✿【High Performance Shielding Material】Conductive fabric is 43 in wide, which metallic polyester fabric coated with 20% copper nickel, which creates a conductive grid that corresponds to the idea of a faraday cage. Surface resistance below 0.05Ohm/sq, average attenuation of 80-90dB from 10KHz to 30Ghz. Effective shielding of electromagnetic radiation, the shielding value reaches 99.99%. ✿【RF Signal Blocking】High shielding faraday fabric is made of copper+nickel+polyester that efficiently blocks wireless frequencies for blocking RF signals such as WIFI, GPS, bluetooth, RFID, and NFC. This guards you against potentially harmful RF signals, and enhances digital privacy! Keeps you away from harmful substances from cell phones, laptops and most other household appliances. ✿【From Secret Operations】The need to preserve, protect and extract digital information in devices and technological privacy makes the Faraday Fabric a must for government and military organizations. The fabric shield effectively secures communication and enhances digital isolation during discreet operations. It blocks electronic signals, defends against emps, and is ideal for signal-proof rooms or tents. ✿【Large Size for Crafting】The EMF blocking fabric enough for you to cut at will, you can cut it into different pieces or shapes according to your phone, card, laptop and more. The fabric could be directly used as faraday cage, faraday blanket, wireless router cover, anti-credit card skimming wallet, anti-theft car key fob bags, passport holders, phone pouches, laptop protective bags. ✿【Protects the Household】More and more homes are using these ultra-useful shielding Faraday fabrics to protect the family against exposure to undesirable electromagnetic radiation. Disruptive radiation may come from smart meters, laptops, TV screens, mobile phones, power outlets, routers, microwave ovens, nearby cell towers and so much more unsuspecting devices and appliances in or near homes.
