Fabric-Over-Foam Gaskets

Laird Technologies’ Fabric-over-Foam (FoF) 51G EMI gaskets provide excellent EMI shielding performance for customers where EMI issues occur. The 51G Series EMI gaskets are composed of electrically conductive fabric wrapped around a soft urethane foam core. They are supplied with either a conductive or non-conductive pressure sensitive adhesive (PSA), and can be equipped with an Extended Release Liner (ERL) on the adhesive. The 51G is a halogen-free, UL 94V0 rated product that can be created with cross-section profiles such as rectangle, D, C, P, T, knife, bell shapes, and others. The 51G EMI gaskets can be further customized to an application by die-cutting, hole punching, notching, etc.

Features and Benefits

  • Fabric-over-Foam gaskets are RoHS compliant
  • Halogen-free per IEC-61249-2-21 standard
  • UL 94V0
  • Low surface resistivity of < 0.07 Ω/□ provides excellent conductivity
  • Shielding effectiveness of >100 dB across a wide spectrum of frequencies
  • Extremely low compression forces allow for use of lighter materials
  • Fabric is highly conductive to provide good EMI shielding and grounding
  • Abrasion resistant metallized fabrics show virtually no degradation in electrical performance after 1,000,000 cycles
  • Laird Technologies’ proprietary coating prevents fabric fraying and fingerprinting
  • Available with conductive or non-conductive PSA
  • Many cross-section profiles available such as rectangle, D, C, P, T, knife, bell and more
  • Profile gaskets can be cut to specified lengths, kiss-cut on release liner, or mitered to form frame configurations
