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 [...]

SSP 2020: The Year in Review

Specialty Silicone Products (SSP) is ending 2020 with a look back at the year via the content we provided. Recently, we announced the release of an updated EMI/RFI Silicones Catalog with an all-new Extrusions chapter and two bonus white papers. Earlier this year, we published an all-new white paper called “Bonded EMI O-Rings for Reduced Costs and Improved Performance” that you can download here.SSP’s Silicones That Work Blog announced both of these resources and contained [...]

REACH Compliance and Medical Silicones

Specialty Silicones Products (SSP) makes ultra-clean silicones that are used with medical devices and equipment. The base material in our SSP 2390-series elastomers meets USP Class VI requirements for biocompatibility. These platinum-cured silicones also meet FDA CFR 177.2600 requirements and comply with the European Union’s Restriction of Hazardous Substances (RoHS) Directive. Increasingly, however, we’re also asked about REACH compliance.The purpose of this article is to clarify [...]

EMI Conductive Silicones with Third-Party Test Data

How do you decide which EMI conductive silicones to specify and purchase? If you’re like most engineers, buyers, and product managers, you need to see third-party test data in order to trust a supplier’s products. Price, minimum order quantities (MOQs), and delivery times are important, of course, but there’s no substitute for independent testing, especially if you need EMI conductive silicones that meet standards like MIL-DTL-83528 for military gaskets or UL 94 V0 EMI gaskets [...]
