✿【Highest Quality Components】Faraday cloth is made of polyester, metallic copper and metallic nickel. Copper nickel is a popular insulative metal due to its high electrical conductivity and effectiveness in signal reduction. Surface resistance: below 0.05Ohm/sq, average attenuation of 80-90dB from 10KHz to 30Ghz. Effective shielding of electromagnetic radiation, shielding value reaches 99.99%. ✿【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. ✿【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. ✿【Convenient Easy to Use】Copper fabric is a soft, lightweight material that's a breeze to work with...of versatile shielding material. Used for making radiation protection curtains, radiation protection mobile phone pocket, passport cover radiation protection computer cover, mainframe chassis cover. You can even use it to make gravid clothes, blankets. ✿【Importance of EMF Protection】Our health is threatened by electromagnetic waves every day, and with the advancement of technology, the means of hacker attacks are becoming increasingly complex. Our electronic device information is easily stolen by others. At this point, EMF protection cloth is very important as it can protect us from the radiation of various electronic devices.
