Electrically Conductive Foam

Electrically Conductive Foam 5770

Structure with foam as its central layer, suitable for EMI shielding and absorbing gaskets

This Conductive foam is made of polyurethane foam coated with copper and nickel. Compression is 25% to 75% and the maximum application temperature is between 60 and 70 degrees Celsius.

The material will return to almost its original height when released. The foam is covered with a layer of conductive polyurethane to protect from environmental influences and to prevent burrs when cutting. Its conductivity is excellent in all directions (X, Y, and Z). This Conductive Foam is fire retardant as well as Restriction of Hazardous Substances (RoHS) compliant.

Characteristics:

Available in thicknesses of 1, 1.5, 2, 2.2, 3.4 and 5 mm
Several layers can be joined together for thickness, on request
Excellent electric conductivity throughout the material
Excellent electromagnetic shielding effect
High workability due to adhesion
Easy die cutting and slitting
950 mm width

Applications:

Mobile phone
Noise filter core
Cable tray
Shielded rooms

Conductive foam in various thicknesses and cut to shape

Conductive foam can be cut into any shape according to your CAD drawing. The round parts have a copper and nickel plated non-woven top layer – this is optional

Conductive foam has an open cell structure which makes it easy to compress

Conductive foam can be 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

Very thin (1mm thick) Conductive foam cut according to customer requirement
