Silver Plated Aluminum filled Fluorosilicones are the most commonly chosen conductive fluoroelastomers. Excellent fuel and solvent resistance, combined with Extremely High Shielding Performance, light weight, excellent electrical conductivity, and the highest galvanic compatibility of all elastomers. The physical and electrical characteristics of our 115X Series meet or exceed all Military specifications known. Our 1155 is our medium durometer (50 +/- 7) version for low closure force / high conformance applications.
