The main differences between open-cell and closed-cell Foams are their structural and physical properties and how these differences affect their application scenarios.
Open-cell and closed-cell foams have sigNificant differences in physical properties, application areas, and production processes, and the choice of which foam material to use should be based on specific needs.

Electromagnetic pollution can seriously affect human life. First of all, in the military and communication fields, electromagnetic wave leakage can lead to information leakage. Electromagnetic interference can deal a serious blow to the command, control and communication systems of the military.

Spherical open-cell aluminum foam, with light weight, temperature resistance, corrosion resistance, sound absorption and noise reduction, is widely used in aerospace, rail transportation, automobile manufacturing and other fields, and is an important strategic material for both civil and military use.

Copper foam is a porous material made from a mixture of metallic copper and a surface foaming agent, which is baked and expanded at high temperatures. In the sintering furnace, copper foam is easy to oxidize in the air because oxygen molecules can enter inside the foam through the foam pores and react with the copper to produce copper oxide.

Ceramic foam filter can effectively intercept inclusions in liquid metal and improve casting quality and yield, ceramic foam filter has four major mechanisms to effectively purify liquid metal.

Construction of sound barriers on both sides of the highway is an effective way to prevent and control highway traffic noise pollution, sound barriers with sufficient height, length, in general, can reduce noise 10-15dB. If you want to improve the amount of noise reduction, you need to be in the structure and design of the sound barriers, to improve.

Silicon carbide ceramics are making waves in the field of advanced materials with their outstanding performance and wide range of applications.  From high-temperature environments to abrasive and corrosive environments, silicon carbide ceramics have proven to be a versatile and reliable choice in a variety of industries.

In recent news, the construction world is abuzz with the discovery of a breakthrough fire-resistant material – aluminum foam.  This innovative material has the potential to revolutionize the way we approach fire safety in buildings, providing designers and occupants with new levels of protection and peace of mind.

Silver foam is a new type of functional material with high porosity, large specific surface area, and good permeability, etc. Using it as a catalyst has the advantages of high activity, good stability, and good selectivity, which makes it an ideal replacement for the existing silver catalysts.

The installation of aluminum foam material is relatively simple and convenient:
Wall installation steps are suggested: dry hanging → main keel → vice keel → hanging plate or self-tapping nails combined with gluing → main keel → vice keel → gluing (according to the climatic conditions and wind-blocking design choice of dry hanging or gluing);
Because the aluminum foam panel is very light, ceiling installation can be designed at will gluing, I-beam hanging, magnetic suction, very simple.
