Properties

NATURELL-ULTRA™ from Swiss-Shield® is a semi-transparent cotton fabric for the shielding of high-frequency electromagnetic fields (HF) and low-frequency electric fields (LF). NATURELL-ULTRA™ is the second fabric of a new product series from Swiss Shield®. In the new ULTRA-series the silver-/copper-filament is coated with carbon, why these fabrics are electrically conductive to shield low-frequency electric fields (LF).

• Semi-transparent cotton fabric
• High screening attenuation for a cotton fabric
• Can be grounded due to the conductive surface
• Excellent cost/performance ratio
• Textile characteristics: Washable, easy to iron and process
• Quality grade: Very high

Attenuation | Grounding

• This product shields high frequency electromagnetic fields (HF). The indicated dB-values apply to 1 GHz, view chart for other frequencies. Expert reports ranging from 40/600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006, view report above.
• This product with an electrically conductive surface shields low-frequency alternating electric fields (LF). For this purpose a grounding is necessary, i.e. an integration into the functional-equipotential bonding (FEB), please find suitable grounding accessories under "Grounding".
