Electrically conductive foam 5770

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

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.


Characteristics:

  • Available in thicknesses of 1, 1.5, 2, 2.2, 3.0, 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, kiss cutting and slitting
  • 950 mm roll width

Applications

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