Conductive rubber gaskets

25 September 2019 Circuit & System Protection

A range of conductive O-profile silicone rubber gaskets is available from Holland Shielding Systems, developed for high-performance shielding up to 18 GHz and used where environmental and EMI screening is required but little space is available.

Four kinds of extrusion types are available: hollow, solid, cell rubber and rectangular. These extrusion cores can be covered with metallised fabric foil or they can be made out of conductive rubber. For optimal shielding performance a compression of 5-10% is recommended for solid elastomers and 10-50% for hollow extrusions and sponge rubbers.

Benefits of using these O-profiles include ease of fitting into grooves, deflection up to 50% and low closure force.
