Conductive Elastomers
Electrically conductive elastomers cover an important area in the field of EMC shielding when an additional environmental shielding is required.
They consist of an elastomeric binder (silicone or fluoro-silicone), which is supplied with different fillers depending on the desired shielding performance and contacted materials (prevention of corrosion). We are happy to advise you on the selection!
Electrically conductive elastomers are produced in sheets, as moulded or extruded sections and can also be printed onto surfaces.
Depending on the application and the required profile, o-rings can be supplied as moulded parts or vulcanized from extruded profiles.
Extruded round profiles can be produced with very small diameters and are therefore well suited for narrow-walled housings.
