Parker Chomerics CHO-SEAL 1221 is a silver filled molded elastomer EMI shielding gasket in a fluorosilicone binder which offers excellent shielding but only fair corrosion performance.
Parker Chomerics CHO-SEAL® electrically conductive elastomer EMI shielding gaskets are available in sheet form, allowing for both design and manufacturing flexibility. Sheet materials can be die or water jet cut to make precision parts in large quantities.
