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 penetrate 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!
