Knitted Wire Mesh Over an Elastomer Core Product Overview This product is a knitted wire mesh over an elastomer core such as neoprene or silicone cellular profile or tube. Usually this consists of 2 layers of knitting over the elastomer core but small sections 1.5mm diameter requiring only 1 layer. The knitted mesh is then formed into the selected profile making a continuous gasket strip which is flexible and compressible and which makes an excellent RFI/EMI/EMP gasket. Application In addition to making an excellent EMI/RFI/EMP shield between two metallic surfaces the choice of wire mesh material available also allows for a good galvanic match with mating flanges, thereby limiting the possibility of corrosion between gasket and flange. Further, the elastomer core of the gasket allows it to be compressed using low to medium force conforming to uneven surfaces and recovering well after use. Design Considerations • Consideration should be given to the termination of cut mesh ends. Sometimes loose wires are evident after cutting. Kemtron are experts at mesh termination however if you choose to cut the mesh yourself loose wires can be avoided by: – Dipping the end in glue, – Spot welding the cut end. – Sewing the cut mesh end. • Groove gaskets such as ‘O’ rings. • ue to its resiliency and low compression force, D ideal for use in situations where repeated opening and closing operations are necessary. • Compression forces required to allow good contact. Also the rigidity of the host metalwork. • Galvanic compatibility. Select from a choice or wire. • Water and moisture sealing is not possible with this product. However, it does offer a limited dust seal. Availability • In continuous lengths. • Cut to length. • Fabricated into finished gaskets. • Variety of profiles and sizes. • Fabricated gaskets. • Selection of wire to meet galvanic compatibility requirements. • arge selection of elastomer cores are available L to meet conditions such as temperature range, compression set, compression force. • lthough round or rectangular cross sections are A the most commonly used, other sections can be made to custom designs. • here EMP protection is needed, a minimum of W 7 layers is recommended. Additional layers can also be added depending on the application of the equipment and degree of shielding required. • Self adhesive backing is not recommended with this version of mesh. 19-21 Finch Drive, Springwood Industrial Estate, Braintree, Essex CM7 2SF, United Kingdom.
