Woven & Expanded Wire in Elastomers

A composite of metal wire mesh impregnated with an elastomer, creating a highly conductive and resilient gasketing material for EMI/RFI shielding and environmental sealing applications.

Download Datasheet

Woven aluminium wire, expanded aluminium or expanded Monel sheet, impregnated with an elastomer filler – Silicone, fluorosilicone or synthetic rubber or expanded Monel sheet without elastomer filler.

The conductive metallic surfaces of the material provide an excellent low resistance contact whilst under the correctly designed conditions the rubber component ensures effective dust and moisture sealing.

The exposed metallic points on the woven product, where the weave of the wire overlaps, create approximately 80 contacts per cm² whilst the raised edge on the expanded sheet product creates approximately 20 contacts per cm².

Provides an economic approach to gasketing flat surfaces where unevenness does not exceed 0.10mm and or where material thickness constraints occur. Particularly suited to small thin gaskets such as MIL type connectors etc. Other thin gaskets can be made in-house using specialist cutting methods and the material can also be supplied as continuous sheet for your own production purposes. Fluorosilicone versions are suitable for applications where fuels / oils / hydraulic fluids and other contaminants are present.
