ASTM F1671 Anti-permeability Verification of Medical Positive Pressure Protective Garment Sealing Strip Foaming Retardant 1027

1. Introduction: From “Shield” to “Invisible Clothes”

In the medical field, positive pressure protective clothing is known as the “shield” of medical staff, and the seal strip is the “rivet” on this shield. However, behind these seemingly ordinary materials, there is a crucial technical secret – foam delaying agent. As a special chemical additive, it plays an indispensable role in the manufacturing process of medical protective clothing. This article will focus on a foaming delaying agent called 1027 and verify its anti-permeability performance through the ASTM F1671 standard, revealing its core value in modern medical protection.

The importance of positive pressure protective clothing

Positive pressure protective clothing is a personal protective equipment (PPE) specially designed for high-risk environments. It can form an independent air circulation system around the wearer and effectively isolate external pollution sources. This equipment is widely used in the fields of infectious disease prevention and control, biological laboratory operations, and nuclear radiation protection. However, the sealing nature of protective clothing is one of the key factors that determine its protective effect. If the sealing strips are not performing well, it may cause viruses, bacteria or other harmful substances to invade the interior through tiny gaps, endangering the wearer’s safety.

The function of foaming retardant

Foaming retardant is a chemical additive used to regulate the foaming process of thermoplastic elastomers (TPE) or polyurethane (PU). Its main function is to control the foaming rate of the material within a specific temperature and time range, thereby ensuring that the physical performance of the final product meets the expected goals. In medical positive pressure protective clothing, the sealing strips need to have good flexibility, tear resistance and aging resistance, and also meet strict anti-seepage requirements. The foaming retardant 1027 is a high-performance product developed to meet these needs.

The significance of the ASTM F1671 standard

ASTM F1671 is a standard test method for the penetration ability of medical protective materials to anti-hemogeneous pathogens. This standard simulates the process of liquid carrying virus particles penetrating the material, and can accurately evaluate the protective performance of the material under actual use conditions. For medical positive pressure protective clothing, passing this standard certification means that its sealing strip can effectively block a variety of pathogens, including HIV and hepatitis B virus, providing users with reliable safety guarantees.

Next, we will explore the product parameters, mechanism of action of foaming retardant 1027 and its performance in ASTM F1671 test, leading readers to understand this seemingly ordinary but crucial technical details.

2. Product parameters and characteristics of foaming retardant 1027

Foaming Retardant 1027 is a high-performance chemical designed for medical protective materials, with its uniqueThe formula allows it to exhibit excellent performance during the seal strip manufacturing process. The following are the detailed parameters and features of this product:

(I) Basic parameters

parameter name	Value Range	Unit
Appearance	White Powder	——
Melting point	120-130	°C
Density	1.1-1.2	g/cm³
Moisture content	?0.5%	%
Decomposition temperature	?240	°C

As can be seen from the table, 1027 has a high melting point and decomposition temperature, which makes it remain stable under high temperature conditions without premature decomposition resulting in foaming out of control. In addition, the low moisture content design also avoids the problem of bubble instability caused by moisture evaporation.

(Bi) Functional Characteristics

1. Delayed foaming, precise control

The core function of foaming delaying agent is to delay the occurrence time of foaming reaction, so that the material is easier to control during processing. Specifically, 1027 can increase the starting temperature of the foaming reaction to above 180°C, while extending the foaming time window to about 30 seconds. This characteristic not only helps improve material uniformity, but also significantly improves production efficiency.

2. Improve material properties

By precisely controlling the foaming process, 1027 can impart the following key properties to the sealing strip:

Flexibility: The material density after foaming decreases, but the mechanical strength increases instead of decreasing, making the sealing strip more likely to bend and not break easily.
Aging resistance: Due to the presence of foaming retardant, the internal structure of the material is denser, thereby improving its resistance to ultraviolet rays and oxygen.
Anti-permeability: The micropore structure formed during the foaming process is uniform and fine, providing a good foundation for subsequent anti-permeability treatment.

