Conductive foam is used to prevent damaging voltages and electrostatic discharges and thus protect both the electronic components and also the employees at ESD workplaces. Sections of conductive foam can be used flexibly for this purpose. They are suitable for instance for use as overlays on the worktop, as upholstery padding for seat squabs or in the field as an inlay in service cases or transport cases. Electronic components with projecting connectors can be inserted into the foam for packaging purposes. This protects them both against electrostatic discharges and also against mechanical shocks.
