Nickel Aluminum EMI Gasket Materials
Compare nickel aluminum EMI gasket materials to silver aluminum silicones and fluorosilicones for EMI shielding. 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 […]
MIL-DTL-461 Fluorosilicone Meets EMI Requirements
SSP’s MIL-DTL-461 fluorosilicone meets tough EMI shielding requirements and combines fuel and solvent resistance with low outgassing. Specialty Silicone Products (SSP) is announcing that SSP-2551, a nickel-aluminum fluorosilicone that combines EMI shielding with fuel, solvent, and galvanic corrosion resistance, has been independently tested to 40 GHz and can be used with military electronic products that […]
5G EMI Gaskets for Telecommunications
5G EMI gaskets for telecommunications can use SSP2551, a nickel-aluminum EMI shielding fluorosilicone with strong environmental resistance. 5G telecommunications gaskets need reliable EMI shielding for electronic enclosure seams, power and signal panels, and connector backshells. As 5G networks proliferate, the isolation of sensitive circuits and electronic systems is becoming increasingly important, especially in urban environments. […]
ASTM E595 EMI Silicones are Low Outgassing
SSP makes ASTM E595 EMI silicones that are low outgassing. The ASTM E 595 standard was developed originally by NASA. Specialty Silicone Products (SSP) makes low outgassing silicones and publishes the ASTM E595 test data that we receive from independent laboratories. All third-party test reports are available on SSP’s website so that you can view […]
EMI O Ring Applications and SSP’s Advantages
EMI O ring applications solve the continuity issues in removable parts in an enclosure. They also seal gaps and improve enclosure reliability. Electromagnetic interference (EMI) occurs when external electromagnetic energy mixes with another electronic system and then disturbs the system’s original flow. EMI is one of the identified causes of the decrease in performance or, […]
MIL-DTL-25988 Fluorosilciones with Full COAs and Low MOQs
MIL-DTL-25988 fluorosilciones from SSP are available with certificates of analysis (COA) and low minimum order quantities (MOQs). Specialty Silicone Products (SSP) makes MIL-DTL-25988 fluorosilicones with a full certificate of analysis (COA) for each batch and with no extra testing fees or costs. Plus, SSP supplies these military and aerospace silicones in sheets, rolls, and ready-to-mold compounds with […]
Bonded EMI O-Rings Reduce Costs and Improve Performance
Specialty Silicone Products (SSP) makes bonded EMI O-rings that provide shielding against electromagnetic interference (EMI), electrical conductivity, and environmental sealing. At our manufacturing facility in Ballston Spa, New York (USA), we extrude cords of shielding silicones, cut them to size, and then bond O-rings using a proven process with multiple quality control checkpoints. These products […]
Supplier Value and the Silicone Shortage
The continuing shortage of silicone rubber is forcing suppliers to have some challenging conversations with their customers. Whether it’s because of price, lead times, or a need to limit purchases, buyers are understandably concerned. Unfortunately, there aren’t any quick fixes. Today’s silicone shortage is expected to last for at least six months, and that’s without any additional […]
Military Connectors Use Conductive O-Rings
Military connectors need conductive O-rings that provide reliable levels of EMI shielding and resist compression set. EMI/RFI O-rings for military connectors are donut-shaped gaskets that combine reliable environmental sealing with proven levels of shielding against electromagnetic interference (EMI) and radio frequency interference (RFI). They are not the same as flat, washer-style EMI gaskets. Rather, EMI/RFI O-rings are […]
MIL-DTL-83528 Type A EMI Fluorosilicone Added to QPL-83528
SSP’s MIL-DTL-83528 Type A EMI fluorosilcone has been added to QPL 83528. Specialty Silicone Products (SSP) is announcing that SSP-2569-65, an EMI silicone filled with silver-copper particles, is now part of the Qualified Product List (QPL) for MIL-DTL-83528, Type A. In a July 22, 2021, letter, the Defense Logistics Agency (DLA) informed us that SSP-2569-65, a […]
