Graphite over Foam 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
