Products: Knitted Mesh | KP Series

General Information

Knitted wire meshes are produced from a single continuous filament and produce very high levels of EMI shielding performance when evenly compressed between two metallic contact surfaces.

Our KP Series meshes are available in four basic wire types – Monel, Aluminium, TCS (Tinned Copper-clad Steel) and Stainless Steel. Each has it's own specific characteristics but TCS is generally regarded as the most suitable for EMP shielding.

Applications

Because knitted wire meshes are not as resilient as elastomer cored meshes (see KE series), and so will eventually take a compression-set, they are generally used where the panel mating surfaces are permanent or fixed.

KP meshes provide only limited environmental sealing so are normally used for applications that are not exposed to the elements unless they are protected by a further external elastomeric seal (see KC Series). They do, however, have a long service life and a high temperature tolerance.

For optimum effectiveness knitted mesh gaskets should be compressed by 20 – 25% of their relaxed height. If surface irregularities prevent this an elastomer cored mesh (KE Series) would be more suitable.

Gaskets can either be retained in a groove or channel or fixed with adhesive (the wire contact points can penetrate a thin film), welding or soldering. To facilitate clamping or riveting, 'round-with-tail' and 'double-round-with-tail' sections are available.
