Electromagnetic interference shield is a kind of material used to suppress electromagnetic interference, its main application includes the manufacture of electronic equipment, the design of communication system and so on. According to different needs and environments, the materials and shapes of electromagnetic interference shielding strips are also different. At present, the main products on the market are beryllium copper shielding strip, conductive silicone rubber strip, aluminum silver plated water vapor seal high conductive rubber strip, conductive foam strip, rectangular square conductive rubber strip, nickel carbon shielding waterproof silicone strip and other different kinds of products. These products have good electrical conductivity and shielding effect, which can effectively reduce the interference of electromagnetic waves and improve the working stability and communication quality of electronic equipment.
