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.
