The GS2100 Series provides superior shielding effectiveness for aerospace applications.

The GS2100 Series provides superior shielding effectiveness for aerospace applications.

In challenging conditions, such as those experienced in aerospace, shielding materials are depended on to provide electrical performance regardless of the abrasion, altitude shifts and extreme temperatures they face.

Approved for spaceflight and military applications, the GS2100 Series of GORE® Shielding Solutions protects signal integrity in harsh environments. The GS2100 Series consist of a conductive, adhesive-backed, EMI gasket material that is moderately soft. The materials can be supplied in die-cut part forms — or in slit-width rolls, which are ideal for manual "peel and stick" EMI gasketing applications.

The GS2100 Series consists of a carbon-filled cellular PTFE matrix, a conductive pressure sensitive adhesive and a PET carrier film.


The GS2100 Series is approved for military aerospace and spaceflight applications, commonly used in:

military wireless communications equipment

military and space avionics

high-frequency cable connectors in military and space applications

telecommunications equipment

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. Please contact us for more information about the right solution for your design needs.
