Specialty Silicone Products (SSP) supplies EMI conductive elastomer extrusions in the shapes, sizes, and shielding silicones that engineers, material converters, and gasket fabricators need. SSP’s major investment in a 40-ton Loomis extruder complements our in-house tooling and bonding capabilities. For shorter lead times, lower costs, and bonded gaskets, choose EMI extrusions from SSP.  Let’s take a look at what you need to know to get started.  Profile Shapes and [...]


New Flame-Retardant Shielding Silicone Meets UL 94 V-0

Specialty Silicone Products (SSP) now offers a 60-durometer, nickel-graphite shielding silicone that meets the flammability requirements of UL 94 V-0, a flame-testing standard from Underwriters Laboratories (UL). Flame-retardant SSP-502-60-V0 is supplied as a ready-to-mold compound, fully-cured conductive sheet stock, or as continuous rolls. This particle-filled silicone supports gasket fabrication through a variety of manufacturing methods and provides environmental sealing and electrical [...]


What’s the Best Way to Bond EMI O-Rings?

EMI O-rings combine environmental sealing with protection against electromagnetic interference (EMI). They’re made of silicone compounds that are filled with metal or metal-coated particles such as silver, silver-aluminum, or nickel-graphite. Gasket fabricators produce EMI O-rings by cutting EMI cord stock and then bonding the ends of cut lengths together. Applications for these donut-shaped seals include automotive, aerospace, industrial, medical, and military electronics. To convert EMI [...]


New White Paper: 3B Certified Silicones with High Flex-Fatigue Resistance

Specialty Silicone Products (SSP) is announcing the release of a new white paper that describes the company’s 3B certified silicones with high flex-fatigue resistance. The Ballston Spa, New York (USA) manufacturer supplies military and aerospace silicones that meet the full requirements of the A-A-59588 3B specification – with no exceptions for flexural testing.  Other suppliers claim that their silicones meet the A-A-59588 3B standard, but these materials only meet its [...]


Bonded O-Rings for EMI Shielding

Specialty Silicone Products (SSP) extrudes EMI elastomers into solid cords that come in various stock sizes. Die cutters and other gasket fabricators can convert these cords into bonded O-rings that provide EMI shielding and environmental sealing. To join the ends of cords together, fabricators can use either cold bonding or vulcanization. Each method has advantages and disadvantages, so it’s important to select the technique that best suits your requirements. Here’s what you need to [...]
