0.020" Gaskets | McMaster-Carr

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

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.

Flame-Retardant Silicone Rubber Sheets

Create a barrier against fire and smoke. These sheets meet FAR 25.856 and UL 94 V-0 for flame retardance, so they emit extremely low levels of smoke when exposed to fire. Silicone, also known as polysiloxane, has a wide temperature range. This makes it good for applications like glass manufacturing and automotive components. Silicone also has excellent weather resistance against sunlight, ozone, and water.