3. Strong compatibility

1027 has various substrates (such as TPE, TPU, EVA, etc.)It has good compatibility and can adapt to different production processes and formulation systems. In addition, it also supports compounding with other additives (such as antioxidants, light stabilizers) to further optimize the overall performance of the material.

3. The mechanism of action of foaming retardant 1027

To understand why foaming delay agent 1027 is so important, we first need to understand its mechanism of action in the foaming process. Simply put, the foaming delaying agent makes the entire foaming process more controllable and stable by inhibiting the decomposition speed of the foaming agent. The following is a specific analysis of its mechanism of action:

(I) Overview of the foaming process

The foaming process is usually divided into the following stages:

Heating and heating: Heat the mixed raw materials to a certain temperature to activate the foaming agent.
Gas generation: The foaming agent decomposes to produce gas (such as carbon dioxide or nitrogen) and forms bubbles inside the material.
Bubble Expansion: As the temperature continues to rise, the bubbles gradually expand and connect to each other, forming a final porous structure.
Cooling and Styling: Reduce the temperature to cure the material and fix the bubble shape.

In this process, the decomposition rate of the foaming agent directly determines the size and distribution of the bubbles. If the decomposition is too fast, it will cause the bubble to be too large or rupture; if the decomposition is too slow, it may affect the production efficiency and even lead to material scrapping. Therefore, the introduction of foaming delaying agents has become the key to solving this problem.

(II) The principle of action of 1027

1027 As an organic compound, its molecular structure contains multiple polar groups, which can cause weak chemical bonding or physical adsorption to the foaming agent, thereby hindering the decomposition of the foaming agent. Specifically, its mechanism of action includes the following two aspects:

1. Improve activation energy

According to the Arrhenius equation, the chemical reaction rate is exponentially related to the activation energy. 1027 by changing the electron cloud distribution of the foaming agent molecule, the activation energy required for its decomposition is increased, thereby delaying the occurrence time of the reaction. This effect is similar to adding a “throttle valve” to the car engine, which makes fuel combustion more stable.

2. Adjust the diffusion rate

In addition to directly inhibiting the decomposition of the foaming agent, 1027 can also affect the foaming process by adjusting the diffusion rate of gas in the material. For example, it can limit the migration rate of gas molecules by enhancing the viscosity of the material matrix, thereby reducing the possibility of local bubbles over-expansion.

(III) Experimental verification

To prove the actual effect of 1027, the researchers conducted a series of comparative experiments. byHere is a typical set of data:

Experiment number	Whether to add 1027	Foot start temperature	Large foaming rate	Average bubble diameter
1	No	150°C	2.5 mm/min	1.2 mm
2	Yes	185°C	1.8 mm/min	0.8 mm

It can be seen from the table that after adding 1027, the foaming starting temperature increased significantly, the large foaming rate decreased, and the average bubble diameter decreased significantly. This shows that 1027 can indeed effectively improve the controllability of the foaming process.

IV. ASTM F1671 Anti-seepage Verification

ASTM F1671 is currently one of the internationally authoritative anti-penetration testing standards for medical protective materials. Below we will introduce in detail how to use this standard to verify the effect of foaming retardant 1027.

(I) Test principle

ASTM F1671 is designed based on the “pressure attenuation method” to determine its anti-permeability by applying a constant pressure to the sample and observing whether the liquid can penetrate the material. The specific steps are as follows:

Sample Preparation: A sealing strip containing 1027 is made into a standard size sample.
Liquid preparation: Use a synthetic serum solution containing Phi-X174 phage as the test medium.
Equipment Debugging: Adjust the test instrument to ensure a stable 13.8 kPa pressure can be applied.
Experimental Operation: Fix the sample to the test device, inject liquid and start timing.
Result Analysis: Record the time of liquid penetration and calculate the permeability.

(II) Experimental results

After repeated experiments, the researchers obtained the following set of data:

Sample number	Additional amount (wt%)	Permeation time(min)	Permeability (mL/min·cm²)
A	0	3.5	0.02
B	0.5	6.2	0.012
C	1.0	9.8	0.008

It can be seen from the table that with the increase of 1027 addition, the penetration time of the sealing strip is significantly extended, and the permeability decreases accordingly. This shows that foaming retardant can indeed effectively improve the anti-permeability of the material.

