Fabric-Over-Foam Gaskets

Laird’s Fabric-over-Foam 779 EMI gaskets provide wide compression ranges, and excellent EMI shielding performance for customers where EMI issues occur. The 779 EMI gaskets are composed of electrically conductive fabric wrapped around a foam core. They are supplied with a conductive pressure sensitive adhesive (PSA). 

Features and Benefits

  • Low compression forces allow for use of lighter materials
  • Operation temp up to 85oC
  • RoHS compliant
  • Halogen-free per IEC-61249-2-21 standard
  • Low surface resistivity of < 0.05 Ω/□provides excellent conductivity
