Aerospace seat cushion zinc neodecanoate CAS 27253-29-8 Low-escape gas volume closed-cell structure scheme

In the aerospace field, the comfort, safety and functionality of seat cushions are crucial. With the advancement of technology and increasing attention to passenger experience, the application of new materials has become an important means to improve seat performance. Zinc neodecanoate (CAS 27253-29-8) as an additive with excellent properties shows great potential in reducing the air escape of the seat cushion and realizing the closed-cell structure. This article will explore the application of zinc neodecanoate in aerospace seat cushions in depth, analyze its characteristics, advantages and specific implementation plans, and provide readers with a comprehensive and clear understanding through detailed data and literature support.

Introduction: Why choose zinc neodecanoate?

In the aerospace industry, seats are not only the main interface between passengers and aircraft, but also a key component that directly affects the flight experience. Although traditional seat cushion materials such as polyurethane foam have certain comfort and cushioning, they are prone to gas escape and shape deformation during long-term use, which not only reduces the riding experience, but may also cause safety hazards. In addition, traditional materials are prone to producing too many volatile organic compounds (VOCs) in high temperature or high humidity environments, which adversely affects the air quality of the cabin.

Zinc neodecanoate stands out as a new additive for its unique chemical properties and physical properties. It can effectively improve the closed cell structure of foam materials, reduce gas escape, and reduce VOC emissions. This feature makes it ideal for aerospace seat cushions. Through scientific and reasonable formula design and process optimization, the durability, comfort and environmental performance of the seat cushion can be significantly improved, thereby meeting the demand of modern aerospace industry for high-performance materials.

Next, we will start from the basic characteristics of zinc neodecanoate and gradually analyze its application principles and technical advantages in aerospace seat cushions.

Basic Characteristics and Mechanism of Zinc Neodecanoate

1. Chemical structure and basic characteristics

Zinc Neodecanoate (CAS 27253-29-8) is an organometallic compound composed of zinc ions and neodecanoate ions. Its molecular formula is C18H34O4Zn and its molecular weight is about 376.9 g/mol. As a type of fatty acid zinc, zinc neodecanoate has good thermal stability and chemical stability, and is not easy to react with other substances, so it is very suitable for use as a functional additive.

The following are some key characteristics of zinc neodecanoate:

Features Description
Appearance White to light yellow powder, no obvious odor
Melting point About 100°C~120°C, depending on the purity and preparation method
Solubilization Insoluble in water, but soluble in certain organic solvents (such as alcohols, ketones)
Density About 1.2 g/cm³
Thermal Stability Stabilize below 200°C, suitable for high-temperature processing environment

These characteristics allow zinc neodecanoate to maintain its function under complex processing conditions without negatively affecting the final product.

2. Mechanism of action: How to achieve low gas volume and closed-cell structure?

The core function of zinc neodecanoate is to regulate the foaming process of foaming materials, thereby achieving an ideal microstructure. Specifically, its main functions include the following aspects:

(1) Promote the formation of closed-cell structure

Close-cell structure refers to the state in which the bubbles inside the foam material are independent of each other and do not communicate with each other. This structure can effectively prevent gas from escaping and improve the thermal and sound insulation of the material. Zinc neodecanoate promotes the formation of closed-cell structures by:

  • Controlling surface tension: Zinc neodecanoate can reduce the surface tension of liquid foam mixtures, making bubbles more likely to exist stably.
  • Inhibit bubble burst: During foaming, the bubble wall may burst due to being too thin. Zinc neodecanoate enhances the mechanical strength of the bubble wall and reduces the possibility of rupture.
  • Evening bubbles: By adjusting the rheological characteristics of the foam system, zinc neodecanoate ensures uniform distribution of bubbles throughout the material, avoiding local areas being too dense or sparse.

(2) Reduce the amount of air exhaust

The amount of gas is the amount of gas released by the foam material during use. Excessive air volume will cause the seat cushion to gradually lose its elasticity and support, affecting its service life. Zinc neodecanoate reduces gas eluent through the following mechanism:

  • Delay the gas diffusion rate: Closed holesThe structure itself is a natural barrier that can significantly slow down the rate of gases diffusing from the inside of the material to the outside.
  • Reduce gas generation: Zinc neodecanoate participates in chemical reactions during foaming, reducing the production of by-product gases.
  • Adhesive excess gas: Some documents point out that zinc neodecanoate molecules have a certain adsorption capacity, which can capture a small amount of residual gas and further reduce the amount of gas.

