Silicones That Work

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 [...]

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 [...]

Specialty Silicone Products (SSP) is announcing that SSP-2551, a nickel-aluminum fluorosilicone that combines EMI shielding with fuel, solvent, and galvanic corrosion resistance, has been independently tested to 40 GHz and can be used with military electronic products that need to meet MIL-DTL-461 5.18 RE103 requirements for controlling electromagnetic interference (EMI). SSP’s EMI fluorosilicone has also been independently tested to MIL-DTL-83528 for elastomeric shielding gaskets and to [...]

Nickel-aluminum shielding silicones offer greater price stability than silver-filled materials for EMI gaskets. Silver prices increased 45.4% last year and silver investments during the first week of 2021 rose 90% compared to the first seven days of 2020. That’s bad news for industrial buyers, many of whom are now looking for alternative materials. Nickel-aluminum silicones can combine EMI shielding with other performance properties, but engineers need to see the test data before switching [...]

Specialty Silicone Products (SSP) makes conductive shielding elastomers with low levels of outgassing, the release of gases from a solid material such as silicone. Outgassing is a problem in high-vacuum environments such as outer space because released gases can condense upon and cloud sensitive devices such as camera lenses. SSP’s low-outgassing products meet ASTM E595 requirements for outgas testing and combine protection against electromagnetic interference (EMI) with environmental [...]
