✿【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%. ✿【99% Blocking Efficiency】Faraday fabric having nice conductivity, which can block unwanted frequencies from your phones, RFID and other wireless equipment. Highly electrically conductive, RF/EMI/EMF/IF blocking, super earthing/grounding fabric/anti-electrostatic/esd /radiation/radiowave/microwave shielding electromagnetic fabric. Reduce the radiation generated by 5G base stations. ✿【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. ✿【Cutable for DIY Various Products】Different sizes EMF protection fabric for your choice of needs of the product you want, if you are not good at making, you could just cover the faraday protection fabric over it. The fabric could be directly used as faraday blanket, phone case or computer covers, or made as wallet, gravida clothes, shielding tent, curtains and so on. ✿【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.
