These gaskets absorb electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent inaccurate signals, flickering displays, and other electrical problems. 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. Adhesive-back gaskets are wrapped with conductive aluminum foil and stick on with a conductive adhesive. They meet UL 94 V-0, so they self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping. Plain-back gaskets are made with conductive silver wire. They meet UL 94 HF-1, which means they stop burning within two seconds if they catch on fire and won’t spread the fire by dripping.

Polyurethane foam gaskets are covered with a conductive nickel/copper braided fabric. A nonconductive adhesive holds them in place. To protect sensitive equipment, they block at least twice as much interference as urethane foam gaskets. They meet UL 94 V-0, so they self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping. Cut these gaskets to length with scissors.

Silicone rubber sheets are embedded with conductive nickel wire. They block the most interference of our shielding gaskets and also seal out moisture. One side is smooth; the other is rough to help adhesives stick. They meet AMS, ASTM, and military standards for materials.
