4000 Series EMI Shielding Multishield

Gasket Material

Multishield is a composite material containing excellent EMI shielding with an efficient environmental seal. The material is manufactured with a matrix of wires embedded in silicone rubber and aligned perpendicular to the contact surfaces. Multishield is available in strips up to 5/8 in. wide, sheets up to 9 in. wide, custom gaskets and standard gaskets.

Application Notes

Adhesive Mounting
Multishield can be bonded to sheet metal using a thin film of RTV 3145 (or equivalent) or 3M 950 pressure sensitive adhesive. Pressure must be applied to the bond for the duration of the adhesive cure time to assure good contact of the wires to metal.

Die Cut Gaskets
Custom gaskets can be fabricated from solid or sponge multishield using inexpensive rule dies. See Fig. 1 for tolerancing and design guides. For standard product connector and waveguide gaskets, click here.

Picture Frame Gaskets
Picture frame gaskets can be fabricated from solid or sponge multishield strip material. Corner joints are bonded with RTV 3145. See Fig. 1 above for tolerances and design guides.

Compression Range
Recommended compression range is 5-10% for solid and 20-25% for sponge material.

Compression Stops
Fig. 2Multishield Gasket Drawing
Compression stops are recommended to control the amount of compression at assembly and to prevent excess compression at the fastener locations. Aluminum compression stops are available.
See Fig. 2 at right for design guides.

How to Order is explained at the bottom of page.
