1.Polyester 2.TOPOFTHELINE COMPONENTS The Shielding Fabric is made up of polyester fiber, metallic copper and metallic nickel. Copper is a popular shielding metal because it high conductivity and effectiveness in reducing signals. Nickel is also widely used in shielding applications because of high electrical conductivity. 3.SUPERIOR SHIELDING PERFORMANCE Many governments and military organizations are also using our products. And this RF shielding fabric has obtained relevant professional certifications in the communications field. 4.EASY CUTTING AND SEWING Nontoxic; noncarcinogenic; not affected by humidity; maintenance ; can be cut, sewn, and taped like standard fabric easily to create DIY RF signal shielding enclosures and bags. 5.MULTIPLE USE Faraday Fabric can be used to make faraday bags, RF enclosures, EMF deflection, and signalproof room wallpapers or tents. Highshielding nickel and copper composition blocks WiFi (2.4 5GHz), Bluetooth, cell signals (4G LTE), GPS, RFID, radio signals, CellTowers, Microwave Signals, Phones, Smart Meters, Security Systems, Radar, Military Broadcast, etc and more with 80100dB shielding rating from 10Mhz to 5Ghz.
