Medical Wire Mesh/Elastomer Combinations


Our wire mesh/elastomer combinations composite materials are produced by vulcanizing shielding mesh, normally SnCuFe (tin-plated, copper-clad, steel wire) or Monel, with an elastomer, either silicone or Neoprene. This creates a reliable low-cost shielding gasket, with environmental sealing properties.

Used in sheet and strip form, the silicone elastomer acts as an environmental seal, while the wires provide excellent conductivity to establish EMI/RFI integrity.  Available in both solid and sponge silicone, and with aluminum or monel wires. Fralock offers a wide variety of composite materials. Request the custom compositions you need.


While primarily suggested for use in gasket applications requiring high levels of attenuation along with a moisture seal, because of its economics, it is also recommended for commercial EMI shielding and RFI shielding. It is ideal for use as enclosure, window, and panel gaskets and where substantial joint unevenness is apparent. Choice of shielding mesh should take into consideration the type of metals being interfaced, to insure compatibility; and the attenuation required. The elastomer should be chosen to meet your compression, temperature, and sealing needs. The elastomer is available with an adhesive back—either temporary (PSA) or permanent (DRYBACK Neoprene only) for ease in installation.
