The composite conductive rubber strip is a new kind of polymer material, which is composed of conductive metal powder containing silver in silicone rubber or other rubber by mechanical blending, and is prepared by composite extrusion and chemical combination of non-conductive silicone rubber under specific process parameters. It has good electrical conductivity and electromagnetic shielding efficiency, excellent water vapor sealing, salt spray resistance, mold resistance, high and low temperature resistance, long service life and low manufacturing cost. According to different materials can be divided into sterling silver, aluminum plated silver, glass plated silver, copper plated silver and graphite plated nickel and so on.
