    Silver Twin, HF Shielding Fabric, Cotton/Silver Tissue, 57dB

    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: 150cm   ±2cm
    • Length: Available by the meter
    • Attenuation: 57 dB at 1 GHz
    • Colour: Frontside light gray, backside silver.
    • Raw materials: 50 % cotton, 35 % polyester, 15% silver
    • Weight: 150 g/m²
    • Dimension stability: ±3%
    • Surface conductivity: 0.25 ohm / square

    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.

    Shielding attenuation:
    All shielding attenuation values are valid at 1GHz. Measurement according to ASTM D4935-10  /IEEE Std 299-2006 / IEEEE Std 1128-1998 / ASTM A698/A698M-07.






    Cleaning in a washing machine at 30°C is possible No handwashing!
    For allergic persons: Every new fabric smells! Always wash before its first usage!

    Discolouration: Fabrics with silver threads will discolor over time! The reasons for this are direct sunlight, heat from the radiator, splashes from cleaning water, sweat,  etc. Stained places have no negative effects on the screening attenuation at all and they are no quality defect!

    Please note: The price is valid per m² (square metre), not per running metre!
    Minimum order quantity: 1.5m² (= 1 running metre)

    This product is cut off a large roll according to customer specifications. A return is not possible!
