The Most Important Facts about Conductive Tapes and Shielding Fabrics

When it comes to shielding fabrics and conductive tapes, there is a lot of important information that you need to consider because electromagnetic interference is such a looming problem for modern electronics. Engineers need innovative safeguards that protect sensitive equipment to meet the standards of modern electronics. If this does not happen, electronic devices run the risk of failure. Shielding fabrics and conductive tapes are a common technique used to protect against EMI and RFI.

EMI shielding fabrics are designed to absorb and reflect harmful radio frequencies. It is important to keep in mind that the absorption rate depends on the thickness of the shielding material. Even those shielding tapes and fabrics absorb EMI and RFI; these materials also reflect harmful interference. Reflection is the largest determining factor for high-frequency signal attenuation. To achieve the highest levels of reflection, you need to determine the proper fabric shielding material. Reflective RFI shielding contains highly conductive metals, such as copper and nickel. For special cases, engineers use a combination of both materials. Make sure to ask about the difference between non-adhesive, hot melt, and conductive adhesive backing options.

RFI EMI shielding materials offer perfect sealing for joints, seams, enclosures, panels, and frames. In special circumstances, shielding fabrics are used in architectural shielding finishes (ceiling/walls of shielding rooms). EMI RFI Shielding protection ranges from 70 dB up to 10 GHz.
