EMI ESSENTIALSEMI ESSENTIALS
METAL IMPREGNATED MATERIALS
ELECTROMET™ ORIENTED WIRE
ElectroMet oriented wire gaskets are EMI shielding and sealing
composites. Monel
®
or aluminum wires embedded in the
elastomer and oriented perpendicular to the mating surfaces
provide the EMI sealing. Solid or sponge silicone provides the
weather sealing; however, solid silicone weather seals are
recommended for high-pressure applications.
Silicone based oriented wire composites are capable of
withstanding temperature ranges from –70°F to 500°F
(–56°C to 260°C). Oriented wire materials are available in sheet
or strip form with a minimum thickness of 0.032 in. (0,8 mm).
Material specications and information for standard sheets and
strips are provided in Tables 1 through 3.

HOW TO SPECIFY
1. For PSA, change the fth digit to 9 for items with tape.
Example: 8408-0200-59 becomes 8408-9200-59.
2. Replace XX with material code from Table 1.
Example: To request a 3.0 in. (76,2 mm) wide x 0.032 in.
(0,8 mm) thick strip with aluminum wire in solid silicone
sponge, use 8408-0200-59.
