Oriented wire shield
Oriented wire shield 5711 – 5722 is a composite gasket material consisting of a large number of small wires embedded and bonded in solid or sponge silicone, or fluorosilicone elastomer for oil resistance.
The wires provide excellent conductivity to establish EMI/RFI shielding.
The material is used in military, industrial and commercial products requiring EMI suppression, grounding, or static discharge. It is very suitable for applications where an environmental or pressure seal is required.
The sponge version is used in cases where the joint is very uneven, or if lower closure forces or greater compressibility are required.
Dimension
We produce sheets of 150 x 900mm, from which we can then cut gaskets without interruptions. Bigger gaskets can be welded/joined together in order to prevent waste of material.
Custom compositions are available on request, simply by sending a drawing with the desired dimensions to our email address info@hollandshielding.com.
Options
- Temperatures up to 220 °C
- High shielding performance
- Water sealing up to 10 meters
- Pressure resistant
- Salt spray/chemical resistant
- Fluorosilicone rubber for fuel/oil resistance
- Supplied as sheets, strips or die-cuts
Available thicknesses
0.81, 1.13, 1.38, 1.57, 2.40, 3.18, 3.96, 4.78, 6.35 mm. Other thicknesses on request.
