GORE EMI Shielding GS2100 Series Ma Best shielding effectiveness in lightweight materials approved for military and spaceflight applications Military and aerospace applications must not only ensure reliable signal transmission but also reduce weight as much as possible. The lightweight GS2100 Series of GORE EMI Shielding Materials reduces overall product size while providing excellent shielding performance. The low outgassing materials used in the GS2100 Series result in conductive solutions approved for DEF-STAN, MIL-SPEC, NASA, and ESA applications. The GS2100 Series of GORE Shielding Materials is engineered with a conductive EMI gasketing material that is moderately soft, which provides excellent shielding effectiveness in housings with surface variations like those in magnesium as-cast enclosures. With trace widths as narrow as one millimeter, the GS2100 Series improves flexibility in complex packaging designs. Their peel-and- stick adhesive backing makes installation quick and easy, whether used in a new design or a retrofit. These gaskets can be supplied in die-cut forms or in slit-width rolls.
