The GS5200 Series die-cut into gaskets, ideal for telecommunications and wireless infrastructure equipment.
In telecommunications applications, EMI gaskets are exposed to a variety of environmental factors, including extreme temperatures and precipitation. Despite this exposure, EMI gaskets need to provide reliable shielding and conductive performance over time to ensure electrical integrity.
The GS5200 Series of GORE EMI Shielding Solutions is a highly conductive, adhesive-backed EMI gasket material ideally suited for wireless infrastructure and telecommunications applications. Flame-retardant and engineered to withstand temperatures from -55°C to 125°C, the gaskets ensure electrical integrity in harsh environmental conditions.
The gaskets’ PTFE construction provides durability, thermal stability and superior shielding effectiveness.
Durable and thermally stable, the GS5200 Series is typically used in:
- wireless infrastructure equipment
- telecommunications equipment
- specialized portable electronic devices
Features & Benefits
The GS5200 Series materials consist of a nick-filled PTFE matrix, a conductive pressure-sensitive adhesive and a PET carrier film. The materials can be supplied in die-cut part forms — or in slit-width rolls, which is ideal for manual “peel and stick” EMI gasket applications. Because of this three-layer construction and the use of PTFE, our gaskets offer:
- excellent shielding effectiveness
- excellent reliability through Accelerated Life Testing (ALT)
- flame-retardancy (UL-94 V-0)
- broad temperature range (-55°C to 125°C)
The GS5200 Series is successfully used worldwide. If you have any questions about EMI shielding materials, please contact us.
The GS5200 Series reliably offers these nominal material properties:
|Hardness||Density (gm/cc)||Operating Temperature||Fire Safety Rating (UL-94)|
|(Shore A) 60||1.95||-55°C to 125°C||V-0|
The series’ electrical properties include superior volume resistivity and shielding effectiveness:
|Volume Resistivity (25% compression, Ag electrodes)||Shielding Effectiveness(with adhesive)|
|0.04 ohm-cm (without adhesive)||> 90 dB(ARP 1705 Method)|
The GS5200 Series is available in a range of thicknesses:

Part Number Information for GORE® EMI Shielding Materials—Strip Gaskets
|Part Number||Material Configuration||Width|
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).
