Flexible Graphite Rolls/Sheet
DP1100Description
Flexible graphite sheets are manufactured from high purity natural flake graphite through chemical treatment, expanded under high temperature and then roll press into a roll. It has the characteristics of high-temperature resistance , corrosion resistance, anti-radiation, low creep relaxtion and good elasticity, and is the basic material for making all kinds of composite graphtie sheets, graphtie trapes, packing and gasket. Working temperature: -200~+650°C under oxidizing environment, -200~+3000°C under non-oxidizing environment.

Application
> Made for packing rings and various kinds of gaskets
> Cut into strip for filler of spiral wound gasket
> Used widely in chemical, automotive and pump, valve industries
Prime Features
> Lone life and less maintenance
> Replacement for asbestos, new more applications are being indentified daily.
