✿【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%. ✿【Superior EMI Shielding】Faraday fabric is used for manufacturing faraday bag, RF shells, EMF deflection, and signal protection rooms or tents. High shielding nickel and copper components block WiFi (2.4 and 5GHz), Bluetooth, cellular signals including 5G networks, GPS, RFID, and radio signals. Enjoy enhanced digital privacy and protect yourself from potentially harmful RF signals with ease. ✿【Satisfactory Practicality on Various Occasions】Faraday fabric offers reliable protection against high frequency electromagnetic radiation from sources such as industrial equipment, communication towers, and household appliances. and it's not just for personal use - this is the same material used by military and law enforcement to block signals from cellphones, WIFI, bluetooth, and GPS. ✿【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. ✿【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.
