    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. They compress to fill gaps and complete a grounding path around doors and access panels.

    Polyurethane Foam

    Sheets work well between two flat surfaces.
    Polyurethane Foam—Polyurethane foam gaskets are covered with either a conductive nickel/copper braided fabric or conductive aluminum foil. A nonconductive adhesive holds them in place. To protect sensitive equipment, they block at least twice as much interference as urethane foam gaskets. Cut these gaskets to length with scissors.
    Adhesive Backing—Adhesive-back gaskets stick to flat surfaces.
    UL 94 V-0—Gaskets that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping.

    Half Round

    Half-round gaskets work well in grooves. Use a gasket slightly thicker than the depth of the groove; it will compress to fill the gap.

To protect sensitive equipment, they block at least twice as much interference as urethane foam gaskets. Cut these gaskets to length with scissors.

    Beryllium Copper—Beryllium copper gaskets withstand repeated compression and decompression over time, so they’re often used with doors that regularly open and close. They’re also known as fingerstock gaskets.
