Composite Wire Mesh & Silicone Gasket

DUOSIL was initially developed as a radiation and environmental seal for outdoor, all-weather commercial electronic VHF and UHF equipment. Proven to be an ideal shield and seal in these severe commercial environments, DUOSIL has also been used with great effectiveness in demanding military applications. DUOSIL EMI shielding gasket material is ideally suited for installation into the narrow grooves in cast enclosures. Its small cross section composite saves space and weight without sacrificing shielding or sealing effectiveness.

Customer Value Proposition:

DUOSIL is a composite material which provides an effective EMI shield and an optimum environmental seal. It is produced by employing a patented process and state-of-the-art elastomer extrusion technology. This process accomplishes the fusion of specially shaped silicone or fluorosilicone rubber to a knitted wire mesh shielding strip. During manufacture, a controlled amount of elastomer is permitted to penetrate the porous boundary face of the shielding strip. Following curing, the result is an inseparable composite combining the high reliability of both materials into a single rugged structure.


EMI Shielding Performance:emi gaskets--EMI-RFI Shielding Products--Composite Wire Mesh & Silicone Gasket 1

DUOSIL Shielding Effectiveness has been tested in accordance with Test Method TSETS-01, based upon modified MILSTD-285. Typical values are given in Table 1.(based on 127 mm x 127 mm aperature)

Duosil Design Considerations

Standard cross-sections are listed below. In addition, DUOSIL can be manufactured for custom designed cross-sections.
Custom designed crosssections become cost effective as the result of the elimination of costly conventional mesh to
elastomer bonding techniques. Contact Parker Chomerics Application Engineering for custom design assistance and/or
