- Information about RF Radiation Shielding Fabrics -
Electromagnetic shielding that blocks radio frequency electromagnetic radiation is known as RF radiation shielding. The shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields.
The principle of RF shielding is to using a conductive enclosure to block electrostatic fields. Typical conductive materials used for shielding is metal. With the latest technology innovations the metal and silver fiber blend fabrics become two popular types of shielding fabric used for making shielding clothes in nowadays market. 
1. The metal (copper, nickel etc.)  fiber blen fabric contains no harmful substances. It is effective RF shielding and provides 30-35dB RF radiation attenuation from 10M Hz to 3GHz according to independently tested results.  
2. The silver fiber blend fabric is a very conductive, and provides super shielding performance with up to 56 dB RF radiation attenuation from 10M Hz to 3GHz according to independently tested results.
