All Seals gaskets and gasketing material are a combination EMI Shield with an environmental and pressure seal. All Seals wire oriented silicone is fabricated from individual wires in a silicone solid or silicone sponge elastomer. The wire provides the EMI Shielding and the elastomer provides the environmental and pressure seal. Each individual wire is oriented perpendicular to the flange mating surface and is crimped to ensure proper contact.
APPLICATIONS:
All Seals wire oriented silicone is recommended for use in industrial, military and commercial applications requiring EMI shielding and environmental sealing with a low to moderate closure force. All Seals wire oriented silicone with the silicone sponge elastomer is designed for applications which have severe joint unevenness, require low closure forces, have a 5 PSI maximum operating pressure and require a greater compressibility than silicone solid. All Seals wire oriented silicone with the silicone solid elastomer is designed for applications requiring moderate closure forces, high operating pressures and requiring a wider temperature range. For operating pressures up to 250 PSI, wire oriented silicone strips are available with the wire contained in 0.25” of the width of the silicone solid elastomer.
