Conductive foam offers an innovative approach to traditional shielding and grounding by providing X, Y, and Z-axis conductivity, which enhances the shielding effectiveness required to meet the increasing microprocessor speeds of today’s computer, telecommunications, and aerospace equipment.

This conductive foam is made of polyurethane foam plated with copper and nickel. Compression is 25% to 75%. The temperature range is between -10 and 85 °C

The material will return close to normal height when released. The foam is coated with conductive polyurethane to protect it from environmental influences and to prevent burrs when cutting. It is RoHS compliant.

Conductive Foam is designed for low-cycling applications such as input/output (I/O) shielding and other non-shear standard connectors. Rectangular strips are available for perimeter gasketing applications.

Electrically conductive foam die cut

Conductive foam kiss cut according to customer's requirements. The conductive foam pieces can be easily removed from the release liner and be stuck into place with the electrically conductive adhesive.

We can cut several layers of conductive foam to create cavities.
