Conductive Foam

Conductive foam is a polymeric foam combined with conductive material which can make it have permanently conductive properties. It offers a quicker transfer of any static charge to a grounding source or adjacent conductive material. The common polymers that can be made into conductive foams are polyurethane (PU), ethylene-vinyl acetate (EVA), polyethylene (PE), etc.

Basic Parameters

Our conductive foam is made of polyurethane foam coated with copper and nickel. The compression is 25% to 75%. The maximum application temperature is between 60 and 70℃. Its conductivity is excellent in all directions (X, Y, and Z).

Special Properties

• High compressibility and resilience—High compressibility means that foam has a wide range of applications and can be filled into small gaps. Resilience is a sign of foam being compressed multiple times or for a long time.
• achinability—Easy die cutting, kiss cutting and slitting. Conductive foam can be cut into any shape according to your CAD drawing.
• Excellent shielding effectiveness—When the frequency of electromagnetic wave is between 100Mhz and 1GHz, conductive foams with different thicknesses offer different shielding effect:
  1.5 mm thickness, 80-83dB
  2.4 mm thickness, 88-104dB
  3.5 mm thickness, 80-103dB

Applications

Conductive foam is a commonly used conductive material in the electromagnetic compatibility design and rectification of electronic products. It can not only absorb the dimensional tolerances of the product structure, fill the gaps between the components, but also provide a stable conductive connection. The excellent mechanical and electrical properties make it an effective solution for tough shielding, grounding, and sealing problems.

As these advantages, conductive foam is widely used in electronic computers, LCD display, laser copier, high speed printer, communication equipment, mobile phones, satellite communications, medical apparatus and instrument, high pressure machine testing, instrumentation, gasket/baffle, socket electronic equipment, seismic conductivity of the package.
