1. quality material: performance conductive Faraday fabric made of 20% copper/nickel 80% polyester. Provides 80 90dB average signal attenuation from low 10kHz up to 30GHz, blocking 99% of radio frequencies with resistance below 0.05 Ohm/sq. 2. electromagnetic shielding – Effectively blocks RF signals like mobile phone, Bluetooth, WiFi, and GPS. Ideal for RF protection and EMI reduction, including radiation from 5G base stations. for scenarios requiring secure electromagnetic signal blocking. 3. Prevent data theft – Use as an insert in wallets or handbags to shield credit cards from skimming. Wrapping phones tightly (without gaps) effectively blocks WiFi, Bluetooth, GPS, and RFID signals. Features abrasion resistance and ductility. 4. Versatile applications – Can be used to create covers or mesh barriers for shielding needs. Suitable for making Faraday curtains, blankets, tents, and more to protect smart meters, TV screens, outlets, routers, microwaves, and other household devices.
