Products: Elastomer Cored Knitted Wire Meshes | KE Series
General Information
Our KE Series 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 shielding effectiveness of all-mesh types.
In some cases a single mesh layer will be sufficient but in extreme cases, such as EMP, up to seven layers of 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 KC Series).
The core materials are usually sponges (neoprene, silicone, EPDM or PU) although for many applications a silicone or neoprene tube will 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. KE gaskets 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 KE Series cross-sections 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 (see KC Series) or round-with-tail mesh pre-fitted into aluminium mounting frames (see KM Series), which can be pre-drilled for easy fitting.

Examples / Notes
- Notes:
- Suffix #1= number of layers. E.g. (1) indicates one layer, default is 2 layers
- S/A = Self adhesive
- N/A = No adhesive
- Adhesive cannot be used on more than one layer
- Examples:
- KE-MST-60-0024 is 2.4 mm diameter round 2 x Monel layer over silicone tube
- KE-ANS-70-0032-0095-(1) S/A is 3.2 x 9.5 mm rectangular neoprene sponge with 1 x Aluminium mesh layers and PSA backing
