Mesh/Elastomer Combinations
SAS SEALTRON Materials include wire mesh and elastomer combinations as well. This material is ideally suited for situations where joint unevenness is a concern, due to its ease of compressibility. Typical applications for wire mesh and elastomer combinations are enclosure gaskets which require both an environmental seal and EMI shielding. Additionally, for applications which require both low closure force with high deflection where sponge elastomers are used it is recommended to add compression stops to the gasket as shown in the last diagram of this section to prevent over compression. These can be supplied bonded in the gasket as washers, as illustrated or as solid metal “plugs”.
These are available in various different metal and elastomer combinations.
An adhesive strip can also be added to the elastomer for ease of assembly.
The following part number system classifies the material as being part of our Wire Mesh / Elastomer Combinations line.

Replace the first x in the second series of the part number (e.g. 4xxx-x) with a 0 for Figure 1 configuration and a 9 for Figure 2 configuration.
Additionally, for solid elastomers, it is recommended the wire be .031” higher then the elastomer. To order with an additional .031” height on the elastomer replace the first x in the second series of the part number (e.g. 4xxx-x) with a 3 for Figure 1 configuration adding .031” to the wire or a 7 for Figure 2 configuration adding .031” to the wire.
Further, for solid elastomers where a 5 degree draft is desired on each side of the elastomer, where the represented width is the widest part where the elastomer meets the mesh, replace the first x in the second series of the part number (e.g. 4xxx-x) with a 5 for Figure 1 configuration only.
Replace 4xxx with the appropriate Material PN as illustrated in the table above this table to complete the part number. To add PSA backing to the elastomer portion of the Wire Mesh Elastomer Combination replace – NA with – A1.
The following chart shows typical performance characteristics of the wire mesh.
