- Military-Grade Shielding Material: Constructed from 20% copper nickel, our faraday fabric is designed for superior electrical conductivity and signal reduction. It features a shielding rating from 10KHz to 30GHz, with a surface resistance of 0.05 Ohm/sq and an impressive shielding effectiveness of 80-90dB. Operating temperature ranges from -4℃ to 85℃, and with a thickness of just 0.08mm, it blocks 99% of wireless frequencies. - 99% Signal Blocking Efficiency: This fabric combines metallic copper, metallic nickel, and polyester fibers to effectively block electromagnetic fields (EMF) and electromagnetic interference (EMI). It protects against harmful frequencies, safeguarding your sensitive information from cellphones, WIFI, Bluetooth, and GPS signals. It also provides protection against electrostatic discharge, radiation, and microwave interference. - Versatile DIY Applications: Create custom solutions tailored to your needs. Use this shielding fabric to line pockets, craft RFID-blocking wallets, wrap credit cards, or line hats. It can also be fashioned into pouches for cell phones, smart keys, or any devices that transmit or receive signals, allowing for personalized shielding based on your requirements. - Comprehensive Electromagnetic Protection: This fabric delivers robust protection against electromagnetic radiation from various sources such as transmission towers, communication base stations, and WIFI routers. Trusted by law enforcement and military professionals, it effectively blocks electronic signals, defends against electromagnetic pulses (EMPs), and is perfect for creating signal-proof environments, such as secure rooms or tents. Experience the peace of mind that comes with reliable shielding against EMF and EMI.