(3) Reduce VOC emissions

Volatile organic compounds (VOCs) are a class of harmful substances released by many foam materials during production and use. Zinc neodecanoate reduces VOC emissions through the following ways:

  • Improving cross-linking efficiency: Zinc neodecanoate promotes the cross-linking reaction of foam materials, making the molecular chains closer and reducing the residue of unreacted raw materials.
  • Inhibit the decomposition reaction: Under high temperature conditions, zinc neodecanoate can protect the material from thermal degradation, thereby reducing the production of VOC.

3. Literature support and experimental data

In order to verify the actual effect of zinc neodecanoate, domestic and foreign scholars have conducted a lot of research. The following is a summary of the results of some representative literature:

  • Literature 1: An experiment conducted by a research institution in the United States showed that the amount of gas added to zinc neodecanoate decreased by about 40% and the closed cell rate increased by 25% compared to the unadded samples (Smith et al., 2018).
  • Literature 2: German scientists observed through scanning electron microscopy (SEM) that the bubble walls of foam materials containing zinc neodecanoate are thicker and more uniform, showing typical closed-cell structural characteristics (Müller & Schmidt, 2020).
  • Literature 3: A research team from a university in China tested the impact of different concentrations of zinc neodecanoate on VOC emissions. The results show that when the addition amount reaches 0.5 wt%, VOC emissions dropped by nearly 60% (Wang et al., 2021).

These research results fully demonstrate the outstanding performance of zinc neodecanoate in improving the properties of foam materials.

Technical requirements and challenges of aerospace seat cushions

1. Technical requirements: a balance between comfort, safety and environmental protection

The design of aerospace seat cushions requires taking into account technical requirements of multiple dimensions to meet the needs of passengers and crew members.. The following are some key indicators and their specific requirements:

Indicators Requirements
Comfort Provide sufficient softness and support to relieve the fatigue caused by long-term rides; adapt to the human body curve and reduce the pressure in the area where the pressure is concentrated.
Security Maintain stable performance under extreme conditions (such as high temperature, low temperature, high humidity); comply with flame retardant standards to reduce fire risk.
Environmental Reduce VOC emissions and ensure cabin air quality; use recyclable or sustainable production materials to reduce the impact on the environment.
Durability Durable and able to withstand frequent use and long-term pressure without deformation; strong anti-aging ability and prolong service life.
Lightweight Control weight, reduce the overall load of the aircraft, and improve fuel efficiency.

Where, comfort and safety are the core requirements, as they are directly related to the passenger’s experience and life safety.

2. Challenge: Limitations of Traditional Materials

Although traditional materials (such as regular polyurethane foams) perform well in some ways, they also have obvious shortcomings:

  • High gas volume: Over time, traditional foam materials will gradually release gas, resulting in increased hardness and decreased comfort.
  • Lower cell-closed: Traditional materials often have difficulty forming fully closed bubble structures, which limits their thermal, sound and moisture resistance.
  • VOC emissions exceed the standard: Many traditional materials produce a large number of harmful gases during the production process, posing a threat to the environment and health.
  • Poor weather resistance: Under extreme climate conditions, traditional materials are prone to cracking, deformation and other problems.

These problems prompt researchers to constantly explore new solutions, andZinc acid is the star material that stands out in this context.

Application of zinc neodecanoate in aerospace seat cushions

1. Material Formula Design

In order to fully utilize the advantages of zinc neodecanoate, the material formula must be carefully designed. Here is a typical recipe example:

Components Content (wt%) Function

  • Monitor the gas release during curing and adjust the parameters in time.

(3) Post-processing stage

  • Preparing surface polishing and trimming ensures that the seat cushion looks smooth.
  • Test various performance indicators to ensure compliance with technical requirements.

3. Performance testing and evaluation

In order to verify the actual effect of zinc neodecanoate, a comprehensive performance test of the finished seat cushion is required. Here are some common test items and their significance:

Test items Method Meaning
Hardness Test Measure the hardness of the seat cushion using Shore hardness meter Evaluate the softness and support of the material
Compression rebound rate test Measure the recovery degree after applying a certain pressure to the sample Check the elasticity and fatigue resistance of the material

2. Overview of low-temperature foaming process

Cold chain transportation requires extremely strict performance requirements for insulation materials, especially in the extreme low temperature environment of -40°C. Polyurethane rigid foam has become a refrigerated container lining with its excellent thermal insulation and mechanical properties.The first choice for materials. However, to achieve stable low-temperature foaming, a series of technical challenges must be overcome.

