SEFAR PowerShield – fabrics for electromagnetic field shielding
The SEFAR PowerShield fabrics are hybrid woven fabrics consisting of PET and copper monofilaments.
SEFAR PowerShield fabric properties
Electrically insulated surface
Soft: can be placed close to the surface
that needs to be shielded
Light weight (< 90 g/m²)
Thin (0.1 mm)
High air permeability (> 8000 l/m²/s)
SEFAR PowerShield benefits
Large shielding areas (> 1 m width, unlimited length)
Electromagnetic field attenuations up to 40 dB
Can be laminated into customer's product
At a typical WLAN frequency of 2.4 GHz, over 30 dB can be reached, which means that over 99.9% of the signal is blocked.
PowerShield PS01 – fabric for shielding of electromagnetic field with arbitrary (i.e. circular) polarization direction.
PowerShield PS03 – fabric for shielding of electromagnetic field with directed linear polarization.
