O-ring seal / aluminum / EMI shielding / oriented-wire
Metal Textiles Europe
Metal Textiles POLA Oriented Wire gasket material is a combination of EMI/RFI and pressure sealing material available in strip, sheet, or die-cut form. Wires of Monel or Aluminum, oriented perpendicular to the mating surfaces provide EMI attenuation, and the surrounding matrix of silicone or fluoro-silicone elastomer provides a pressure seal, when it is used in a properly designed enclosure.
Fluoro-silicone should be used in applications that may come in contact with hydrocarbon based liquids, such as petroleum oils or fuels. The combination of a highly resilient and compressible material provide for positive
shielding and sealing performance, even under joint mismatch conditions of up to 0.032".
Gaskets can be easily die cut from sheet stock to conform to complex interfacing geometry.
PSA adhesive is available on sheet materials to aid installation.
Standard sheet stock is furnished in widths of 3", 4.5", 6" and 9" by 36" long. Sheet thickness from .020" and up, with tolerances of +/- .005". Custom sizes and configurations are available in molded lengths of up to 18 feet.
Vulcanized sections can be constructed in sizes to accommodate a wide range of applications. Standard strip part numbers and sizes are shown on the following pages.