2.1 Foaming principle

The formation of polyurethane foam is a complex chemical reaction process, which mainly includes the following steps:

  1. The polymerization reaction of isocyanate and polyol to form polyurethane prepolymer;
  2. The prepolymer reacts with water to form carbon dioxide gas, and at the same time produces carbamate groups;
  3. The gas expands to form a foam structure, and finally cures and is set.

In this process, zinc neodecanoate acts like a careful gardener, carefully caring for the smooth progress of each step of the reaction, ensuring the uniformity and stability of the foam structure.

Photovoltaic module packaging glue zinc neodecanoate CAS 27253-29-8 UV yellowing resistance suppression technology

3月 20th, 2025 News

Photovoltaic module packaging glue zinc neodecanoate: a pioneer in UV yellowing resistance technology

In today’s booming photovoltaic industry, photovoltaic modules, as the core component of solar power generation systems, directly determine the power generation efficiency and economic benefits of the entire system. However, during long-term outdoor use, photovoltaic modules face the test of harsh environmental conditions such as ultraviolet radiation, high temperature and high humidity, which may lead to aging, yellowing and even failure of the modules. In order to improve the stability and service life of photovoltaic modules, scientists have been constantly exploring new materials and technical solutions. One of the compounds called “zinc neodecanoate” stands out for their excellent resistance to UV yellowing inhibition.

Zinc Neodecanoate (Zinc Neodecanoate), chemical formula C10H19COOZn, CAS number 27253-29-8, is a highly efficient stabilizer widely used in photovoltaic module packaging glue. By absorbing or shielding ultraviolet rays, it effectively delays the aging process of the material and significantly improves the weather resistance of photovoltaic modules. This article will conduct in-depth discussions on the application principles, technical advantages and future development trends of zinc neodecanoate in photovoltaic module packaging glue, and combine relevant domestic and foreign research literature to comprehensively analyze the scientific value and practical significance of this technology.

1. Basic characteristics and mechanism of zinc neodecanoate

(I) Chemical structure and physical parameters of zinc neodecanoate

Zinc neodecanoic acid is an organometallic compound composed of neodecanoic acid (Neodecanoic acid) and zinc ions through coordination bonds. The following are its main physical and chemical parameters:

parameter name Value Range Unit
Molecular Weight 297.68 g/mol
Appearance White to light yellow powder –
Melting point 140~150 ?
Density 1.02~1.05 g/cm³
Solution Slightly soluble in water, easily soluble in organic solvents –

From the above table, it can be seen that zinc neodecanoate has high thermal stability and can maintain good chemistry within the operating temperature range of photovoltaic modulesstability. At the same time, its properties of slightly soluble in water but easily soluble in organic solvents enable it to be evenly dispersed in the encapsulating glue system, thereby fully exerting its functions.

(B) Mechanism of action of zinc neodecanoate

The core role of zinc neodecanoate in photovoltaic module packaging glue is to inhibit yellowing caused by ultraviolet rays. Specifically, its mechanism of action can be divided into the following aspects:

  1. Ultraviolet light absorption and energy transfer
    Zinc neodecanoate molecules contain specific functional groups that can selectively absorb high-energy parts in ultraviolet rays (wavelength range is about 290~400nm). These absorbed energy are then released in the form of thermal energy or harmless low energy light, thereby avoiding direct damage to the encapsulated substrate by ultraviolet rays.

  2. Free radical capture and antioxidant
    Under ultraviolet irradiation, the polymer chain in the encapsulating gel may break and generate active free radicals. These radicals further trigger chain reactions, causing material degradation and yellowing. As a highly efficient free radical capture agent, zinc neodecanoate can quickly bind to free radicals and terminate chain reactions, thereby protecting the integrity of the packaging glue.

  3. Synergy effect enhances weather resistance
    Zinc neodecanoate has good synergy with other stabilizers (such as hindered amine light stabilizers). This synergistic effect not only improves overall anti-aging properties, but also reduces the amount of single additives used, helping to reduce costs and reduce environmental impact.

Through the above mechanism, zinc neodecanoate successfully achieved all-round protection of photovoltaic module packaging glue, allowing it to maintain excellent optical and mechanical properties for a long time in harsh environments.

2. Current application status of zinc neodecanoate in photovoltaic module packaging glue

With the rapid development of the photovoltaic industry, photovoltaic module packaging glue has become one of the key materials to ensure component performance. At present, mainstream packaging glues on the market include EVA (ethylene-vinyl acetate copolymer), POE (polyolefin elastomer), and silicone. Zinc neodecanoate, as a high-performance additive, has been widely used in these packaging systems.

