Silver Plated Aluminum filled Fluorosilicones are the most commonly chosen conductive fluoroelastomers. Superior 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 meet or exceed all Military specifications known. Our 1157 is our Military compliant 70 durometer version useful in most high-reliability applications.
