1. of the line components The shielding fabric is made of polyester fibres, metallic copper and metallic nickel. Copper is a shielding metal as it offers conductivity and effectiveness in reducing signals. Nickel is also widely used in shielding applications due to electrical conductivity. 2. shielding performance Many governments and military organisations also use our products. This RF shielding fabric has received relevant professional certifications in the communication field. 3. Easy cutting and sewing Nontoxic, noncarcinogenic, not affected by humidity, maintenance, can be easily cut, sewn and glued like standard fabric, to create DIY RF signal shielding housing and bags. 4. MULTIPURPOSE Faraday fabric can be used to make Faraday bags, RF housing, EMF distractions and Signalproof wallpapers or tents. shield nickel and copper composition blocks WIFI (2.4 5 GHz), Bluetooth, cell signals (4G LTE), GPS, RFID, radio signals, cell towers, microwave signals, phones, smart meters, security systems, radar, military transmissions, etc. with 80100 dB shielding rating from 10 MHz to 5 GHz.
