Radio Frequency (RF) Shielding Information

RF Radiation Shielding

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.

RF Radiation Shielding Fabrics

Typical conductive materials used for shielding is metal. High-tech metal and nano- silverr blend fabrics are popular shielding fabrics for making shielding clothes in nowadays market. Shielding effectiveness of OurSure textile products was tested by accredited institutes and verified to have up to 30-35 dB shielding effectiveness for RadiProtect Metal products made with 25%-35% metal blend fabrics, up to 56 dB shielding effectiveness for RadiProtect Silver products made with 50% silver blend fabrics, and up to 70 dB shielding effectiveness for RadiProtect Silver products made with 100% silver blend fabrics in the frequency range from 10MHz to 3GHz and beyond. The higher dB value, the higher shielding effectiveness it gives. 100% silver blend fabrics provides the best RF shielding effectiveness.

Please note that the cell phone test is a demonstration of effectiveness only. RF shielding result may vary by cellular network, geographic location and phone model. Even when a majority of radiation is shielded, the radiation levels may be high enough in some high-power cellular networks that a small fraction of signal will allow reception and register a signal on your phone.

100% Silver blend products are suggested for completely shielding cell phone signal.
