2 / 4 page Extended Service Heights The GS8000 Series of GORE® EMI Shielding Materials performs well in both grounding and EMI shielding applications. Gore recommends using each variant within a range of service heights (gap distances). For shielding applications, Gore recommends a smaller service height range than for grounding applications to ensure a robust EMI seal. The low closure force and broad range of tolerance take-up results in multiple product choices for some gap distances. Selecting the most suitable variant for a given application depends on: 1. Gap distance of the housing that needs to be filled 2. Compression force required to achieve the specified gap distance 3. Required DC resistance for grounding applications (or required shielding effectiveness for shielding applications) at a specified gap distance Figure 1 and Figure 2 show recommended service heights (gap distances) for each variant. Figure 1: Recommended Service Heights for Use in EMI Gasket Applications 1 To measure the recovered thickness, samples were compressed to the compression stop. While compressed, the samples were subjected to a 70°C temperature soak for 70 hrs per ASTM D395B. Lastly, the samples were released from compression and allowed to recover for 30 minutes before the recovered thickness was measured. Pressure and DC Resistance Three of the variants among the GS8000 Series provide conductivity when compressed to 0.6 mm (0.24 in); however, the amount of pressure and DC resistance varies for each. Table 2 shows the values for each of these three variants.
