Flexible Graphite Sheet / Roll

General Features

Quality flake graphite has been chemically treated, expanded at high temperature, and rolled. It has excellent sealing properties, high temperature resistance, corrosion resistance, resistance to radiation, low creep relaxation rate, and excellent flexibility. It is the basic material for making graphite composite plates, graphite strips, fillers, and gaskets. Operating temperature: -196°C~600°C(in air), -196°C~3000°C(non-oxidized medium)