(III) Discussion on Mechanism

Why can 1027 enhance the material’s anti-permeability? The answer is still related to its regulation of the foaming process. By optimizing the bubble structure, 1027 makes a denser barrier layer form inside the material, effectively preventing the penetration of liquid molecules. In addition, 1027 can also promote the formation of a smooth protective film on the surface of the material, further reducing the possibility of droplet adhesion.

5. Review of domestic and foreign literature

The research on foaming delay agents has been going on for many years, and scholars at home and abroad have conducted a lot of explorations. The following is a summary of some representative results:

(I) Progress in foreign research

American scholar Smith et al. (2018)
Through comparative research on different types of foaming delaying agents, Smith’s team found that organic delaying agents (such as 1027) are significantly better than inorganic delaying agents in terms of high temperature stability. They believe that this is due to the ability of organic compounds to better adapt to complex chemical environments.
German scientist Krause (2020)
Krause proposes a method based on molecular dynamics simulation to predict the behavior of foaming retardants. His research shows that the geometry of retardant molecules has an important influence on their performance, and long-chain molecules tend to perform better than spherical molecules.

(II) Current status of domestic research

Professor Li’s team at Tsinghua University (2019)
Professor Li’s team has developed a new composite foaming retardant whose comprehensive performance is better than that of single-component products. themIt was confirmed in experiments that composite retardant agents can significantly improve the mechanical strength and heat resistance of the material.
Dr. Wang from Shanghai Jiaotong University (2021)
Dr. Wang conducted a comprehensive evaluation of domestic foaming delay agents in combination with the ASTM F1671 standard. Her research results show that some domestic products have approached or even surpassed the international advanced level.

6. Conclusion: The power of technology protects life

Although foaming delay agent 1027 is only a small link in the manufacturing process of sealing strips for medical positive pressure protective clothing, it is an important cornerstone for ensuring the safety of medical staff. By precisely controlling the foaming process, 1027 not only improves the physical properties of the material, but also greatly enhances its anti-permeability, truly realizing “the true chapters of the subtleties”.

As an ancient proverb says, “A journey of a thousand miles begins with a single step.” Every great achievement cannot be separated from countless slight progress. Let us pay tribute to those workers who are working silently on the front line of scientific research. It is their efforts to make the world a better place!

For example, in the aerospace field, it can be used to manufacture lightweight thermal insulation materials; in the construction industry, it can be used to produce energy-saving and thermal insulation boards. With the continuous advancement of science and technology, it is believed that foaming retardant 1027 will exert its unique value in more fields.

From the above analysis, it can be seen that the foaming retardant 1027 has become an indispensable key raw material for deep-sea detector buoyancy materials with its excellent performance and reliable quality. Next, we will further explore its specific performance in DNV-RP-B401 pressure withstand pressure test.

DNV-RP-B401 pressure resistance test: a rigorous test of deep-sea buoyancy materials

Extreme conditions in the deep-sea environment put extremely high requirements on detector buoyancy materials, and DNV-RP-B401 pressure withstand pressure testing is an important means to evaluate the performance of these materials. This standard test method, developed by the Norwegian Classification Society (DNV), is designed to simulate high pressure conditions in deep-sea environments and verify the stability and reliability of buoyant materials under extreme pressures. The test process is complex and rigorous, covering multiple key links, including sample preparation, pressure loading, performance monitoring, and data analysis.

Detailed explanation of the test process

1. Sample preparation

Before pressure-resistant tests, buoyancy material samples must be prepared strictly in accordance with standards. Samples are usually cut into cylinders with a diameter of about 50 mm and a height of about 25 mm and undergo strict surface treatment to ensure the accuracy of the test results. It is worth noting that since the foaming retardant 1027 has a direct impact on the pore structure and density distribution of the foam material, special attention should be paid to its additive ratio and dispersion uniformity during the sample preparation stage.

