Swiss-Shield® NATURELL-ULTRA™ | Shielding fabric | Width 250 cm | 1 meter

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

OEKO-TEX® STANDARD 100

If a textile article carries the OEKO-TEX® STANDARD 100 label, you can be certain that the article therefore is harmless for human health. In many cases the limit values for the STANDARD 100 go beyond national and international requirements. The criteria catalog is updated at least once a year and expanded with new scientific knowledge or statutory requirements. ZHYO070054  OEKO-TEX® Label Check

Grounding

This product with an electrically conductive surface has to be integrated into the functional-equipotential bonding (FEB). Please find suitable grounding accessories under "Grounding".

Shielding attenuation HF & LF

This product shields high frequency electromagnetic fields (HF). Unless otherwise stated, the indicated dB-values apply to 1 GHz. Measurement from 600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006.

This product with an electrically conductive surface shields low-frequency alternating electric fields (LF).

Laboratory & expert report of shielding attenuation up to 40 GHz

We have already invested in our own professional EMV laboratory years ago. We not only use it to create our laboratory screening reports but also to check each batch daily. Additionally, we have all our products checked by an independent, well-respected expert. Double checked for twice the safety. Please find the reports above at the downloads.
