Oriented Wires in Silicone & Fluorosilicone Rubber Product Overview A flat, sheet material, comprising a solid or sponge silicone rubber, embedded with Monel or Aluminium metal wires orientated perpendicular to its surface. Excellent RFI/EMI/EMP shielding performance is achieved as the material has a wire density of 140 wires/cm2 in solid silicone and 100 wires/cm2 in sponge silicone providing an environmental and RFI/EMI seal when clamped between two metallic surfaces. The wires are crimped to aid compression and are chemically bonded to ensure their retention in the silicone. They will also penetrate most oxide layers, ensuring a low contact resistance path when suitably compressed. This material also demonstrates EMP survivability. Application • A good solution for achieving RFI/EMI/EMP and Environmental sealing in a single gasket. • Ideal for use as access panels, seals, connector gaskets etc. • Good conformity to allow for uneven surfaces. Availability Kemtron is able to offer a wide variety of options as the material is cut in-house from large blocks, up to 228mm wide, using our high-speed slicer, enabling us to offer all thicknesses (subject to material type) to suit the customer’s exact design requirement. • Die- cut gaskets. • Large fabricated gaskets. • Virtually any flat shape can be produced. • Sheet material. • Strip material available in continuous lengths. • Self-adhesive backing to allow for easy assembly. • Can be fitted with compression limit stops or collars. • Small gaskets can be punched in one operation, keeping production costs to a minimum. • Larger gaskets can be produced cost effectively and without the constraint of sheet size limitation from strips of material fabricated into the required finished shape, thus avoiding waste material from the centre of the gasket. • A fluorosilicone version is available for use in environments where fuels / oils / hydraulic fluids and other contaminants are present. • Solid Silicone, for use in applications where higher compression forces allow for better environmental sealing. • Sponge Silicone requiring lower compression forces. 19-21 Finch Drive, Springwood Industrial Estate, Braintree, Essex CM7 2SF, United Kingdom.

Oriented Wires in Silicone & Fluorosilicone Rubber Product Overview (Continued) Design Considerations • It is important that this material is not overcompressed. If the design of the equipment does not allow for any mechanical method of preventing over-compression, the gasket should be fitted with built-in compression limiters, either metal stops fitted to the gasket, or metal collars fitted into each fixing hole. • There is no need for a conductive connection where strips are joined as the wires forming the EMC contact run vertically though the material; a waterproof seal is achieved by...
