1. Highquality material: highperformance conductive fabric Faraday fabric made of 20% copper/nickel 80% polyester. Signals with 80 90dB average attenuation from low 10kHz up to 30GHz. 99% blocking of radio frequencies, resistance below 0.05 Ohm/sq. 2. Effective shielding performance Nickelcopper blend prevents WiFi and mobile signals from being passed through, EMI shielding fabric can block most electromagnetic signals, such as 5G, GPS, EMI, RFI, EMF, electromagnetic interference, electromagnetic field, radio frequency signal, global positioning system, create situations for you. 3. Avoid leaking information – as an insert in the wallet or handbag, Faraday pockets to protect your credit cards from data theft. Wrap the phone tightly in several turns without small gaps, is effective to shield the signal (WiFi, Bluetooth, GPS, RFID etc.). Friction resistance, good ductility. 4. Wide range of uses This signalshielding fabric can be used for many products, maternity clothing, radiation protection suits, radiation protection curtains, Faraday fabrics, canopies, films or use for Faraday blankets, routers, microwave ovens.
