Principle of supercritical fluid foaming technology

Supercritical fluid microcellular foam injection molding technology

Supercritical fluid foaming technology    
     
        Supercritical fluid, i.e. nitrogen or carbon dioxide in supercritical state, is used as foaming agent. After accurate measurement, it is fully mixed with thermoplastic melt to form a homogeneous system of melt glue / foaming agent, including single-phase solution. The obtained homogeneous system can realize the required foaming products through foaming molding die or injection mold, such as microcellular foaming Products and structural foaming products, high foaming materials.
Compared with the traditional foaming agent, it not only has the advantages of economy, safety and environmental protection, but also is suitable for processing almost all thermoplastic resins and product application fields, such as food and drug packaging. Because of the more economical and convenient preparation of microcellular foaming products, the application field of foaming materials can be further expanded.
It includes injection molding, extrusion molding and so on.
