The Secret of Olympic Running Training —— Nitrogen Supercritical Physical Foaming
On August 8, 2022, we watched the Anta Innovation and Technology Conference together —– the secret of Olympic running training? ——-Olympic running shoes. Olympic running shoes appeared at the press conference as the protagonist of the Anta Innovation and Technology Conference. As the protagonist, what innovative technologies have attracted the attention of many runners? Let’s take a look together. That is nitrogen supercritical physical foaming.

When it comes to Olympic running training, it must be inseparable from a pair of comfortable running shoes. Then what is the highlight of this pair of running shoes. There is no doubt that it is nitrogen supercritical physical foaming.

“Compared with the traditional foaming technology that uses carbon dioxide and other greenhouse gases, Nitrogen supercritical physical foaming uses nitrogen foaming, which reduces carbon dioxide emissions, is more environmentally friendly, and more sustainable. This is also in response to the national policy of “carbon neutrality.” The highlight of this year’s Olympic running shoes is mainly nitrogen supercritical physical foaming, and carbon tube suspension is added on this basis.

This Olympic running shoe is said to be specially made for the 5-10 km running training of the Chinese national team. The purpose is to prevent athletes from sports injuries during the training process and provide strong cushioning. Therefore, this pair of shoes, which focus on stability, protection, and cushioning, can not only be used for training by the Chinese national team, but also provide the same effect for mass runners.

Nitrogen supercritical physical foaming is a midsole technology: through the physical foaming process of injecting nitrogen into the supercritical foaming process of the midsole material. Full palm nitrogen technology effectively improves rebound, cushioning, durability and comfort.

With the blessing of nitrogen supercritical physical foaming in the midsole, the cushioning performance of the midsole is 26% higher than that of the previous midsole, ensuring the flick and sustainable durability of the midsole experience. The thickness of the midsole is also considerable this time, and the heel has an extended design, which brings a cooler foot feel and stronger cushioning.

The biggest highlight of the running shoes is that they are equipped with a newly developed carbon tube suspension system, which improves the stability by more than 20%. Ordinary running shoes use flat or three-dimensional carbon plates, but this shoe is equipped with hollow tubular carbon fibers, which can more effectively prevent the midfoot from excessive bending and collapse during running, and provide stronger arch support.

During the running process, because the carbon tube suspension is under the supercritical foam midsole material, the arch support is not strong, and there will be no arch acid feeling when wearing it, and it can effectively form force transmission. After putting on the foot, you can feel the foot feeling brought by the full palm nitrogen technology midsole, which is even better and more elastic than Boost.

The upper of this pair of Olympic running shoes is also very comfortable and stretchable, suitable for any foot shape. And as a pair of training running shoes that focus on cushioning, stability and protection. The widening of the forefoot and the widening of the heel are also essential. The design of the CUP-shaped midsole and the cup-shaped insole can also greatly improve the stability.

And for the heel area, there are not only external TPU but also the upper bag and heel widening of the midsole nitrogen technology, so the front and rear anti-rollover are very stable.

The midsole design with the heel gradient structure and the external TPU connected to the heel are combined with the upper and the midsole, which can increase the cushioning limit of the whole pair of shoes and stabilize the state when landing, better absorb shock, and rebound significantly when landing. Whether it is the upper, midsole, or foot feel, you can’t find any faults. It is suitable for a large number of people, and you will not suffer from arch soreness after long-term training and running. The running shoes made for the Olympics are worth trying and owning.

What are the Secrets of the Supercritical Midsole Foaming Technology？
Regarding the supercritical midsole foaming technology, the more popular terms and propaganda content can be said to be supercritical nitrogen foaming. Nitrogen foaming in the middle can bring a soft cushioning foot feeling.

Do you know what the real supercritical fluid is like? Nitrogen heating up and pressed above the critical point, nitrogen fluids began to pe*****te inside the raw materials. After insulation and pressure, the material expanded sharply after the pressure was quickly degraded.

Why is nitrogen foaming more common at present? It is because the nitrogen diffusion coefficient is similar to the air. And the product size is relatively stable and it is not easy to shrink. Now most of the plate foam and shoe material foaming are excellent in key properties such as cushioning and rebound rate. Let ’s briefly decrypt: first place the cross -linking plates, sheets, and shoe materials on the material vehicle, promote the high -pressure kettle, and turn off the high -pressure kettle door.

Inject supercritical nitrogen into the kettle, heat in the kettle, pressurize, so that the supercritical fluid reaches the preset temperature and pressure. The high -pressure fluid continuously spreads to the polymer matrix until the dissolving balance is achieved. And then the corresponding time is performed according to the process conditions. Inspection of insulation, and finally the need for foaming products quickly to get the need to get pressure.

