Product Description
Laird EcoFoam CF600 Series is a conductive foam gasket for EMI shielding and grounding in electronic equipment. The construction combines conductive foam with conductive pressure-sensitive adhesive, enabling X-, Y-, and Z-axis conductivity for enclosure and connector interfaces. Laird typically recommends 25% to 50% compression of the original gasket height, with the target depending on gasket size. The material can be customized by die-cutting, hole-punching, or notching. CF600 provides distinct operating-temperature and thickness options for applications including servers and cabinets, telecommunications equipment, displays, computers, and mobile devices.
Key features
- Three-axis conductivity: X-, Y-, and Z-axis conductive foam supports EMI shielding and grounding.
- Controlled compression: Laird typically recommends 25%-50% compression of original height, depending on gasket size.
- Customizable format: Conductive PSA construction can be die-cut, hole-punched, or notched for application-specific geometry.

Additional Information
Laird EcoFoam CF600 Series
Laird EcoFoam CF500 and CF600 Series are conductive foam gaskets for EMI shielding and grounding in electronic enclosures. Both use conductive foam with a conductive pressure-sensitive adhesive and provide X-, Y-, and Z-axis conductivity. The series can be converted for custom geometry, with CF600 offering different color, thickness, operating-temperature, and shielding-performance options.

Design and installation considerations
EcoFoam is positioned for low-cycling EMI shielding and grounding applications and can be converted to suit enclosure geometry. Laird guidance emphasizes custom conversion, conductive PSA placement, and controlled gasket compression.
CF500 and CF600 comparison
CF500 and CF600 share the EcoFoam conductive-foam format but differ in color, available thickness, operating temperature, and reported shielding test data. Use the variant-specific values below rather than treating the series as one uniform specification.
| Variant | Operating temperature | Shielding effectiveness | Selection note |
|---|---|---|---|
| CF500 Series | -40 to 85 °C | 98 dB average @300 MHz; 108 dB average @3 GHz |
Gray conductive foam. The Laird product page lists 0.3, 0.5, 0.7, 1.0, 1.5, 2.0, 2.5, 3.0, and 4.0 mm thicknesses. Z-axis resistance is <0.2 Ω for CF520 on a 25 mm x 25 mm specimen at 50% compression. |
| CF600 Series | -10 to 70 °C | 60 dB average @1 GHz | Black conductive foam. Datasheet foam thicknesses are 0.3, 0.5, 0.7, 1.0, 1.5, 2.0, 2.5, and 3.0 mm, designated CF603 through CF630. Z-axis resistance is <0.2 Ω under 50% compression. |
Shielding-effectiveness results are reported at different frequencies and should not be read as a direct CF500-versus-CF600 performance ranking. The datasheets report average results using modified MIL-DTL-83528C. Both datasheets list a 12-month shelf life at 23 °C / 60% R.H.
Applications
Laird lists EcoFoam for electronic equipment where compressible shielding and grounding are needed around enclosure gaps, connectors, and similar interfaces. The use contexts below are directly supported for the CF500/CF600 family.
