Flexible graphite roll ,also name expended graphite sheet ,it is made from expanded graphite .
Flexible Graphite roll,also name "Expanded Graphite Sheet", it is made from high quality and purity flake graphite, which is gone through chemical treatment, expanding under high temperature and then rolling. It is a basic material for making different kinds of graphite sealing products.
We also supplier Nuclear grade Flexible graphite roll.
Typical Application
1.Made for died form packing rings and reinforce graphite gaskets
2.Cut for tape or strip, which is filler of spiral wound gasket
3.Used widely in chemical, automotive and pump, valve industries
