RFI-EMI conductive shielding fabrics
Shielding effectiveness is determined by a combination of two events: reflection and absorption of RF signals.
Absorption depends on the bulk, or thickness, of the shield material. However, reflection occurs at the shield
surface and its effectiveness is independent of thickness. Reflection is the determining factor for all high
frequency signal attenuation. (Note: When these materials are used in another regime; i.e., conductive shielding
gaskets, conductivity is the determinant.)
Maximum reflection occurs with the highest conductivity materials. The best overall metals are copper, nickel and
combinations of both - based on high conductivity, compatibility with mating metals, manufacturing versatility and
cost. The large 41.0” material width
(1040mm)
minimizes seams; thin .003” - .004” cross sections
(0,08 - 0,10mm)
maximize conformability to irregular surfaces.
components
applications
• Bonding or laminating to complex geometric shapes (includes optional hot melt adhesive, or conductive
adhesive backing)
• Large surface coverage with minimal seams due to 41.0” material width
(1040,0mm)
• ESD, RFI-EMI; shielding attenuation >70.0 dB up to 10.0 GHz for CuNi type.
• Enclosure panels and frames, seams, joints, shield curtains for back panel openings
• RFI-EMI conductive shielding gasket cover membranes (i.e., with foam or silicone core structures)
• Architectural shielding; shielded room finishing - ceilings, walls, floors; special purpose rooms
options
equipment, architectural
• All materials are available in non-adhesive, hot melt adhesive or conductive adhesive backing
• Standard sheets are 41” x 36”
(1040,0 x 914,0mm)
• Longer lengths may be ordered by adding a suffix “X” to any part # with qualifier; i.e., X = 73”
(1854,0mm)
• Full rolls are 325’-0 long
(100M),
and can be ordered by specifying the suffix “X” with qualifier; i.e., X = 325’ roll
(100M).
Note: conductive adhesive versis are 164’
(50M)
long.
