Graphite Sheets
Graphite Sheets
ASSSEALS 4000 Pure Expanded graphite sheets & rolls (4000L) are 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:4000/N,4000L/N
 
APPLICATION :            Made for packing rings and various kinds of gaskets.
                                         Used widely in chemical, automotive and pump, valve industries.
                                         As a superior replacement for asbestos, new more applications are
                                         Being identified daily.
