Description:Grafoil is Selected from the high purity natural flake graphite. They are made through the advanced chemical treatment and mechanical procedure without fibers, binders or other additives. It offer excellent sealing capabilities under extreme conditions with a longer life and less maintenance.Nuclear Style grade:SINSTON ZR-NE20
APPLICATION:
Made for packing rings and various kinds of gaskets.
Cut into strip for filler of spiral wound gasket - Style SINSTON ZR5005
Used widely in chemical, automotive and pump, valve industries. As a superior replacement for asbestos, new more applications are Being identified daily.
Temperature: -240~500°C under oxidizing environment
-240~3500°C under non-oxidizing environment
