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
•t A good solution for achieving RFI/EMI/EMP and
Environmental sealing in a single gasket.
•t Ideal for use as access panels, seals, connector
gaskets etc.
•t 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.
•t Die- cut gaskets.
•t Large fabricated gaskets.
•t Virtually any flat shape can be produced.
•t Sheet material.
•t Strip material available in continuous lengths.
•t Self-adhesive backing to allow for easy assembly.t
•t Can be fitted with compression limit stops or collars.

•t Small gaskets can be punched in one operation,
keeping production costs to a minimum.
•t 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.
