Structure with foam as its intermediate layer, offering a suitable material for EMI shielding and absorbing Gasket
|
|
This conductive foam is made of polyurethane foam plated with copper and nickel. Compression is 25% to 75%. It will return nearly to nominal height when released. It is coated with conductive polyurethane to protect the foam from the environment and to prevent burrs when cutting. The conductivity is excellent in all directions X, Y and Z. It is flame retardant and RoHS compliant.
The conductive foam is characterized by:
- Availability in thicknesses of - 1, 2, 3, 4 and 5 mm,
(Other sizes on request).
- Excellent electric conductivity throughout the surface
across the thickness
- Excellent electromagnetic shielding effect
- High workability for adhesion
- Easy die cutting, kiss cutting and slitting
- Size - Sheet Type: Max 450 x 450 mm,
(Other sizes on request).
Applications:
- Mobile phone
- Noise filter core
- Cable tray
- Shielded rooms
