Supercritical foaming equipment is a new type of physical foaming equipment. In the preparation process, the supercritical fluid medium is first injected into a special device to make the medium and the molten raw material mix and diffuse fully and uniformly to form a single-phase mixed sol, and then by changing the pressure, the medium is precipitated to form a large number of bubble nuclei. In the subsequent cooling and molding process, the bubble nucleus inside the sol is continuously grown and molded by adjusting and controlling the parameters, so as to obtain foamed products with better performance.
Supercritical Foam Equipment
Description
Supercritical foam equipment is one kind of physical foaming equipment which uses supercritical fluid foaming technology to inject carbon dioxide or nitrogen as the foaming medium into the supercritical foaming equipment, so that the gas and the molten raw material are fully mixed and diffused to form a single-phase mixed sol, which produces a large amount of sol. The pressure drop caused the gas to separate out to form a large number of bubble nuclei. In the subsequent cooling and molding process, the bubble nucleus inside the sol continuously grows and forms, thereby obtaining a microcellular foamed plastic product. The supercritical foaming equipment is an important equipment to realize this process.
As a professional supercritical equipment designer and manufacturer, STRENGTH Equipment can design and manufacture supercritical foaming Equipment for mass production and laboratory applications to meet your needs. The foaming agent of supercritical fomaing machine could be N2 or CO2., its up to the foaming material requirements.
Advantages of supercritical microcellular physical foaming products
1. The physical foaming unit cell is finer and lighter;
2. Physically foamed products with better mechanical properties;
3. Higher cost performance, less materials, and degradable materials;
4. Physical foaming is healthier and environmentally friendly, no pollution, no VOC emissions；
Supercritical foamable materials
Various polymer elastomer materials such as EVA, TPU, PE, PP, ABS, nylon, etc.
Application fields of supercritical foam products
Physically foamed products are widely used in aerospace material, high-speed rail material, shoe materials, packaging, boards, sports equipment, children’s toys, environmental protection decoration, sofa bed material and other fields because of their environmentally friendly pollution-free, no chemical residues and odors, and better performance.
