EMI Gasket Case Study: Appleton Marine

Appleton Marine designs and manufactures cranes, winches, windlasses, capstans, and custom designed equipment for commercial marine, offshore oil, and government applications. The Appleton, Wisconsin company also supports the U.S. Navy, which needs gaskets that combine reliable environmental resistance in marine environments with proven levels of shielding against electromagnetic interference (EMI). MIL-DTL-83528, a U.S. military specification, defines requirements for conductive shielding [...]


Die Cut EMI/RFI Gaskets for Military, Aerospace, and Communications

Die cut gaskets that are made of EMI/RFI silicones combine strong environmental resistance with proven levels of shielding against electromagnetic interference (EMI) and radio frequency (RFI) interference. As a gasket fabrication process, die cutting combines the advantages of speed and consistency with lower production costs and less material waste.Specialty Silicone Products (SSP) supplies EMI/RFI silicones and fluorosilicones for die cut gaskets as compression molded sheets and continuous [...]

Military and Aerospace Silicones: AMS, AA59588, MIL-DTL-25988

Specialty Silicone Products (SSP) makes military and aerospace silicones that meet AMS, AA59588 (formerly ZZR-765), and MIL-DTL-25988 (sometimes called out as MIL-R-25988 on prints, or as AMS 25988) requirements. These non-conductive materials are supplied as ready-to-mold compounds and compression-molded sheet stock for applications that include reinforced silicone seals for aircraft engines and fan blades. SSP’s aerospace and military silicones are also used in reinforced molded seals [...]


EMI Silicone Added to QPL for MIL-DTL-83528, Type K is Independently Tested

Specialty Silicone Products (SSP) is announcing that SSP-2571-85, an 85-durometer shielding silicone filled with silver-copper particles, has been added to the Defense Logistic Agency’s (DLA) Qualified Product List (QPL) for MIL-DTL-83528, Type K. This electrically-conductive silicone provides proven shielding against electromagnetic interference (EMI) and has also been independently tested for shielding effectiveness by DLS Electronics Systems, which also tested SSP-2571-85 for [...]
