Silver-Aluminum Fluorosilicone EMI Shielding Elastomer
SSP2486-70 (Type D)
MIL-DTL-83528 Type D Fluorosilicone for EMI/RFI Gaskets in Harsh, Fuel- and Solvent-Exposed Environments
SSP2486-70 is a 70-durometer, silver-plated aluminum filled conductive fluorosilicone elastomer designed to meet MIL-DTL-83528 Type D requirements. This QPL-listed material is commonly used as a CHO-SEAL® 1287 and CHO-SEAL® 1298 alternative for EMI/RFI gasketing in aerospace, defense, and other harsh-environment applications that require fuel, oil, solvent, and hydraulic-fluid resistance.