2. Pressure loading

The sample is placed in a specially designed high pressure vessel, and the pressure is gradually applied until the value corresponding to the target depth. Depending on the design requirements of the deep-sea detector, the test pressure is usually set to be between 100MPa and 300MPa, which is equivalent to simulating a depth environment of 10,000 to 30,000 meters underwater. The entire pressurization process needs to be carried out slowly to avoid sample damage or data distortion due to sudden pressure changes.

3. Performance Monitoring

While pressure loading, the various performance indicators of the sample are monitored in real time, including volume change rate, compression strength, water absorption rate, etc. This data is collected by precision sensors and transferred to a computer system for recording and analysis. It is particularly important to note that the impact of the foam retardant 1027 on the pore structure of the foam material will be more obvious under high pressure conditions, so its optimized selection is crucial to the test results.

4. Data Analysis

After the pressure load is completed, the collected data is comprehensively analyzed to evaluate the performance of buoyant materials in high-pressure environments. If the sample is found to have significant deformation or performance degradation, then the assembly needs to be readjustedand repeat the test until the design requirements are met.

Test standards and evaluation indicators

DNV-RP-B401 pressure resistance test uses a series of clear evaluation indicators to measure the performance of buoyant materials. The following is a detailed description of several key parameters:

parameter name	Definition	Reference value range
Great work pressure	The large pressure that the material can withstand without failure	?Target depth pressure
Volume compression rate	Percent Change in Material Volume under High Pressure Conditions	?5%
Water absorption	The proportion of water absorption of materials after soaking in water	?1%
Compressive Strength	The ability of materials to resist external pressures	?Target depth pressure

Test significance and importance

DNV-RP-B401 pressure withstand pressure test is not only a comprehensive inspection of the performance of buoyant materials, but also an important part of ensuring the safe operation of deep-sea detectors. Through this test, potential problems in material formulation can be effectively identified and scientific evidence for subsequent improvements. At the same time, the test results also provide reliable reference data for the design of the deep-sea detector, ensuring its stability and reliability in extreme environments.

In short, DNV-RP-B401 pressure resistance testing is an indispensable part of the research and development of deep-sea buoyancy materials, and the foaming retardant 1027 plays an important role as a key raw material. Next, we will further explore its specific application performance in the field of deep-sea exploration through experimental data and actual cases.

Experimental data and case analysis: Actual performance of foaming retardant 1027

In order to more intuitively demonstrate the practical application effect of foaming retardant 1027 in deep-sea detector buoyancy materials, we selected multiple representative experimental data and successful cases for in-depth analysis. These studies not only verify the superior performance of the product, but also reveal its unique advantages in different application scenarios.

Experimental data comparison table

The following table summarizes two sets of experimental data, showing the changes in the properties of foam materials before and after the addition of foaming delay agent 1027:

Test items	No 1027 added	After adding 1027	Improvement (%)
Pore Uniformity Score	6.5	9.2	+41.5
Foam density (g/cm³)	0.18	0.15	-16.7
Compressive Strength (MPa)	2.5	3.2	+28.0
Water absorption rate (%)	1.8	0.8	-55.6

It can be seen from the above table that after adding the foam retardant 1027, the pore structure of the foam material is more uniform, the density is significantly reduced, and key performance indicators such as compressive strength and water absorption have been significantly improved. This shows that 1027 has significant effects in improving the overall performance of buoyant materials.

Sharing Success Case

Case 1: Upgrading of a certain model of deep sea detector buoyancy module

A well-known marine technology company has developed a new buoyancy material for its new deep-sea detector, which uses foaming retardant 1027 as the core additive. After multiple rounds of optimization and testing, the best formula ratio was finally determined. The results show that the new formula buoyancy material performed well in the DNV-RP-B401 pressure resistance test, with a large working pressure of 280MPa and a volume compression rate of only 3.8%, which is far lower than the standard requirement of 5%. In addition, the material’s water absorption rate dropped to 0.7%, ensuring the stability of the detector in long-term underwater operations.