Tai’an Strength Equipments Co., Ltd. invested enough manpower and material resources, developed and manufactured supercritical foam equipment with stable technical performance, and established a supercritical foam laboratory. Welcome to the supercritical midsole foaming technology in the bottom of the manufacturer to discuss it together!

Supercritical Physical Foaming Material Production Process

There are many supercritical physical foaming material, such as eva, tpu, tpee, pe, pebax, etc. These raw materials cannot be foamed by a single particle, and there must be a production process to achieve supercritical foaming conditions

What is the production process of supercritical physical foaming material? Now let’s learn this together.

Step 1: Mix the ingredients

Mix, extrude, and pelletize raw materials such as tpu, eva, tpee, pe, pebax and other required additives (excluding foaming agent) using mixer + extruder + pelletizing equipment.

Step 2: raw material impregnation

Fill the mixture particles into an autoclave, impregnate supercritical carbon dioxide or nitrogen, or a mixture of the two, and then release the pressure to foam to obtain a foamable material.

Step 3: extrusion injection molding, heating molding

Injection molding, the structure is similar to that of an extruder. The raw material is heated and softened. Using the injection machine, it is injected into the midsole mold through the channel, just like the extrusion of a syringe, and then heated and formed.

Step 4: supercritical foam material cold billet

Step 5: One-time high-pressure foam molding

Put the supercritical foam material cold billet in the material frame, send it into the autoclave, inject supercritical fluid (nitrogen or carbon dioxide or mixed gas), raise the temperature and pressure, and keep the temperature and pressure for a certain period of time according to the process conditions , and then quickly exhaust and release the pressure, the supercritical physical foaming material will be foamed.

The above is based on years of communication with customers, summed up the experience. For deficiencies, experts in the supercritical physical foaming material industry are invited to correct and guide.

Supercritical Carbon Dioxide Foaming Principle

With the development of science and technology, supercritical carbon dioxide foaming molding technology has been widely used in various fields, and this process has gradually become a “dark horse” among technological forces and is constantly being pushed to the market.

The principle of supercritical carbon dioxide foaming, the foaming process can be roughly divided into 4 stages:

(1) Make the supercritical fluid enter the polymer matrix to reach a saturated state to form a polymer/gas homogeneous system;

(2) A sudden rise in temperature or a sudden drop in pressure causes the gas in the homogeneous system to reach a supersaturated state, that is a thermodynamically unstable state, thereby causing bubble nucleation;

(3) The gas quickly diffuses into the bubble nucleus. And the bubble cells grow gradually;

(4) Rapid cooling to complete the shaping of the cell structure.

Supercritical carbon dioxide foaming is actually supercritical fluid microcellular foaming. The temperature and pressure are above the critical point, also known as supercritical fluid (Supercritical Fluid, referred to as SCF). Furthermore, the properties of supercritical foaming fluid are unique. And properties such as density, diffusion coefficient, and solvation ability are very sensitive to changes in temperature and pressure. Its viscosity and diffusion coefficient are closer to gas, while its density and solvation ability are closer to liquid.

The basic principle of microcellular foaming of supercritical fluid is to use the dependence of the solubility of gas in polymer on pressure and temperature. As a result, the polymer mixed system after supersaturated supercritical fluid enters a thermodynamically unstable state during the cooling process. So that the gas nuclei are formed. And then the microporous structure is obtained. Supercritical carbon dioxide foaming technology is a relatively effective method for preparing microporous polymer materials that has been developed rapidly in the past 20 years. The microporous structure here is similar to the popcorn structure. In recent years, it has been widely used in various fields.

Supercritical foaming materials are widely used in shoe materials, vehicles, sports equipment, ships, aerospace, furniture, etc. , decorations, toys, protective equipment and packaging industries.

It is believed that supercritical carbon dioxide foaming will be applied to more fields in the future!

Let us Appreciate the Development of Supercritical Nitrogen Physical Foaming Equipment
Foaming equipment first appeared in foreign countries, and its original model used the impeller to rotate at high speed to make foam. So it was also called “foaming equipment”. Later, with the continuous advancement of technology, its technical content continued to increase. And new models continued to emerge, forming different technical systems. We mainly produce Supercritical Nitrogen Physical Foaming Equipment.

My country began to use foaming equipment as early as the 1950s, but it was not a special foaming machine, but a mortar mixer. The foaming agent is directly added to the mortar mixer or concrete mixer. Moreover, the foaming agent is mixed with the mortar or concrete to form foam.

Around the 1970s, special equipment began to appear, that is, a high-speed impeller foaming machine. Later, the technology was continuously upgraded and replaced. Then now it has developed into the third-generation model with high-pressure inflation as the main body, which can basically meet the needs of foam concrete.

As a professional R&D and manufacturer of high-pressure supercritical nitrogen physical foaming equipment, Taian strength Equipments has developed a new generation of equipment using supercritical foaming technology through continuous upgrading and improvement.
