1. Military Shielding MaterialCopper nickel is a popular insulative metal due to its high electrical conductivity and effectiveness in signal reduction. Our faraday fabric is made of 20% copper nickel. It has a shielding rating from 10KHz to 30Ghz, surface resistance 0.05Ohm/sq, shielding effectiveness: 80 90dB, operating temperature 4℃ 85℃, thickness: 0.08mm, blocking 99% of wireless frequencies.<br> 2. High Electromagnetic ShieldingExcelling in radio signal blocking, the fabric screens mobile phone, wifi, Bluetooth, GPS, etc. significantly, providing up to 99.99% protection. It is suitable for RF/EMI/EMF/IF blocking, and is a super earthing/grounding fabric/anti electrostatic/esd /radiation/radiowave/microwave shielding electromagnetic fabric.<br> 3. Suitable for DIYFaraday fabric is moderately soft, ing a comfortable touch and being easy to sew and cut. It is suitable for use as lining. You can simply cut and sew to create various enclosures, covers, inner bags, etc. For example, you can make faraday cage, faraday wallet, faraday blanket and covers for phone, laptop, car keys and router.<br> 4. Work for SecurityFaraday fabric's unique blend of copper nickel creates a powerful shield against electromagnetic interference. It can be used to create signal proof rooms or tents, providing unrivaled protection. It is also used in high frequency electromagnetic applications such as industrial high frequency furnaces, mobile communication, signal transmission stations, medical instruments and other industries.<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
