Electrically Conductive Silicone Sheet

Electrically conductive silicone sheet for fabricating prototype gaskets, seals and interface pads where a flexible electrical path is required. The solid black compound is carbon filled, combining silicone resilience with conductive properties for electrostatic-discharge control and EMI/RFI shielding evaluations.

Technical specification

Typical applications

• Prototype conductive gaskets and enclosure seals
• EMI and RFI shielding trials
• ESD-control interface development
• Small electronic housings and equipment panels
• Material evaluation before specifying production parts

Selecting a thickness

Choose the sheet thickness to suit the available joint space, flange flatness and intended compression. Thinner grades are useful where space is restricted or a low-profile interface is needed; thicker grades provide more material for accommodating wider gaps and surface variation. Confirm that the assembled joint maintains continuous contact without over-compressing the silicone.

Cutting and installation

1. Measure the interface and identify fixing holes, apertures and the required contact path.
2. Cut with a sharp knife, die or suitable gasket-cutting tool on a protected, stable surface.
3. Keep mating surfaces clean and free from insulating coatings, oil and debris.
4. Install with even pressure across the joint, avoiding local stretching, buckling or excessive compression.
5. Test electrical continuity and system performance on the completed assembly before production use.

Performance and design limitations

The supplier specifies a 5 Ω·cm electrical value, Shore A 65 ± 5 hardness, flame-retardant behaviour and low compression set. These are material-level properties, not a guarantee of finished-system performance. Actual ESD protection and EMI/RFI shielding depend on gasket geometry, contact area, compression, surface condition, enclosure design, grounding and operating environment.

No specific shielding-effectiveness figure, flame-test classification, environmental ingress rating or regulatory approval is claimed for the finished installation. Validate electrical, mechanical, thermal and environmental suitability in the intended assembly, particularly for safety-critical, aerospace, defence or medical applications.

Supplied: one 200 × 200 mm sheet in the selected thickness. Finished gaskets, enclosures, fixings and cutting tools shown in illustrative imagery are not included.
