Graphite Sheet - NESEAL Brand

NE o Graphite Sheets

There are many convincing reasons you should be choosing NE-o-GRAPH for your most demanding gasket applications.

  • 40% Compression
  • 20% Recovery
  • Less than 5% Creep relaxation

NEOGPG = NE-o-Graph Pure Graphite = Equivalent to 'B' Grade

NEOGFI = NE-o-Graph 604TC Foil Inserted = Equivalent to BSSC

NEOGTI = NE-o-Graph 298SS Tang Inserted = Equivalent to BTCS

Chemical Resistance:

Graphite is one of the most inert natural materials known. It will resist corrosive attack by a variety of chemicals, including many acids, bases, solvents, oils, and metals. (Exceptions: certain strong oxidizers, such as concentrated nitric or sulfuric acids, chloric acids, permanganates, chromium (VI) solutions, as well as molten alkali and alkaline earth metals.) For NE-o-GRAPH laminates, the laminating materials, ie. polyester, stainless steel, etc., may not be as resistant as the graphite alone.
