Oriented Wire
Shield and Seal
This composite gasketing
material is designed for use in suppressing
EMI/RFI while at the same time providing an
effective, full pressure, environmental
seal between mating surfaces. It is
comprised of conductive wires oriented
perpendicular to the mating surfaces and
embedded in sponge
or solid silicone elastomer . It
is recommended for use in both military and
commercial applications that require high
levels of EMI/RFI shielding over a wide range of
temperatures and environmental conditions |

Elastomer
gasketing with conductive suspended wires
provides EMI/RFI shielding with
full pressure seal
Oriented Wire Shield
and Seal is a highly conductive composite
shielding material consisting of sponge or soild
silicone elastomer in which oriented - monel or aluminum wires are
chemically vulcanized into the elastomer.
These embedded wires are strategically constructed to provide more than 900 physical
contact points per square inch with mating metallic surfaces. The silicone elastomer stabilizes each individual conductive wire even under the most severe
compressive loading. The silicone provides resilience
that assures effective sealing even where the mating
surfaces are largely uneven. It also prevents moisture, even water, from penetrating through or
around critical gasket/equipment interfaces.
Dependable
shielding in extreme
environments
Oriented Wire Shield and Seal gaskets will withstand a wide range of
temperature extremes (-65 to 200 Celsius) and the most severe environmental conditions
while providing a metal-to-metal conductive path. Among
their many features are minimal compression set
with corresponding wideband shielding
effectiveness.
Materials
and gasket forms for all
applications
Oriented Wire Shield and Seal gasketing is available in sheet, strip or ring
form. Standard conductive media is Monel or Aluminum wires. Pressure sensitive
adhesive backings are available where required for ease of installation. Fluorosilicone compounds are also available for applications involving contact
with chemical solutions or silicone oils.

NOTE: For
pressure-sensitive adhesive (PSA) backing,
substitute 7 as the second digit (1713) for solid
silicone; 8 as the second digit (1823) for sponge.
2. Select height and width from the Sheet
Identification and P/N Selection Chart shown below.
Replace the first 2 digits of the second series
with the height in decimal inches and the second 2
digits with the width, also in decimal inches. Do
not use metric dimensions to order.
Example:
To order solid silicone sheet, Monel wires, .062"
thick by 3" wide;
order 1213-0630.
Example:
