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 [...]


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 [...]


EMI Shielding for eVTOL Aircraft

Electric vertical takeoff and landing (eVTOL) aircraft need reliable shielding against electromagnetic interference (EMI) and dependable environmental sealing. Although the brushless DC motors that are used with eVTOL aircraft do not generate significant amounts of EMI, these motors are not altogether free from electronic noise. Moreover, because eVTOL development is coincident with 5G, eVTOL aircraft are expected to use densely-packed circuits that are susceptible to cross-talk and that [...]


EMI/RFI O-Rings for Military Connectors

EMI/RFI O-rings for military connectors are donut-shaped gaskets that combine reliable environmental sealing with proven levels of shielding against electromagnetic interference (EMI) and radio frequency interference (RFI). They are not the same as flat, washer-style EMI gaskets. Rather, EMI/RFI O-rings are designed for tough environments where temperature, pressure, and tolerances could cause other types of EMI gaskets to fail.Military Connectors and Gasket Compression SetWith military [...]


EMI Shielding for Electric Vehicles: Get the White Paper

Electric vehicles (EVs) are susceptible to electromagnetic interference (EMI) because they put significant amounts of electrical and electronic content into confined spaces. The radiated and conductive emissions from these systems can disrupt circuits and result in conditions that range from minor inconveniences to dangerous losses of vehicle function. Without proper EMI shielding, performance and safety can suffer.In a new white paper, Specialty Silicone Products (SSP) explains what engineers [...]
