Nickel-Graphite Fluorosilicone for EMI Shielding Gaskets
SSP-502F-80 is an 80-durometer fluorosilicone that’s filled with nickel-coated graphite particles. It’s electrically conductive and combines reliable environmental sealing with superior shielding against electromagnetic interference (EMI) and radio frequency interference (RFI). SSP-502F-60 is dark gray in color, has a thermal stability range of –55° C to 200° C, and provides fuel and solvent resistance.
EMI RFI Fluorosilicone with Silver-Like Conductivity
SSP-502F-80 is ideal for thinner, lighter-weight solutions and has a typical shielding effectiveness of 113 dB at 20 MHz to 10 GHz (E-Field). A full third-party test report is available. The shielding performance levels for SSP-502F-80 are comparable to silver-filled elastomers. Unlike silver-filled elastomers, however, this nickel-graphite fluorosilicone isn’t directly affected by fluctuating silver prices.
EMI Gasket Fabrication
SSP-502F-80 is supplied as in the following form factors:
- ready-to-mold compound
- fully-cured, conductive sheet stock
- extruded profiles
- continuous rolls
EMI gasket fabrication methods include compression molding and die cutting.
Comparing EMI Gasket Materials
EMI RFI silicones from Specialty Silicone Products have low minimum order quantities (MOQs) and short lead times. SSP sends certificates of analysis (COAs) that prove the quality of its materials and can also provide certificates of conformance (COC).
