| Expanded Graphite
Sheet & Roll are selected from the high purity natural
flake graphite.They are made through the advanced chemical
treatment and mechanical procedure etc.This products inhance
excellent properties such as thermal stable,with stand high
and low temperature,corrosion,resistance.It has been widely
used for die formed packing rings and various kinds of gaskets.It
is a basic material for making different kinds of graphi te
seals.Special specifications can be ordered on customer's
demands. |
