Conductive Foam
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.
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.
Features and Benefits
- RoHs compliant
- Improved Z-axis conductivity increases shielding effectiveness to over 90 dB across a wide ranges of frequencies
- Available in 0.039" ( 1mm), 0.060" (1.5mm), 0.079" (2 mm), 0.098" (2.5 mm), 0.125" (3.2mm) thicknesses and widths down to 0.250" (6.4mm)
- Wide compression ranges of up to 60% of original uncompressed thicknesses
- Available in both UL94 HB and V0 rated versions
- Available in many standard configurations including D-subs, USB port, IEEE 1394, SCSI and RJ 11 connector. (Also available in sheet stock and rectangular profiles)
- Custom die-cut versions are available
- Die-cut I/O designs, rectangular strip gaskets and backplane gaskets can be supplied with or without conductive adhesive
- Low compression set ensures long term gasket performance
Applications
- Desktop computers
- Servers
- Routers
- Notebook computers
- Telecommunications equipment
- Aerospace equipment
