Elastomer Cored Knitted Wire Meshes | Gaskets, Lengths & EMI Shielding

General Information

Our elastomer cored knitted wire meshes consist of two layers of knitted wire over a low-closing-force rubber or elastomer core and offer the same EMI shielding effectiveness of all-mesh types.

In some cases a single knitted wire mesh layer will be sufficient but in extreme cases, such as EMP, up to seven layers of knitted TCS will be used. Cored knitted mesh is sometimes combined with an environmental seal to provide IP ratings [PDF] of 65 or above, depending on the materials used and the suitability of the mating surfaces (see Knitted wire mesh with environmental seal).

The elastomer core materials are usually sponges (neoprene, silicone, EPDM or PU) although for many applications a silicone or neoprene tube can be specified.

Applications

In comparison with 'solid' mesh types, elastomer cored knitted wire meshes have a high degree of recovery so they are more suitable for use on doors and covers that are reguarly opened and closed. The closing pressure is much lower and a good EMI shield is formed even where there are minor surface irregularities. Gaskets made from knitted wire mesh over an elastomer core will also provide limited environmental sealing, particularly against dust. Where there are hazardous conditions flurosilicone or other special formulations can be specified to meet your requirements.

Elastomer cored knitted wire mesh gaskets can either be retained in a groove or channel or fixed with adhesive (the wire contact points can penetrate a thin film). To facilitate clamping or riveting, 'round-with-tail' and 'double-round-with-tail' sections are available. Many variants are available with a pressure sensitive adhesive backing applied across part of one face for easy fitting.

Alternative fixing methods use tandem or 'Twinstrip' environmental seals or round-with-tail mesh pre-fitted into aluminium mounting frames, which can be pre-drilled for easy fitting.
