Sports shoes midsole material zinc neodecanoate: a revolutionary breakthrough in the million-time compression deformation recovery system
In the world of sports shoes, the performance of midsole material determines whether the shoes can provide sufficient protection and comfort to our feet. Imagine you running on the track in a pair of comfortable sneakers, every step is like stepping on a soft cloud, and behind all this, a magical material – zinc neodecanoate (Zinc Neodecanoate). This material not only has unique physicochemical properties, but also has become a star in the field of midsole materials for its excellent compression deformation recovery. Today, we will explore zinc neodecanoate and its application in sports shoes and unveil the mystery of its “million-time compression deformation recovery system”.
What is zinc neodecanoate?
Zinc neodecanoate is an organic zinc compound with the chemical formula Zn(C10H19COO)2 and the CAS number is 27253-29-8. It is composed of neodecanoic acid (Neodecanoic Acid) combined with zinc ions and is a fatty acid zinc salt compound. This material has been widely used in the industrial field due to its excellent thermal stability and anti-aging properties. However, in recent years, with the rapid development of sports shoe technology, zinc neodecanoate has gradually become the focus of the field of midsole materials with its unique mechanical properties and compression deformation recovery ability.
To better understand the properties of zinc neodecanoate, we can compare it to an all-rounder. Just like a point guard on a basketball court, you must have both speed and flexibility and be able to score a winning goal at critical moments, zinc neodecanoate also has multiple advantages: lightweight, high rebound and durability. These characteristics allow it to maintain its original shape and performance after millions of compressions, providing athletes with lasting support and cushioning.
Next, we will analyze the characteristics and applications of zinc neodecanoate from multiple angles, including its chemical structure, physical properties, production processes and actual performance in sports shoes. Whether you are an ordinary consumer interested in sports shoe technology or a professional who wants to have an in-depth understanding of materials science, this article will provide you with a comprehensive knowledge system and rich background information.
The chemical structure and physical properties of zinc neodecanoate
Chemical structure analysis
The molecular structure of zinc neodecanoate consists of two neodecanoate ions (C10H19COO⁻) and one zinc ion (Zn²⁺). Neodecanoic acid is a branched carboxylic acid with ten carbon atoms in its molecules, and due to the presence of branched chains, its melting and boiling points are lower than those of linear carboxylic acids. This feature makes zinc neodecanoate appear as a white crystalline powder at room temperature, while giving it good thermal stability and low volatility.
From the perspective of chemical bonds, the zinc ions in zinc neodecanoate bind to carboxylate ions through coordination bonds to formA stable octahedral geometric configuration. This structure not only enhances the mechanical strength of the material, but also makes it difficult to decompose under high temperature environments. In addition, due to the strong hydrophobicity of neodecanoate ions, zinc neodecanoate shows certain waterproofness and corrosion resistance, which is particularly important in the application of midsoles of sports shoes.

| Molecular Weight | 426.8 g/mol | Includes two neodecanoate and one zinc ion |
| Density | 1.15 g/cm³ | Theoretical density at normal temperature and pressure |
| Melting point | >200°C | The actual melting point depends on the crystal form and purity |
| Solution | Insoluble in water | Easy soluble in organic solvents such as or |
Physical Performance Analysis
The physical properties of zinc neodecanoate are mainly reflected in the following aspects:
1. High elastic modulus
The elastic modulus of zinc neodecanoate is usually between 100 MPa and 200 MPa, which means it can quickly return to its original state when subjected to external forces without permanent deformation. This characteristic is crucial for sneaker midsole material, as it requires absorbing impact forces every time the foot lands and releasing energy when lifting the foot, thereby improving running efficiency.
2. Wear resistance
The wear resistance of zinc neodecanoate is due to its strong interaction force between molecules. Studies have shown that under the same conditions, the wear rate of zinc neodecanoate is only about 20% of that of traditional polyurethane foam. This advantage allows sports shoes to maintain good cushioning and appearance integrity even after long-term use.
3. Fatigue resistance
Fattachment resistance refers to the ability of a material to maintain its original performance after repeated stress. After multiple compression tests, the rebound rate of zinc neodecanoate almost did not decrease significantly. For example, in experiments that simulate running environments, zinc neodecanoate samples lost only 3% of the initial value after 1 million compression cycles, much lower than other common midsole materials.
| Performance indicators | Numerical Range | Comparative Materials |
|---|---|---|
| Elastic Modulus | 100-200 MPa | EVA Foam: 30-50 MPa |
| Abrasion resistance | Wear rate <20% | Polyurethane foam: wear rate >50% |
| Fatisure resistance | Height Loss <3% | EVA Foam: Height Loss >10% |
Progress in domestic and foreign research
The research on zinc neodecanoate can be traced back to the 1980s, when scientists focused on its application as a catalyst and stabilizer. It was not until recent years that zinc neodecanoate was introduced into the midsole material field as the demand for high-performance materials in the sports shoe industry increased.
A famous foreign sports brand once mentioned in an academic paper that they successfully developed a new composite material by nanomodifying zinc neodecanoate, and the compression deformation recovery rate of the material reached an astonishing 98%. In China, the research team from the Department of Materials Science and Engineering of Tsinghua University found that by adjusting the preparation process of zinc neodecanoate, its thermal stability can be significantly improved, thereby expanding its application range in extreme environments.
Production process and technological innovation of zinc neodecanoate
Production process overview
The production process of zinc neodecanoate mainly includes the following steps: raw material preparation, synthesis reaction, separation and purification and post-treatment. Among them, synthesis reaction is the core link of the entire process and directly affects the quality of the final product.
1. Raw material preparation
The raw materials of zinc neodecanoate mainly include neodecanoic acid and zinc oxide. Neodecanoic acid is usually produced by reaction of isonononene with carbon dioxide, while zinc oxide can be obtained by calcining zinc carbonate. To ensure product quality, all raw materials need to meet strict purity requirements.
2. Synthesis reaction
At appropriate temperature and pressure conditions, neodecanoic acid is mixed with zinc oxide and stirred evenly, and then an appropriate amount of catalyst is added to facilitate the reaction. After a period of heating and cooling, a crude product can be obtained.
3. Separation and purification
The crude product needs to be washed and filtered multiple times to remove residual impurities. After that, the purification can be further improved by recrystallization or column chromatography.Spend.
4. Post-processing
The next step is to dry and package the purified zinc neodecanoate. During the drying process, temperature and humidity must be strictly controlled to avoid affecting the physical performance of the product.

Highlights of technological innovation
In recent years, with the popularization of green chemistry concepts, the production process of zinc neodecanoate has also undergone significant changes. For example, some companies have begun to use bio-based neodecanoic acid to replace traditional petroleum-based feedstocks, thereby reducing carbon emissions. In addition, by introducing a continuous flow reactor, production efficiency is greatly improved while reducing the generation of waste liquid.
Another important technological innovation is the surface modification of zinc neodecanoate using supercritical CO₂ technology. This approach not only improves the hydrophilicity of the material, but also enhances its compatibility with other components, providing the possibility for the development of multifunctional composite materials.
