Product Description
Fabric- or foil-over-foam gaskets（FOF gaskets） are versatile EMI shielding solutions consisting of a conductive fabric or metal foil wrapped around a soft, resilient foam core. These gaskets provide excellent electromagnetic interference (EMI) shielding performance while maintaining environmental sealing, compressibility, and mechanical durability. They are commonly used for grounding, shielding, and sealing in enclosures and seams of electronic devices.
Typical Applications
- Telecommunications equipment
- Server cabinets and network enclosures
- Military and aerospace systems
- Consumer electronics
- Automotive electronics
- Medical devices
- Industrial control systems
- Shielded rooms or test chambers
Product Features
- Easy to Process: easily cut and shaped with scissors or cutters, allowing flexible customization.
- Excellent Abrasion Resistance: designed to withstand frequent mechanical contact and maintain long service life.
- Low Compression Force Required: effective shielding with minimal pressure, allowing the use of thinner metal sheets and reducing material costs.
- Low Surface Resistance: ensures consistent electrical conductivity and EMI shielding effectiveness.
- Cost-Effective Sealing and Shielding: an economical EMI/RFI shielding solution for enclosures, panels, and electronic assemblies.
