Elastomer cored knitted wire mesh

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.
