[0002] Conductive foam refers to a flame-retardant sponge wrapped with conductive cloth. After a series of treatments, it has good surface conductivity and can be easily fixed on the device to be shielded with adhesive tape. There are different cross-sectional shapes, installation methods, L grades and shielding materials with shielding effectiveness for selection. Its material is very light, and its electromagnetic shielding performance dominates the electrostatic protection performance of the product and has permanence. Because the material is light, its surface impedance ability is reduced, and it has no dependence on environmental humidity and other characteristics. The conductive cloth foam has good corrosion resistance and oxidation resistance, fully meeting the needs of high-tech enterprises such as optoelectronics, microelectronics, aviation, aerospace, communication, military, chemical engineering, etc. for new antistatic materials.
