Use these foam half rounds as a cushioning bumper, as well as in packaging applications. This polyethylene foam has closed-cell construction, which restricts water, air, and gases from being absorbed.

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.

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.

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.

Gaskets that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping.
