EMI/RFI Shielding Gaskets
These gaskets absorb electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent inaccurate signals, flickering displays, and other electrical problems. Made of foam or rubber combined with conductive material, they compress to fill gaps and complete a grounding path around doors and access panels.
Sheets work well between two flat surfaces.
Urethane foam gaskets block EMI and RFI in most applications. Plain-back gaskets are made with conductive silver wire. They meet UL 94HF1, which means they stop burning within two seconds if they catch on fire and won’t spread the fire by dripping.
