5770 series Conductive Foam

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%. 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 it from environmental influences and to prevent burrs when cutting. Its conductivity is excellent in all directions (X, Y, and Z). Conductive foam is fire retardant as well as RoHS compliant.


The conductive foam is characterized by:

  • Available in thicknesses of 1, 2, 2.2 and 3.4 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, kiss cutting and slitting
  • Size - Sheet type: max 950 x 950 mm (other sizes on request).

Applications

  • Mobile phone
  • Noise filter core
  • Cable tray
  • Shielded rooms
