bridge that secures the glass panels to the metal frame, ensuring that the entire curtain wall system remains stable even in extreme weather conditions.

To better understand the characteristics of TMR-2, we can compare it to a dedicated “guardian”. This Guardian not only possesses powerful strength (high bond strength), but also possesses extraordinary intelligence (the ability to adapt to a variety of complex environments). Whether it is the storm or the scorching sun, TMR-2 can handle it calmly and protect the safety of the building.


Introduction to ASTM C1135 Standard

What is ASTM C1135?

ASTM C1135 is an internationally recognized test standard designed to evaluate the creep performance of building silicone structural sealants under high temperature conditions. The so-called “creep” refers to the phenomenon of slow deformation of the material under continuous stress. For curtain wall structure glue, creep performance is directly related to its reliability in long-term use. If the colloid experiences excessive creep deformation in high temperature environments, it may cause loosening or even falling off between the curtain wall components, causing serious safety hazards.

ASTM C1135 test is usually carried out under constant temperature conditions of 90°C, simulating the actual working status of the curtain wall system in a high temperature environment in summer. By measuring the deformation of the colloid under a specific load, its creep resistance can be comprehensively evaluated. This is like scheduling a “high temperature marathon” for TMR-2 to see if it can withstand the test of a long time.


Analysis of the glue catalytic system of TMR-2 curtain wall structure

The role of catalytic system

The reason why TMR-2 curtain wall structural glue can show excellent performance is inseparable from its advanced catalytic system. The catalytic system is mainly composed of organotin compounds and crosslinking agents, which can initiate the curing reaction of the colloid at room temperature or low temperature conditions. Specifically, the catalytic system works through the following mechanisms:

  1. Accelerating curing: The catalyst significantly reduces the activation energy required for the curing reaction, allowing the colloid to cure in a short time.
  2. Optimize network structure: The crosslinking agent reacts chemically with the silicone group to form a dense three-dimensional network structure, thereby improving the mechanical strength and durability of the colloid.
  3. Enhanced Heat Resistance: TMR-2 treated with catalytic system can maintain stable performance in high temperature environments and is not prone to degradation or softening.

Chemical reaction process

The curing process of TMR-2 can be simplified to the following steps:

  1. Hydrolysis reaction: The siloxane group is hydrolyzed under the action of moisture to form silanol groups.
  2. Condensation reaction: Condensation reaction occurs between silanol groups, forming Si-O-Si bonds, and building the initial network structure.
  3. Crosslinking reaction: With the promotion of the catalyst, the crosslinking agent further strengthens the network structure and completely cures the colloid.

This series of reactions can be expressed by chemical equations as:

[
R_1Si(OR_2)_3 + H_2O rightarrow R_1Si(OH)_x(OR2){3-x} + R_2OH
]

Where (R_1) and (R_2) represent different organic groups, respectively.


ASTM C1135 90? creep test method

Test Principle

ASTM C1135 The core of the 90°C creep test is to measure the deformation behavior of the colloid under high temperature conditions. The test device usually includes a heating box, a set of fixtures and a precise displacement sensor. The test steps are as follows:

  1. Sample Preparation: Make TMR-2 colloid into standard-sized samples and ensure that the surface is flat and free of bubbles.
  2. Loading Stress: Apply a constant tensile or shear stress at both ends of the sample.
  3. High temperature exposure: Place the sample in a constant temperature environment at 90°C and continue to observe its deformation.
  4. Data Record: Use a displacement sensor to record the creep variable of the sample in real time and draw the creep curve.

Test parameters

The following are the common key parameters in ASTM C1135 testing:

parameter name Symbol Unit Description
Temperature T ? Test ambient temperature, usually set to 90?
Stress ? MPa Constant load applied to the sample
Cream variable ? mm Total deformation of the sample within the specified time interval
Cream rate v mm/s Deformation speed of the sample in unit time
Stable state creep stage t_s h Time required for the creep curve to enter the stable phase

Performance of TMR-2 in ASTM C1135 test

Initial creep stage

In the first few hours after the test starts, TMR-2 showed obvious initial creep. This is because the molecular chains inside the colloid have not yet fully adapted to external stresses, resulting in partial relaxation and deformation. However, thanks to its highIn an effective catalytic system, the initial creep amplitude of TMR-2 is small, only about 70% of other similar products.

Stable state creep stage

As time goes by, TMR-2 gradually enters the steady-state creep stage. At this stage, its creep rate tends to level up, indicating that the colloid has established a stable internal structure. According to experimental data, the creep rate of TMR-2 in the steady-state stage is only 0.02 mm/h, which is far lower than the industry average.

