✿【Military Conductive Material】20% copper nickel fabric serves as a military grade protective material, ensuring shielding against frequencies. Temperature from as low as -4℃ to as high as 85℃, faraday fabric retains its shielding effectiveness. Its frequencies shielding range of electromagnetic field and electromagnetic is from 10KHz to 30Ghz. Shielding efficiency reaches 80-90dB. ✿【Reduce Radiation】Conductive fabric absorb electromagnetic fields and waves as known as EMF, from devices and outlets. Excellent for absorbing radiation from smart meters and other EMF sources. Nickel copper blend prevents most WIFI, cell signal, and radiation from going through. Wrap the devices or put is in the front of your laptop, the RFID fabric will keep the radiation totally away from you. ✿【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.
