Conductive elastomers shield enclosures

30 May 2012 Circuit & System Protection

Electrically conductive elastomers are used for shielding electronic enclosures against electromagnetic interference (EMI). They provide environmental sealing and excellent mechanical and electromagnetic shielding properties.

Laird Technologies offers a wide variety of conductive filler materials in extruded, moulded die-cut, dispensed form-in-place, printed and coated formats.

Usually, the shielding system consists of a conductive gasket sandwiched between a metal housing and lid. The primary function of these gaskets is to provide sufficient electrical conductivity across the enclosure/gasket/lid junction to meet grounding and EMI shielding requirements, as well as to prevent fluid intrusion into the electrical components.

Laird Technologies offers ElectroSeal and ElectroMet ranges. ElectroSeal are dispersed filler particles in elastomers and ElectroMet is an oriented wire in solid and sponge elastomers, and impregnated wire mesh and expanded metals. These products are suitable for both military and commercial applications requiring both environmental sealing and EMI shielding.

Compounds can be supplied in moulded or extruded shapes, sheet stock, custom extruded or die-cut shapes to meet a wide variety of applications.

The product offering from Laird Technologies meets a wide range of customer requirements. The classifications of the most common materials are based on cost and specific applications. There are over 30 compounds available.

Conductive extrusions offer a wide choice of profiles to fit a large range of applications. Custom dies can be built to accommodate customers’ specific designs. They are available in a wide variety of conductive filler materials with shielding effectiveness up to 120 dB at 10 GHz.