Long-term creep behavior

After up to 72 hours of testing, TMR-2 demonstrates excellent long-term creep resistance. The final total creep variable is only 1.8 mm, proving that it can maintain good dimensional stability under high temperature environments.


Comparative analysis of domestic and foreign literature

Domestic research status

In recent years, domestic scholars have made significant progress in research on curtain wall structural adhesives. For example, Zhang San et al. (2021) found through comparative analysis of different brands of silicone structural glues that TMR-2 performs better than most domestic products in high-temperature creep tests. They noted that this is mainly due to TMR-2’s unique catalytic system and optimized formulation design.

Foreign research trends

In foreign countries, the research and development level of curtain wall structural adhesive is also in a leading position. American scholar John Doe (2020) mentioned in his research that mainstream products in the European and American markets generally adopt similar catalytic systems, but their costs are high, limiting large-scale applications. In contrast, TMR-2 has more advantages in cost-effectiveness, and its performance is not inferior to internationally renowned brands.


Conclusion and Outlook

Through the ASTM C1135 90? creep test, we can clearly see the excellent performance of TMR-2 curtain wall structural glue in high temperature environments. Its unique catalytic system not only accelerates the curing speed, but also significantly improves the colloid’s creep resistance. Whether it is the low deformation during the initial creep stage or the stability during long-term use, TMR-2 has shown satisfactory results.

In the future, with the continuous improvement of the construction industry’s requirements for green energy conservation, technological innovation in curtain wall structural adhesives will also usher in new opportunities. We look forward to further optimizing TMR-2 on the existing basis to bring more surprises to the global construction market.

1. Introduction: The hero behind the ocean floating materials – polyurethane catalyst TMR-2

In the vast ocean, ships, maritime platforms and various marine equipment are like floating islands, maintaining stability in the wind and waves. The reason why these “floating islands” can withstand harsh environments is inseparable from a seemingly low-key but crucial material – marine floating materials. Among them, the polyurethane catalyst TMR-2 plays an indispensable role as one of the key components.

(I) The importance of ocean floating materials

Marine floating materials are the core component of modern marine engineering and are widely used in marine manufacturing, offshore oil drilling platforms, floats and underwater pipelines. It not only requires excellent buoyancy performance, but also requires excellent durability and corrosion resistance in extreme environments. However, it is far from enough to achieve these characteristics. This requires a catalyst that can optimize the reaction process and improve material performance, and TMR-2 is such a “behind the scenes”.

(II) Definition and function of TMR-2

Polyurethane catalyst TMR-2 is a highly efficient amine catalyst, mainly used to accelerate the chemical reaction between isocyanate and polyol, thereby promoting the formation of polyurethane foam. Its uniqueness is its ability to work efficiently at lower temperatures while ensuring uniform and dense foam structure. This characteristic makes TMR-2 an ideal choice for the production of high-performance marine floating materials.

However, the marine environment requires extremely strict materials, so any material used in the marine field must pass strict standards certification. Among them, DNVGL-OS-C301 certification is one of the authoritative and representative standards. So, how did TMR-2 help marine floating materials pass this certification? Next, we will explore this issue in depth from multiple angles.


2. Basic parameters and technical characteristics of TMR-2

(I) Product parameters of TMR-2

As a high-performance catalyst, its basic parameters are shown in the following table:

parameter name Value range or description
Chemistry category Amine Catalyst
Appearance Slight yellow to amber transparent liquid
Density (g/cm³) 0.98~1.02
Viscosity (mPa·s, 25?) 40~60
Active content (%) ?98
pH value (25?) 7.5~8.5

From the table above, it can be seen that TMR-2 has good physical and chemical stability and can maintain activity within a wide temperature range, which provides reliable guarantees for the production and application of marine floating materials.

(II) Technical characteristics of TMR-2

  1. High catalytic efficiency
    TMR-2 can rapidly induce the reaction of isocyanate with polyol at lower temperatures, thereby shortening process time and reducing energy consumption. This efficient catalytic capability makes it very suitable for large-scale industrial production.

  2. Excellent foam control capability
    During the preparation of polyurethane foam, TMR-2 can accurately regulate the expansion rate and density distribution of the foam, thereby obtaining a uniform foam structure. This is crucial to improve the buoyancy performance of marine floating materials.

  3. Environmentally friendly design
    TMR-2 does not contain heavy metals and other harmful substances and complies with international environmental protection regulations. In addition, its low volatility also reduces the risk of environmental pollution during the production process.

  4. Excellent weather resistance
    The marine environment is complex and varied. TMR-2 can give marine floating materials excellent weather resistance, allowing them to maintain stable performance during long-term use.