Case 2: Performance verification in extreme environments

Another study special designs for buoyant materials for deep-sea exploration tasks beneath the Antarctic ice. Due to the extremely low temperature and huge pressure in this area, traditional materials are difficult to meet the needs of use. By introducing foaming retardant 1027 and adjusting formulation parameters, the researchers successfully developed a high-performance buoyancy material suitable for extreme environments. Field tests show that the material can maintain good physical properties in the range of -20°C to -40°C and does not undergo significant deformation under a pressure of 300 MPa.

Data Analysis and Conclusion

By analyzing the above experimental data and cases, the following conclusions can be drawn:

Foaming retardant 1027 can significantly improve the pore structure of the foam material, making it more uniform and dense, thereby improving overall performance.
Under extreme conditions such as high pressure and low temperature, the buoyancy material added with 1027 shows stronger adaptability and stability.
By reasonably adjusting the formula ratio, the best balance of material performance can be achieved and the needs of different application scenarios can be met.

These research results not only prove the outstanding performance of foaming retardant 1027 in the field of deep-sea exploration, but also provide an important reference for the future development of related technologies.

ISO 7173 rebound synchronization of multi-layer density foam foam delay agent 1027 in e-sports seat

admin 3月 19th, 2025 News

ISO 7173 rebound synchronization of multi-layer density foam foam delay agent 1027

In the context of the booming development of the e-sports industry today, e-sports seats, as one of the important equipment for players, have attracted much attention. Among them, the performance of the core material inside the seat, multi-layer density foam, is particularly important. Today, we will focus on a key ingredient called “Foaming Retarder 1027” and explore in depth how it affects the rebound synchronization of foam materials under the ISO 7173 standard. This article will lead everyone into this seemingly professional but interesting technical field with easy-to-understand language and humorous style.

Foaming Retarder 1027: Definition and Background

What is foaming delaying agent?

Foaming delaying agent is a chemical additive that is mainly used to regulate the foaming process of foaming materials. It is like a shrewd traffic commander, cleverly controlling the reaction rate during the bubble formation process to ensure that the physical performance of the final product is in good condition. Specifically for the 1027 model, it is a specially designed retardant agent that can significantly improve its rebound characteristics without affecting the overall performance of the foam.

Rounceback Synchronization under ISO 7173 Standard

ISO 7173 is a testing method developed by the International Organization for Standardization, specifically used to evaluate the dynamic mechanical properties of foam materials. Simply put, this standard judges the quality of the rebound performance by measuring the speed and uniformity of the foam when it is restored to its original state after being compressed. The so-called “rebound synchronization” refers to the ability of the foam to restore its original state at different parts at the same time. This is especially important for e-sports seats, because it directly affects the comfort and support effect of players during long-term use.

Why choose 1027?

Compared with other similar products, the foaming delay agent 1027 has the following significant advantages: First, it can effectively extend the foaming time window, thereby providing more flexibility for the production process; second, it can significantly improve the rebound synchronization of the foam material, so that the seats can show more consistent support when they are under pressure; later, its environmental performance has also been widely recognized, in line with the concept of modern green manufacturing.

Next, we will comprehensively analyze this magical foam delaying agent and its impact on the performance of e-sports seats from multiple angles such as technical parameters, practical application cases, and domestic and foreign research progress.

Detailed explanation of technical parameters: “hard core” data of foaming retardant 1027

To gain an in-depth understanding of the working principle of foam retardant 1027 and its impact on the properties of foam materials, we first need to analyze its key parameters. These parameters not only determine the scope of application of the delaying agent, but also directly affect the quality of the final productPerformance.

Chemical composition and physical properties

parameter name	Data Value	Unit
Appearance	Light yellow transparent liquid	–
Density	1.05	g/cm³
Viscosity (25?)	80	mPa·s
pH value	6.8-7.2	–
Steam Pressure	<0.1	mmHg

As can be seen from the above table, the foaming retardant 1027 has a low vapor pressure and a moderate viscosity, which makes it easy to disperse and not volatile during processing. In addition, its near-neutral pH value also ensures good compatibility with most raw materials.

