- High-performance shielding fabric: 20% nickel-copper, 80% polyester. Shields from 10 kHz to 30 GHz with good conductivity. Surface resistance 0.03-0.05 Ohm/sq, shielding rate ≥80-90 dB, blocks 99% of wireless frequencies. Thickness 0.08 mm, width 110 cm. - Premium signal blocking: high-shielding nickel and copper blocks high-frequency EM signals. Conductive fabric reduces WLAN, mobile, and RF signals, shielding WiFi, Bluetooth, GPS, RFID, and other signals. EMF shielding fabric to protect against potentially harmful frequencies. - Faraday protection made easy: use the long fabric to create your own Faraday cage. Easy to cut and sew to fit smartphones, laptops, WiFi-sign pockets, car keys or cards. Helps prevent information loss and information theft. - Wide applications: suitable for anti-static fabrics, wireless measuring devices, shielding curtains to reduce EMP and EMI. Also adaptable for Faraday blankets, routers, mobile computers, microwave ovens, signal-resistant rooms or tents.
