Silicones That Work

Electronic designers need gaskets that resist electromagnetic interference (EMI), support electrical conductivity, and provide environmental sealing. In the automotive, aerospace, communications, and medical device industries, EMI gaskets made of particle-filled silicones are meeting these challenges. Yet designers also need elastomeric shielding with specific material properties such as softness or resistance to fuels. Cost-effectiveness and ease-of-fabrication are important, too. How to [...]

Particle-filled silicones provide environmental sealing, electrical conductivity, and resistance to electromagnetic interference (EMI) and/or radio frequency interference (RFI). These conductive shielding elastomers are filled with metal or metal-coated particles, and are supplied as sheets, rolls, or ready-to-mold compounds for the cost-effective fabrication of silicone shielding gaskets. Engineers use particle-filled silicones in numerous shielding and sealing applications, but can these [...]

Defense contractors need military gaskets that conduct electricity, resist electromagnetic interference (EMI) or radio frequency interference (RFI), and provide environmental sealing. Particle-filled silicones can meet project requirements, and also comply with MIL-DTL-83528, a U.S. military specification (MIL-SPEC) for electrically-conductive elastomeric shielding gaskets used in EMI and RFI suppression. MIL-DTL-83528 Gasket Materials As part of its line of SPECSHIELD™ EMI RFI [...]

Medical device and medical equipment manufacturers need high-purity silicones for tubing, cables, seals, gaskets, and other components. Specialty Silicone Products (SSP) supplies an ultra-clean line of platinum-cured silicones that are FDA, USP Class VI, and RoHS compliant. SSP-2390 Series silicones are also cost-effective and come in a range of durometers and custom colors. These medical grade silicones support precision die cutting and extrusion, and are available as sheets and ready-to-mold [...]

Gasket fabricators who supply defense contractors need to source products that meet military requirements. The U.S. Department of Defense (DoD) Product Qualification Program (QPL) lists materials that meet military specifications such as MIL-DTL-83528 for electrically-conductive elastomeric shielding gaskets. Particle-filled compounds in QPL 83528 are qualified by the Defense Supply Center Columbus (DSCC) Qualifications and Sourcing Unit (VQ), part of Defense Logistics Agency (DLA) Land and [...]