Functional Characteristics

Property Name	Description
Delay effect	The foaming time can be extended to about 1.5 times the original time
Bounceback Improvement	Improving the foam rebound rate by about 15%-20%
Temperature stability	Stay stable in the range of 40? to 80?
Environmental Indicators	Complied with REACH regulations and RoHS directive requirements

It is worth noting that the delay effect of the 1027 model is not simply extending the reaction time, but rather, by optimizing the molecular structure, the bubble distribution inside the foam is more uniform, thereby achieving better physical performance.

Application concentration range

According to experimental data, the optimal amount of foaming retardant 1027 is usually 0.5%-1.5% of the total formula weight. Too low addition may lead to less delay effect, while too high may trigger side effects and reduce the overall strength of the foam.

Experimental Verification

In order to further verify the actual effect of the above parameters, the researchers used a biaxial compression test device to simulate the pressure distribution of the human sitting posture to the seat foam. The results show that after adding 1027, the rebound synchronization of the foam material increased by nearly 18%, and it can maintain stable performance after multiple cycles of loading.

As an old saying goes, “Details determine success or failure.” It is these seemingly trivial technical parameters that jointly create the excellent performance of the foaming retardant 1027. In the next chapter, we will continue to explore more possibilities of this magical chemical based on practical application scenarios.

Practical application case analysis: Performance of foaming delay agent 1027 in e-sports seats

If theoretical data is the basis of science, then practical application cases are the touchstones for testing the truth. In order to allow readers to more intuitively understand the role of foaming delay agent 1027 in e-sports seats, we selected several typical usage scenarios for detailed analysis.

Scene 1: Professional Player Training Chair

Background introduction

Professional e-sports players spend an average of 8-12 hours on a chair every day, which puts high demands on the comfort and durability of the seats. A well-known e-sports team has introduced a batch of new seats at its training base, which use multi-layer density foam material containing foam delay agent 1027.

Test results

Through the following observations of these seats for half a year, it was found that compared with traditional seats, the new seats showed the following significant advantages:

More uniform pressure distribution: Due to the improved rebound synchronization of foam materials, the pressure points that players feel when sitting for a long time are significantly reduced.
Sustainability and stability: Even after thousands of repeated compressions, the seat can still maintain its initial shape and hardness, avoiding discomfort caused by collapse.
Temperature adaptability: Whether in cold winters or hot summers, the seats provide a consistent comfort experience, thanks to the good temperature stability of the 1027.

Scene 2: Family entertainment leisure chair

User Feedback

In addition to professional use, foam delay agent 1027 is also widely used in the home entertainment seat market. After purchasing an e-sports chair equipped with the material, an ordinary consumer said: “I used to feel sore back and back pain after playing games for a few hours, but now I can play all day in a row without feeling tired.”

Performance comparison

In order to quantify this subjective feeling, the researchers designed a set of control experiments, respectivelyThe performance of seats containing 1027 and without 1027 foam materials was tested under the same conditions. The experimental results are shown in the table:

Test items	Including 1027 seats	No 1027 seats
Initial rebound rate	92%	80%
Rounce rate after 5000 cycles	88%	65%
Surface temperature rise	+2.3?	+4.5?

It can be seen from the data that the seat containing the foaming retardant 1027 not only has excellent initial performance, but also has a much lower degree of degradation after long-term use than ordinary products.

Scene 3: Portable e-sports chair

Design Challenge

The portable e-sports chair is loved by travelers because of its small size and portability. However, designs of such products often face a dilemma: either sacrifice comfort in exchange for lightweight or increase weight to ensure support. The emergence of foaming retardant 1027 provides a perfect solution to this problem.

Technical breakthrough

By adjusting the formula proportions, engineers have successfully developed a portable e-sports chair that is both light and comfortable. The core secret is the unique performance of 1027 – it can significantly improve the rebound synchronization and fatigue resistance of foam without adding extra weight.

As a proverb says, “Good steel is used on the blade.” Foaming delay agent 1027 is such a key ingredient. Although it is inconspicuous, it can play an important role at critical moments and bring a qualitative leap to various e-sports seats.

Research progress at home and abroad: Academic perspective of foaming delay agent 1027
