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, telecommu-
nications, 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 gasket-
ing applications.
All dimensions shown are in inches (millimeters) unless otherwise specified.
