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 [...]
