High Thermal Conductivity Graphite Sheet Description: 1. Grafoil is Selected from the high purity natural flake graphite. 2. They are made through the advanced chemical treatment and mechanical procedure without fibers, binders or other additives. 3. It offer excellent sealing capabilities under extreme conditions with a longer life and less maintenance. High Thermal Conductivity Graphite Sheet Application: 1. Made for packing rings and various kinds of gaskets. 2. Cut into strip for filler of spiral wound gasket - Style TA440 3. Used widely in chemical, automotive and pump, valve industries. As a superior replacement for asbe-stos, new more applications are Being identified daily. 4. Temperature: -240~500C under oxidizing environment -240~3500C under non-oxidizing environment 5.
