NeoGraf GRAFOIL® GHH Standard Internal Combustion Laminate, Metal Reinforced
Categories:	Carbon; Graphite
Material Notes:	GRAFOIL® Grade GHH is a laminate made with GRAFOIL® Grade GTC flexible graphite chemically bonded to both faces of a flat, low-carbon steel core. Its applications include: exhaust sealing, gasoline/diesel head gaskets, EGR valve sealing, and turbo charger gaskets. While maintaining an effective seal, GRAFOIL® material exhibits virtually no creep relaxation. As a result, the need for periodic bolt tightening is greatly reduced. Laminate Construction: GRAFOIL® Grade GTC ? micro-thin, phenolic-based adhesive ? 0.004" thick Low-Carbon Steel Grade 1008 or 1010 ? micro-thin, phenolic-based adhesive ? GRAFOIL® Grade GTC Formerly a product of GrafTech.
