SSI's engineered electrically conductive elastomers (conductive rubber) provide sealing solutions for mission critical applications that require both environmental and electromagnetic interference, electrostatic discharge, and radio frequency shielding. The incorporation of elastomers with alloys creates a multi-material compound capable of providing electrical shielding with the superior physical properties of an engineered elastomer. SSI's material engineering team utilizes a variety of elastomeric binders combined with a large array of conductive fillers to custom design solutions for all types of applications in the aerospace, semiconductor, and medical device industries.

Fabric over foam gaskets are made of a resilient foam core, bonded over with conductive fabric. More than 70 different profiles offer unlimited selection for any application. Some profiles contain rigid inserts. Metallized conductive fabric bonded to resilient core (available in urethane foam, neoprene sponge) offers a good shielding efficiency and works as a seal to block air, light and dust.
- UL94-V0 certified
- RoHS compliant

Over-Molded Cover Seals
Enclosure shielding and environmental sealing performance are improved in a number of ways when conductive elastomer gaskets are molded directly to a flange surface instead of being adhesive bonded or mechanically attached. Over-molded gaskets provide the optimum seal profile, achieving more gasket deflection with limited closure force when compared to flat, bonded gaskets.
Molded D- and O-Rings
Parker Chomerics' D-ring and O-ring conductive elastomer gaskets provide moisture/pressure sealing and EMI shielding when compressed in a properly designed groove. They are interchangeable with standard non-conductive seals of the same dimensions.
Custom Molded Gaskets
Parker Chomerics can mold conductive elastomer EMI gaskets to fit practically any application. Custom molded elastomer gaskets can include tight corners, retention bumps and other special geometries. Many other features can be added, such as fabric or mesh reinforcement, pressure-sensitive adhesive, fasteners and compression stops. Non-conductive silicone environmental seals can be bonded to or co-molded with conductive EMI shielding elastomers.
Connector Gaskets
Chomerics' die-cut conductive elastomer gaskets provide shielding and environmental sealing when inserted between a connector flange and their mating surfaces. A variety of Mil-Standard mounting flange EMI gaskets are available, along with interfacial EMI seals and jam nut seals. Chomerics also provides D-subminiature rectangular gaskets in a complement of shell sizes from 9 to 50 pin.

Conductive Non-Woven textile appears as compact felt, characterized by a less volumetric resistivity, very good punching and competitive price with respect to other materials, above all for medium/great (>5.000 pieces).
Such materials can be supply as semifinished in rolls or various height and length spools for following customer machining or punching on drawing.
Their use is recommended when it take a good Shielding Performance, electrostatic discharges protections or grounding, without particular environmental requirements.
Typical applications are: cable flanges, panel or plate connectors, permanent closings on cabinets and easy to apply for shielding rooms.

Conductive foam offers unmatched compression set performance while providing a relatively soft Compression Load Deflection (CLD) curve. Lower CLD properties further reduce the potential for distortion while in application. When the gasket is compressed greater than the recommended 50%, compression force is reduced by half.
A popular Laird Technologies product in this category is Electro-Seal conductive elastomers. Electro-Seal conductive elastomers are ideal for both military and commercial applications requiring both environmental sealing and EMI shielding. Compounds can be supplied in molded or extruded shapes, sheet stock, custom extruded or die-cut shapes to meet a wide variety of applications. Electro-Seal conductive elastomers provide shielding effectiveness up to 120dB at 10GHz.

Conductive urethanes are made by three layers, PET + PU + PET, heat sealed between them and made conductive through chemical-galvanic bath (Cu+Ni).
They appears as soft mat (width 30cm), sufficiently compact.
Able to realize punching gaskets for flanges and connectors, are also particularly suitable to realize shielding cells (compartimentation).

When your designs require EMI gaskets that exhibit high attenuation and low closure force, Metex Conductive Fabric gaskets are an ideal choice.
By combining a soft core with conductive fabrics, we have created a gasket that will provide >65 dB attenuation at 1 GHz, and compression loads under 4 lbs. per inch at 25% deflection. Low compression forces allow for lighter, less expensive enclosure designs.
Conductive Fabric gaskets are the ideal gaskets to use with conductive coatings that can be scratched or damaged by other more abrasive gasket materials. The conductive fabrics available include abrasion-resistant copper and nickel.

Fabric-over-Foam EMI gaskets offer high conductivity and shielding attenuation and are ideal for applications requiring low compression force. The Fabric-over-Foam profiles are available in a UL 94V0 flame retardant version and offer high abrasion and shear resistance. Typical Fabric-over-Foam EMI gasket applications include shielding or grounding of computer and telecommunications equipment seams and apertures.
Laird Technologies provides the widest range of shapes and thickness to meet any design need. Depending on the shape and Fabric-over-Foam materials, compression of the gasket from 30% to as high as 75% can be allowed, thereby accommodating the tolerances of your mechanical system.
There are a wide range of enclosure materials and operating environments, so material compatibility is critical for reliability. Laird Technologies offers the widest range of materials in the industry and can design a solution for your application. Custom sizes and shapes can be designed to meet your application requirements, along with special purpose pressure sensitive adhesives and other features.
