YSHIELD® SILVER-TWIN | Shielding fabric | Width 150 cm | 1 meter

Properties

SILVER-TWIN is a compact cotton/silver fabric for the protection against high-frequency (HF) radiation. Typical application as curtain, to sew clothes, handy bags, etc..

Special feature: The frontside is made of white cotton, while the backside is densely woven with a silver thread. Despite the extremely high attenuation due to the dark silver threads on the backside, this fabric has a light gray frontside!

• Maximum high screening attenuation, even at very high frequencies!
• Excellent cost/performance ratio
• Contactable (groundable) to shield LF electric fields
• 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".

Silver products

• Silver products discolour with time and often already have discolorations right from the start. If you don’t want to accept discolorations, please choose Swiss-Shield® fabrics.
• Silver fabrics have a limited durability, depending on the frequency of movement.
• Our silver fabrics do not contain any nano silver, but a thick metallic silver coating.
