Metal EMI Gaskets, and (BeCu) Beryllium Copper Springfingers
MESH STRIP EMI gaskets are compressible, all metal strips knitted into rectangular or round cross sections. As spring-like, interlocked loops, they are highly resilient. They are knit from either monel or Ferrex wire. These gaskets offer good aging properties, excellent tensile strength and spring like qualities. Mesh strip gaskets are available in rectangular, round, or double round with fin cross sections.
SPRINGMESH® gaskets are hollow, highly resilient spring gaskets, which offer the advantages of a mesh over core gasket without a core, and recovery of more than 70%. Compression set is less than 30% at 80% compression. They are available as cut to length.
COMBO® STRIP gaskets combine MESH STRIP in parallel with an elastomer weathering strip. Recommended for applications requiring a weather seal in addition to EMI shielding, they are available with high tack, long shelf life adhesive backing . Compression set and closure is in the 25 to 100 psi range, although options are available for sealing pressures as low as 10 psi.

SPRING-LINE beryllium-copper gaskets combine high levels of EMI shielding effectiveness with spring-finger wiping and low closure force properties. The high performance qualities of beryllium-copper – high tensile strength, excellent anti-corrosion properties, and superb electrical conductivity – make it an ideal material for EMI shielding over a broad frequency range. SPRING-LINE shielding gaskets are available standard in bright tin, brightcopper, and bright nickel finishes, and others upon request. Strips can be soft soldered or resistance welded without damage to their working surface. SPRING-LINE profiles can be installed by edge mounting, slot mounting, using a track and plastic rivet system or by pressure-sensitive adhesive. |

POLASHEET and POLASTRIP gasketing are composite EMI shielding and weather sealing materials. Either solid or sponge silicone may be specified as the weather seal. In POLASHEET gasketing, individual monel or aluminum wires embedded in the silicone and oriented perpendicular to mating flange surfaces provide the EMI shielding. Wires are crimped for resiliency. Solid silicone POLASHEET gasketing is available with high-tack pressure-sensitive adhesive backing. In POLASTRIP gasketing, EMI shielding is provided by monel or aluminum knitted wire mesh embedded in silicone. POLASHEET and POLASTRIP gasketing with solid silicone weather seal are recommended for sealing under high pressure conditions. The silicone seal is rated for use at temperatures from –70°F (–56.7°C) to +500°F (+260°C). Sponge silicone is used only for pressures below 5 psi (0.03 MPa) and for rain, drip, dust and ventilating air seals. |