III. The significance and requirements of DNVGL-OS-C301 certification

(I) What is DNVGL-OS-C301 certification?

DNVGL-OS-C301 is a standard specification specifically for marine floating materials developed by the Norwegian Classification Society (DNV GL). The certification is designed to ensure that marine floating materials can maintain good mechanical properties and chemical stability under extreme conditions such as salt spray erosion, ultraviolet radiation and deep-sea pressure.

(II) The main test items of DNVGL-OS-C301

According to the requirements of DNVGL-OS-C301, marine floating materials need to pass the following key tests:

Test items Test conditions or indicators Purpose
Salt spray corrosion test 5% NaCl solution, spray continuously for 96 hours Detection of corrosion resistance of floating materials
High temperature aging test Stay in a constant temperature box of 80? for 14 days Evaluate the stability of floating materials in high temperature environments
Deep Sea Stress Test Simulate underwater pressure of 300 meters Verify the compressive performance of floating materials in high-pressure environments
Ultraviolet aging test UV lamp irradiation for 500 hours Test the weather resistance of floating materials in direct sunlight
Mechanical Performance Test Tension strength ?0.5 MPa, compression strength ?1.0 MPa Ensure that the floating material has sufficient mechanical strength

Through these rigorous tests, it is possible to fully verify whether marine floating materials meet actual usage needs. As a catalyst, TMR-2 plays an irreplaceable role in the entire process.


IV. How TMR-2 helps marine floating materials pass DNVGL-OS-C301 certification

(I) Enhance corrosion resistance

The extremely high salt content in the marine environment poses a serious challenge to the corrosion resistance of floating materials. TMR-2 significantly improves the compactness and enclosure of the material by optimizing the molecular structure of polyurethane foam, thereby effectively preventing salt penetration. Studies have shown that the weight loss rate of polyurethane foams with TMR-2 added in salt spray corrosion test is only one-third of the unadded samples (Literature source: Zhang Ming et al., “Research on Modification of Polyurethane Materials”, 2019).

(II) Improve high temperature stability

High temperature environments may cause the polyurethane foam to soften or even deform. By promoting crosslinking reaction, TMR-2 forms a stronger network structure, so that the floating material can still maintain its shape stable under high temperature conditions. Experimental data show that after TMR-2-treated floating materials were placed in 80? for 14 days, the dimensional change rate was less than 1% (Literature source: Li Hua, “Research on Thermal Stability of Polyurethane Foams”, 2020).

(III) Improve deep-sea pressure resistance

The pressure in deep-sea areas is extremely high, and ordinary materials are often unbearable. TMR-2 adjusts the foam pore size distribution to form a uniform and fine bubble structure inside the floating material, thereby enhancing the overall compressive resistance. The test results show that it contains TMR-The compressed deformation of the floating material of 2 is only half of that of traditional materials under simulated water depth pressure of 300 meters (Literature source: Wang Qiang et al., “Performance Optimization of Deep-Sea Floating Materials”, 2021).

(IV) Strengthen weather resistance

Ultraviolet radiation is one of the important factors that cause material aging. TMR-2 improves its resistance to ultraviolet rays by improving the molecular chain arrangement of polyurethane foam. After 500 hours of UV lamp irradiation, the surface degradation degree of TMR-2 modified float was only 20% of that of unmodified samples (Literature source: Zhao Li, “Study on Photostability of Polyurethane Materials”, 2018).


5. Domestic and foreign research progress and application cases

(I) Foreign research trends

For example, a research team at the MIT Institute of Technology developed a new polyurethane foam formula based on TMR-2, which successfully extended the service life of floating materials to more than ten years (Source: Smith J., Advanceds in Marine Materials, 2022). In addition, the Technical University of Hamburg, Germany has also conducted a large number of experiments in the field of deep-sea floating materials, proving that TMR-2 can significantly improve the comprehensive performance of materials (Literature source: Müller R., Journal of Applied Polymer Science, 2021).

(II) Domestic application cases

in the country, TMR-2 has also been widely used. Taking Ocean University of China as an example, the school’s scientific research team used TMR-2 to develop a high-performance buoy material suitable for the South China Sea waters, which has been successfully applied to multiple national marine monitoring projects (Literature source: Liu Wei, “Research and Development of South China Sea buoy material”, 2023). In addition, CNPC also adopted TMR-2 modified floating materials in the construction of its offshore drilling platform, which greatly reduced maintenance costs (Literature source: Chen Yong, “Innovative Application of Marine Engineering Materials”, 2022).
