✿【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%. ✿【Effective EMF/EMI Protection】Conductive fiber fabric with high shielding, high conductivity and good anti-radiation performance, can effectively reduce and block electromagnetic waves and radiation such as RFID, bluetooth, GPS, WIFI, EMI, EMF and EMP to protect your health and privacy, avoid personal information leakage from electronic devices and ensure information security. ✿【For Commercial and Personal Use】Faraday fabric from household appliances to global positioning system. 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. ✿【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.
