EMI Shielding Gaskets for Military Electronics

emi shielding gasketsEMI shielding gaskets for military electronics are used in everything from touchscreens to targeting systems. To prevent electromagnetic interference (EMI) from disrupting electronic equipment, Elasto Proxy custom-fabricates EMI shielding gaskets from particle-filled silicones. These specialized materials combine the materials properties of silicone rubber with the electrical properties of metal. Elasto Proxy uses waterjet cutting to convert shielding silicones, and bonds cut lengths with conductive adhesives.

EMI gaskets from Elasto Proxy meet the requirements of MIL-DTL-83528, a U.S. Defense Logistics Agency (DLA) specification for electrically-conductive elastomeric shielding gaskets. MIL-DTL-83528 establishes minimum shielding effectiveness levels for various material types over a frequency range of 20 MHz to 10 GHz. MIL-DTL-83528 also specifies hardness or durometer (Shore A) measurements for shielding silicones that are categorized as low, medium, or high durometer. (more…)

Electronic Devices and EMI Gaskets

EMI GasketsEMI gaskets help to protect electronic devices and equipment against disruptions and disturbances caused by electromagnetic interference (EMI). Because these shielding gaskets are made of particle-filled silicones, they also provide environmental sealing and resist a wide range of service temperatures. Depending on the durometer, the base elastomer supports varying degrees of compression. The metal or metal-coated particles provide EMI shielding and electrical conductivity.

Elasto Proxy custom-fabricates EMI gaskets for medical, military, mass transit, and many other applications, including aerospace. With our water jet cutting capabilities, we supply low-to-medium volume quantities of custom EMI gaskets with no tooling costs. In addition to flat connector gaskets, we manufacture EMI shielding gaskets from extruded materials. Water jet cutting isn’t just cost-effective. It’s also fast and precise, making it a great choice for prototypes. (more…)

Thin EMI Gaskets

EMI GasketsElasto Proxy custom-fabricates EMI gaskets from nickel-graphite filled silicones that contain an inner layer of conductive fabric for added strength and thinner designs.

Some electronic designs need EMI gaskets that balance physical strength with support for thinner devices. Conductive elastomeric shielding gaskets are a proven technology, but some design engineers worry that shielding silicones are packed with so many particles that these elastomers are brittle and will tear easily. Other engineers believe that particle-filled shielding elastomers are too thick, and can’t support electronic products with thinner profiles. These concerns are important ones, but Elasto Proxy can address them by fabricating EMI gaskets from nickel-graphite shielding silicones that are reinforced with conductive fabric. (more…)

Rubber Sheets for Flooring, Sealing, EMI Shielding, and Insulation

Rubber sheets aren’t only used for flooring. They’re also used for environmental sealing, EMI shielding, and sandwich-style insulation against heat, noise, and vibration. Choose standard sheet stock or specialty sheeting, and ask Elasto Proxy to use water jet cutting and laminating or adhesives to create your custom solution.

Rubber sheets are used for sealing and insulation in industrial, commercial, and military applications. Many different types of rubber sheet stock are available, but an off-the-shelf product may not be right for your application. By working with a custom fabrication specialist, industrial buyers and designer engineers can source standard or specialty elastomers and then have rubber sheeting cut to size. Elastomeric sheets with laminates or adhesives already applied can also speed sheet installation. (more…)
