EMF Blocker Material Faraday Fabric EMI RFID/RF Shielding Anti Radiation RF Blocking for RF,EMI,WiFi,Military Grade Tent Fabric,Blanket,silver 8m

20% Copper/Nickel Material：High conductive faraday fabric, surface resistance 0.03-0.05Ohm, average attenuation of 80-90dB from 10KHz to 30Ghz. copper+nickel+polyester, this creates a conductive grid that corresponds to the Idea of a faraday cage. fabric sheet is 43in wide. RF Signal Blocking：High-shielding nickel and copper composition blocks WiFi, bluetooth, cell signals including 5G networks, GPS, RFID, EMI, RFI and EMF radiation shielding. control space electromagnetic interference, anti-electronic information leakage, to ensure information security. Easy to Use：According to your shielding requirements make RFID anti-theft wallets, card bags, faraday bags, car key bag, phone wifi shield bag, waist bags, passport covers and so on. reduce electronic information leakage, ensure that the fabric completely wrap the item and not to leave any small openings for best results. Wide Range of Use：This EMF protection fabric can well protect us from the radiation of various electronic devices, smart meters, laptops, TV screens, routers, microwave ovens. making faraday curtain, maternity clothes, blanket, tents and so on. Importance of EMF Protection: Our health are be threatened by electromagnetic waves every day, with the advancement of technology, the means of hacking are also becoming more and more sophisticated. our electronic device information can be stolen by others easily. at this time, the emf protection appears very important, can protect us from the radiation of various electronic devices.
