We offer a wide range of different type of gaskets for your solutions. We can also produce custom profiles to your specifications.
Knitted wire mesh
Supplied on spools, coils or cut to length as individual gaskets with or without end seals. Standard profiles for a wide variety of applications are round, round with tail, double round with tail, half round (D) and rectangular.
We can provide most profiles as all mesh and all are available with an elastomer core to enhance compression characteristics and increase the deflection range. Standard wire materials are monel, TCS (tin plated copper clad steel), stainless steel and aluminum. Consult the factory for other materials. Wire selection should take into account attenuation potential, mechanical characteristics, and corrosion resistance.
The RoHS compliant metalized nylon fabric over polyurethane foam core gaskets are setting a new standard for EMI shielding control. Nickel-plating over a highly conductive copper plated substrate provides excellent electrical characteristics necessary for high attenuation shielding. Bonding the conductive substrate to the core assures self-termination when cut, while providing superior flexibility. All profiles have compression set of less than 3%.
Stick-on Mounting uses double-sided pressure sensitive transfer tape for a fast, reliable installation. 3M 9495LE non-conductive adhesive or equivalent. Apply only on a clean, oil-free surface and allow a 24-hour cure time.
Connectors and waveguide gaskets
Available in a variety of materials. The most common configurations are specified in the document for standard shell sizes. For other configurations a detailed drawing and specifications are required. These EMI shielding gaskets are available in conductive particles in elastomer Series 1000, oriented wire in elastomer Series 4000, monel foil in elastomer Series 5000 and aluminum mesh in elastomer Series 5500.
Finger Stock Gaskets
Tech-Etch’s RoHS compliant shielding strips are designed for a wide variety of application requirements. They are available in strips ranging from 16 to 24 inches in length, in continuous coils up to 35 feet long, as single fingers, or cut to requested full-finger lengths. Consult our engineering department for special modifications to suit your requirements.
Uncompressed heights of standard finger stock range from .03″ to .44″, which will occupy gaps as low as .01″. Many gaskets are offered in two material thicknesses to meet diverse application compression requirements: “Standard” and “TF”, which requires less force to compress the gasket to its operating range.