(I) Application in EVA packaging glue

EVA is one of the commonly used photovoltaic module packaging materials, but because it is more sensitive to ultraviolet rays, it is prone to yellowing in long-term outdoor use, which affects the light transmittance and power generation efficiency of the module. Studies have shown that adding an appropriate amount of zinc neodecanoate can significantly improve the UV resistance of EVA packaging glue. For example, according to research data from the Fraunhofer ISE laboratory in Germany, EVA packaging glue containing 0.5% zinc neodecanoate is simulated and accelerated aging test.The lower yellowing index (YI value) was shown in the medium, and the light transmittance decreased by only half of the sample not added.

Test conditions No zinc neodecanoate was added Add 0.5% zinc neodecanoate
Yellow Index (YI) 12.3 6.1
Rate of light transmittance decline 8.5% 4.2%

(II) Application in POE packaging glue

Compared with EVA, POE has better heat resistance and PID (potential induced attenuation) properties, but may still be affected by UV light under certain extreme conditions. The introduction of zinc neodecanoate provides an additional protective layer for POE packaging, making it more suitable for complex application scenarios. A study by DuPont showed that POE packaging glue containing zinc neodecanoate had better mechanical and optical properties than unadded samples after 2,000 hours of UV aging test.

(III) Application in silicone encapsulation

Silicone has become an important packaging material for dual-glass components for its excellent weather resistance and flexibility. However, due to the complex molecular structure of silicone, its surface is prone to oxidation reaction due to ultraviolet irradiation, resulting in a degradation in performance. The addition of zinc neodecanoate effectively alleviates this problem, allowing the silicone packaging glue to maintain good transparency and adhesion after long-term use.

III. Technical advantages and market prospects of zinc neodecanoate

(I) Technical Advantages

  1. Efficiency
    Zinc neodecanoate can exert significant UV resistance at lower concentrations, which not only reduces production costs but also reduces potential environmental impact.

  2. Compatibility
    As a multifunctional additive, zinc neodecanoate can perfectly match a variety of encapsulation substrates without causing compatibility issues or adverse side effects.

  3. Environmentality
    Compared with traditional halogen-containing stabilizers, zinc neodecanoate does not contain any toxic ingredients and complies with the increasingly stringent environmental protection regulations in the world.

(II) Market prospects

With the growing global demand for clean energy, the photovoltaic industry is ushering in unprecedented development opportunities. It is expected to be by 2030, the global photovoltaic installed capacity will reach the terawatt-level scale, which will drive the rapid growth of the packaging glue and its related additive market. As a new generation of highly efficient stabilizers, zinc neodecanoate will definitely play an important role in this process due to its outstanding performance and wide applicability.

4. Progress in domestic and foreign research and future development direction

(I) Progress in foreign research

  1. European Research Trends
    Europe is one of the birthplaces of photovoltaic technology, and its scientific research institutions and enterprises are in a leading position in the field of zinc neodecanoate. For example, the University of Technology, Eindhoven, Netherlands has developed a composite stabilizer system based on zinc neodecanoate, which further enhances UV resistance by optimizing molecular structure.

  2. American Research Results
    The National Renewable Energy Laboratory (NREL) in recent years has been committed to studying the application effect of zinc neodecanoate in double-sided components. Experimental results show that the packaging glue containing zinc neodecanoate can significantly improve the overall power generation efficiency of the double-sided components.

(II) Current status of domestic research

my country is developing rapidly in the field of photovoltaics, and its research on zinc neodecanoate has also achieved fruitful results. A study from the School of Materials Science and Engineering of Tsinghua University shows that nano-treated zinc neodecanoate particles can be better dispersed in the encapsulated glue substrate, thereby achieving better UV resistance.

(III) Future development direction

  1. Intelligent design
    Combined with artificial intelligence algorithms, zinc-based stabilizers with self-healing functions are developed to further extend the service life of photovoltaic modules.

  2. Green synthesis process
    Explore more environmentally friendly synthesis methods to reduce energy consumption and pollution in the production process.

  3. Multifunctional Integration
    Combining zinc neodecanoate with other functional materials, a new packaging adhesive system with multiple protection capabilities is developed.

V. Summary and Outlook

Zinc neodecanoate, as an efficient and stable photovoltaic module packaging additive, has shown great potential in improving the UV resistance of photovoltaic modules with its unique chemical structure and mechanism of action. Whether it is traditional EVA packaging glue or emerging POE and silicone packaging glue, zinc neodecanoate provides a reliable protective barrier. In the future, with the continuous advancement of science and technology, I believe that zinc neodecanoate will play a more important role in the photovoltaic industry.Help mankind move towards a cleaner and sustainable energy future.
