Nickel-Aluminum vs. Silver-Aluminum for EMI Gaskets

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 [...]


Outgassing and Conductive Shielding Elastomers

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 [...]


EMI Sheets vs. Continuous Rolls: Manufacturing Costs and Considerations

Specialty Silicone Products (SSP) manufactures EMI gasket materials as molded sheets and continuous rolls. Buyers of EMI gaskets are more familiar with sheets, but there are some disadvantages to using EMI sheet materials. For example, EMI molded sheets are time-consuming to produce, may not offer the best material yields, and require new molds or modifications to existing molds to achieve custom dimensions. For oversized gaskets, molded EMI sheeting may require cutting and [...]


New Shielding Report and TDS for SSP Offsets to GORE® EMI Gasket Materials

Specialty Silicone Products (SSP) has published a new shielding effectiveness report and technical data sheets (TDS) for offsets to discontinued GORE® EMI gasket materials. Last year, W.L. Gore provided an end-of-life notification about two flame-resistant EMI shielding materials: GORE® GS2100 and GS5200. SSP is filling this gap in the marketplace by supplying quality alternatives backed by technical data, including UL V0 test summaries and the results of ASTM E595 outgas [...]


Did You Know SSP Makes EMI/RFI O-Rings?

Specialty Silicone Products (SSP) is manufacturing vulcanized and molded O-rings that provide shielding against electromagnetic interference (EMI) and radio frequency interference (RFI). The addition of our third extruder has allowed us to expand our bonded O-ring manufacturing and meet growing demand for reliable EMI/RFI O-rings made from the following shielding silicones:    SSP-502-65 nickel-graphite filled siliconeSSP-2368-65 MIL-DTL-83528 Type B siliconeSSP-2486-70 MIL-DTL-83528 [...]
