About Supercritical Foaming? First let’s know what is supercritical foaming?
We usually call it SCF shortly.Its principle is to inject supercritical fluid (such as carbon dioxide or nitrogen) into the polymer melt or solution to form uniform bubbles under high pressure. These bubbles expand as the pressure decreases, forming a foam with a microporous structure.
In plastic processing, it can be used to prepare lightweight, high-toughness and high-strength foam materials; in the textile industry, supercritical foaming can be used to prepare foam materials with microporous structure and high aerosol properties. Engineering textiles; supercritical biofoaming can also be used to prepare biomaterials with specific pore diameters and pore volumes for drug carriers and tissue engineering scaffolds.
The preparation process includes the following steps: first, inject the polymer melt or solution into the supercritical fluid and mix it thoroughly; secondly, inject the mixture into a high-pressure container and maintain the high-pressure state; finally , controlling the foaming process by controlling factors such as pressure and temperature.

Why Choose Supercritical Foaming?
1. The cell structure is more uniform and dense, and the lightweight effect is more obvious
2. Small cell size, higher density and strength, and better mechanical properties
3. More cost-effective, less materials used, and the materials can be melted and recycled
4. Healthy, environmentally friendly, pollution-free and VOCs-free
5. High production efficiency and able to achieve large-scale production
Application fields：
1. Plastic processing
Supercritical foaming is widely used in plastic processing. Through this echnology, tiny and uniform foam structures can be formed in plastics, thereby greatly improving the lightweight of plastic products and improving the toughness and impact resistance of plastic products. Widely used in shoe materials, plates and sheet products.
2. Environmental protection field
In the field of environmental protection, this technology can be used to prepare lightweight and high-strength biodegradable materials, which can be used to replace traditional plastics and other non-degradable materials. It can be quickly decomposed naturally after use, thereby reducing the pollution of the environment by garbage.
3. New energy field
In the field of new energy, supercritical foaming technology also plays an important role. For example, it can be used to prepare high-strength and lightweight battery casings, solar panel brackets, 5G communications and other components. These components are crucial to the operation and use of new energy equipment, and supercritical foaming technology can provide an efficient and environmentally friendly preparation method.
