Characteristics
SILVER-TWIN is a compact cotton/polyester 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
Technical data
- Width: 150 cm, +/- 2 cm
- Length: Available by the meter
- Attenuation: 57 dB at 1 GHz
- Color: Frontside light gray, backside silver. Attention: Due to silver oxidation the front side can have very slight discolouration, this is no quality defect!
- Raw materials: 50 % cotton, 35 % polyester, 15 % silver
- Weight: 150 g/m²
- Dimension stability: +/- 3 %
- Surface conductivity: 0.25 ohm / inch (2.54 cm)
Shielding attenuation Care
Grounding
Due to the surface conductivity this fabric can be grounded to shield low frequency (LF) electric fields. For professional grounding we recommend our Grounding-Plug EST.
The shielding attenuation is regularly tested in our own laboratory or by Professor Dipl.Ing. Pauli at the University of the German Federal Armed Forces in Munich due to the standards ASTM D4935-10 and/or IEEE-STD-299-2006. The line in the diagram stands for the radial direction of polarisation (both directions, horizontal/vertical) and indicates the attenuation achievable in practice. You find the expert report above.
