Conductive Elastomers – Extrusions, O Rings, Flat Gaskets and Sheet Material

Conductive elastomers are loaded with highly conductive fillers such as nickel graphite, silver plated aluminium, silver plated copper and pure nickel. Available in silicone, or fluorosilicone for resistance to fuel oils and solvents, conductive elastomers are available as extruded profiles, moulded components, flat sheet or as O rings. Conductive elastomers give superior EMI shielding combined with environmental sealing. The choice of conductive fillers ensure electrochemical compatibility. Applications Electronic enclosures Military equipment Control units Medical electronic equipment Conductive Fillers Nickel plated graphite – high quality, cost effective and easy to extrude or mould Silver plated aluminium – used for high frequency applications, and is a lighter weight than some other materials Silver plated copper – excellent EMI shielding performance across all frequencies, but higher cost and increased weight Nickel – widely used in military applications, but generally replaced by nickel plated graphite Material Selection Silicone – retains its elastomeric properies over a wide range of temperatures. Does not degrade in oxygen or ozone presence. Fluorosilicone – offers superior chemical resistance Technical Specification Temperature range -55/+200 degrees C UL94V0 flame retardancy Thickness from 0.5mm Choice of metal fillers for galvanic compatibility Conductive self adhesive backing on sheet form Fothershield manufacture from a wide range of standard tooling, but can also manufacture to customer’s specification.
