Material Notes:

Conductive Fluorosilicone EMI/EMP Gasket. This material is silver-plated-aluminum-filled fluorosilicone elastomer which provides pressure and environmental sealing as well as high levels of EMI shielding. It is one of the more corrosion resistant silver-based elastomers, and is recommended where both salt spray and jet fuel environments are present.Molded and ExtrudedInformation provided by Chomerics
