Environmental problems are becoming more and more prominent as economic development, and achieving green chemistry is an urgent task nowadays.
Supercritical foam technology is a revolutionary new technology, the foaming agents used in supercritical foaming technology are usually supercritical carbon dioxide (ScCO2) and supercritical nitrogen (ScN2), both of which are used without environmental burden.
In footwear applications, Supercritical Foam Technology is revolutionizing the sneaker industry. This technology has allowed sneaker manufacturers to expand their range of materials beyond traditional TPU, TPE, and EVA. Now, they can also use materials such as PEBAX, ETPU, and other elastomers to create sneakers with superior cushioning and support, while lightweight, durable, comfortable, and environmentally friendly.
But with the use of supercritical foaming technology to produce EVA foam has revolutionized the way many industries use this material. This technology uses a combination of high pressure and temperature to create a foam that is lightweight, durable, and highly resistant to wear and tear. The process involves injecting a gas, such as carbon dioxide (ScCO2), into a liquid solution of EVA resin and other additives. The gas is then heated and pressurized until it reaches a supercritical state, which causes the gas to expand rapidly and form tiny bubbles. These bubbles are then trapped in the liquid solution, creating a foam that has superior properties compared to traditional foams. It is faster, lighter, stronger, and more durable, making it an ideal choice for a variety of applications. For example, from footwear provides cushioning and support for the feet to sanitary products, sports leisure products, floor/yoga mats, toys, packaging, medical devices, protective equipment, water non-slip products, photovoltaic panels, and more... It is also used in automotive and aerospace applications to provide insulation and soundproofing.
