GORE® EMI Shielding Materials - GS500 Series

The GS500 Series of GORE® EMI Shielding Materials is a conductive, adhesive backed, EMI shielding material that is moderately soft and is ideally suited for wireless infrastructure and telecommunications applications. Materials can be supplied in die-cut part forms or in slit width rolls. Slit width material is ideal for manual "peel and stick" EMI gasketing applications.

The GS500 Series consists of a carbon-filled cellular PTFE matrix, a conductive pressure sensitive adhesive, and a PET carrier film.

Features and Benefits

  • Good shielding effectiveness
  • Excellent reliability through Accelerated Life Testing
  • Flame retardant (UL-94 V-0)
  • Broad temperature range °C)
    • 0 to 95 (with adhesive)
    • -200 to 200 (excluding adhesive)
  • Years of successful use worldwide

Typical Applications

  • Wireless infrastructure equipment
  • High frequency cable connectors
  • Telecommunications equipment
  • Portable electronic devices

Design Considerations

When optimizing a gasket shielding solution, consider the housing design as well as the EMI gasket performance. Important considerations in the housing design include flatness, surface roughness, material type, rigidity, contact area, tolerance take-up, conductivity, fastener type, and fastener locations.

Key factors in an EMI gasket include softness, tolerance take-up, conductivity (DC resistance), and shielding effectiveness both before and after Accelerated Life Testing (ALT). Sealing Devices Application Engineers can provide expert design assistance and rapid prototyping for all your EMI shielding needs.
