Conductive Foam Construction
Conductive Foam in a rectangular profile design provides an
excellent alternative to standard Fabric-Over-Foam profile gaskets
in low shear applications. Supplied in UL94 HB or UL94 V0 fire
rated material, with or without conductive adhesive, Conductive
Foam is a cost-effective solution for many perimeter shielding and
grounding applications.
