NeoGraf GRAFOIL® GTC Standard Internal Combustion Graphite, Single Layer Material
Categories: Carbon; Graphite

Material Notes: GRAFOIL® GTC flexible graphite sheet is a gasketing material containing no binders or fillers, which will seal a wide variety of liquids and gases over an extremely large temperature range. GTC can be used in a number of automotive or internal combustion applications. Additionally, GTC's ability to conform to less-than-ideally-finished surfaces is a benefit in aftermarket gasket applications. GTC is used in high-temperature sealing applications where binder-based materials fail. It is often combined with inserts to make head gaskets, exhaust manifold gaskets, EGR assemblies and filler material for heat shields. While maintaining an effective seal, GRAFOIL® material exhibits virtually no creep relaxation. As a result, the need for periodic bolt tightening is greatly reduced.

Formerly a product of GrafTech.
