MRI “A” Fabric
Laird Technologies’ MRI “A” Fabric is an EMI/RFI shielding
product that is manufactured using a patented, proprietary
technology. The base layer is a metallized non-woven fabric
plated with highly conductive copper and nickel for corrosion
resistance. This is bonded to a thin layer of solid aluminum.
The resulting material is a lightweight architectural material with
superior shielding effectiveness and outstanding resilience.
Specifically, this product provides superior shielding
effectiveness well in excess of industry standards throughout
the MRI frequency range. The product can be applied using
several standard construction techniques depending upon the
installation requirements or specifications. Because of the
relative ease of installation with this product, construction time
and therefore, the time to get the MRI facility on-line is greatly
reduced.
