Fabric-over-Foam (FoF) Conductive Gaskets

The Perfect Combination of Mechanical Flexibility and High EMI Shielding

Fabric-over-Foam (FoF) conductive gaskets from Laird Performance Materials are the industry-leading solution for gap shielding in electronic enclosures. The gasket consists of a soft, resilient foam core wrapped in a high-quality conductive fabric (typically Nickel/Copper), ensuring maximum electrical continuity between enclosure parts while requiring minimal closure force.

Why Choose Laird’s Fabric-over-Foam Gaskets?

FoF gaskets offer critical engineering advantages:

Low Compression Set: Thanks to the high-quality foam core, the gasket returns to its original shape even after thousands of opening and closing cycles, without deforming the enclosure’s mechanical structure.
High Shielding Effectiveness: The conductive fabric provides excellent attenuation of over 100 dB across a wide frequency range (100MHz to 10GHz and above).
Flame Retardancy: Gaskets can be ordered to meet the UL 94V-0 standard, which is critical for telecom equipment, servers, and medical systems.
Wide Profile Variety: Available in hundreds of geometric shapes (D-shape, C-shape, Square, Bell, etc.) for a perfect fit in any slot or rail.

Common Applications

Telecom Enclosures & Servers: Shielding for doors and removable panels.
Medical Equipment: Protecting sensitive components from external interference.
Electronic Packaging: Ensuring electrical continuity in connections between sheet metal parts or CNC enclosures.
Displays & Monitors: Preventing RF leakage around the screen frame.
