Summary
GORE-SHIELD
®
GS2100 EMI Gasket is a conductive, adhesive
backed, EMI gasketing material that is moderately soft and is
approved for spaceflight and military applications.
GORE-SHIELD
®
GS2100 EMI Gaskets 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.
GORE-SHIELD
®
GS2100 EMI Gaskets consist of a carbon-filled
cellular PTFE matrix, a conductive pressure sensitive adhesive,
and a PET carrier film (see Figure 1).
Applications
EMI shielding for wireless infrastructure and microwave
equipment, high frequency cable connectors, and
telecommunications equipment in addition to high frequency
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).
Gore application engineers can provide expert design assistance
and rapid prototyping for your EMI shielding needs. Contact Gore
for additional information.
