Description Areas used Properties at a glance Link to data sheet
Aluminium and monel mesh gasketing embedded in silicone rubber Particularly recommended for RFI/EMI shielding of electronic enclosures.
Designed for military, industrial and commercial shielding applications, where an excellent weather seal is required.
  • Provides a conductive gasket with about 25 contact points per cm.
  • Mesh apertures are filled with a sealing compound to provide additional environmental sealing properties.
  • 56-WWS-600 contains woven aluminium and 57-EMS-300 contains expanded monel.
Oriented wire can be included in silicone solid or foam materials. Mesh can be monel or aluminium Provide excellent performance in broad-band EMI shielding, along with good environmental sealing, for military and industrial applications.
  • The sponge construction 55-MWS-025 is particularly recommended for uneven closure surface and where relatively low closure pressure is required.
  • Gaskets can be cut from all materials using shears or die cutting tools.
  • Various widths and thicknesses can be supplied to special order.
Conductive silicone sheets from 0.5 mm thickness A range of conductive particles from carbon to silver plated aluminium are available giving a range of shielding effectiveness and galvanic compatibility for conductive seal requirements.
  • These conductive sheets can be readily cut or stamped.
  • Gasket fabrication is by use of silver conductive adhesive or conductive pressure sensitive adhesive.
Conductive silicone extrusions Many standard profiles exist. O rings can also be provided.
  • Customised extrusion tooling can be manufactured readily and, if appropriate, parts can be moulded.
