These species include woven wire mesh, wire wound around the elastic core, the orientation of the elastic wire body.Low-cost metal-based EMI shielding products for decades been used in the civilian market, they typically provide between 20MHz and 10GHz attenuation of 60dB to 100dB. These composite materials are also well suited for frequencies above 1GHz required shielding level below 80dB-90dB, or special sealing performance of the military - space applications.
MESH STRIP standard lining is Monel (a nickel copper alloy) or Ferrex * (tin, copper-clad steel) wire woven. Other metals and alloys (such as aluminum mesh) can also be used. Monel materials, the most widely used because it has good aging properties, tensile strength and spring-like quality. Ferrex provide the best shielding performance, especially in the H-field, but the corrosion resistance is limited. Standard foam core materials include neoprene (MIL-R-6130, Type) hollow solid neoprene (MIL R-6855, grade), closed-cell silicone foam (AMS-3195) hollow tubes and solid silicone (ZZ-R-765, Level 2B). In addition to the standard set out in almost any elastomer core sections are capable of producing, including the UL94V-0 to determine the core material. This information is divided into the following categories to describe: l Full Metal mesh l with a rubber core metal mesh l hollow metal mesh l combination of environmental sealing wire l wrapping wire mesh cable shield
