Graphite-over-foam EMI Gasket

Graphite over Foam Gasket

Overview

Graphite over Foam Gasket is a thermally conductive EMI shielding gasket that combines a compliant foam core with an outer synthetic graphite layer.
It delivers reliable EMI grounding and in-plane thermal dissipation while maintaining low compression force, excellent resilience, and lightweight construction—ideal for high-frequency, high-power-density electronic assemblies.

Omnidirectional Conductive

Foam

Gasket

Overview

The Omnidirectional Conductive Foam Gasket offers full three-axis (X, Y, Z) conductive contact and shielding within a compressible foam core wrapped in metallized fabric or foil. It is designed to handle complex geometries and high-density electronics, delivering superior EMI performance in enclosure seams, connector interfaces, and compact modules.

Core Features & Benefits

Dual-function performance: EMI shielding and thermal conduction in a single gasket
Low compression force: Protects delicate housings and thin enclosures
Excellent rebound & fatigue resistance: Stable performance over repeated compression cycles
High in-plane thermal conductivity: Efficient heat spreading across interfaces
Lightweight & thin-profile design: Supports compact and high-density layouts
Abrasion-resistant graphite surface: Maintains conductivity during assembly and service
High-volume manufacturability: Compatible with die-cutting and automated assembly
UL94 V-0 flame rating & environmental compliance: Meets RoHS and REACH requirements

Core Features & Benefits

Three-axis Conductivity — Provides electrical contact and grounding in all directions, ideal for fine-pitch and high-speed designs.
Low Compression Force — Engineered to establish reliable contact with minimal force and accommodate tolerant assemblies.
High Shielding Effectiveness — Achieves > 90 dB attenuation across broad frequencies in compact form factors.
Durable Construction — Metallized fabric resists abrasion, shear, and repeated closure cycles, ensuring long-term reliability.
Customizable Profiles — Available in die-cut shapes, slit strips, adhesive-backed formats and designed for odd-shaped or space-constrained applications.
Compliance — Flame-retardant, halogen-free, and RoHS-/REACH-compliant options available for rigorous regulatory environments.
