1. High performance material: Conductive shielding fabric is 110 cm wide and is made of 20% copper/nickel and 80% polyester. It has an average attenuation of 80 90 dB for signals from low 10KHz up to 30GHz. Blocks 99% of radio frequencies, with a resistance of 0.05 Ohm/sq. 2. Trusted performance: High shielding nickel and copper composition blocks high frequency electromagnetic signals. The conductive fabric blocks and reduces WiFi, mobile phone and RF signals. It can anti electrostatic/radiation/radio waves/microwave shielding electromagnetic substances to protect you from radiation. 3. Stop card identity theft: According to shielding requirements, it can be made into RFID anti theft wallets, card pockets, car key bags, mobile phone WiFi sign pockets. It can be used as an insert in the wallet or handbag, and Faraday pockets to protect your credit cards from data theft. 4. Wide range of applications: Used for electromagnetic high frequencies, such as industrial high frequency roads, mobile communications, signal transmission stations, medical instruments and other industries, tents, routers, microwave ovens and many other devices and household appliances.
