TERMOGRAF FGF Purified natural graphite is treated with acid at high pressure. It is heat and chemical resistant and has excellent flexibility and elasticity so various jigs can be processed again even without any additive or adhesive.TERMOGRAF FGF Flexible Graphite maintains the utmost in performance and sealability. Available in rolls, sheets, and cut or otherwise formed to fit virtually any configuration in most any application requiring a durable, low maintenance, high performance gasket.APPLICATIONSTERMOGRAF FGF flexible graphite is an extremely versatile sealing material made without binders, resins or other additives; it is the obvious choice for such internal combustion applications as:
- Exhaust manifold gaskets
- Exhaust ring seals
- Turbo charger gaskets
- Intake manifold and crossover gaskets
- Gas turbine seals and gaskets
- Heat shields
- Airbags
Noise and vibration harshness (NVH)
TERMOGRAF FGF GRAPHITE FOIL GRADES
TERMOGRAF FGF is made from flake graphite with high carbon content which is gone through chemical treatment, expanding under high temperature and then rolling.It has the characteristics of high temperature resistance, corrosion resistance and good elasticity, and is the basic material for making all kinds of reinforced graphite sheets, graphite tapes, packing and sealing gaskets. Working temperature-200~650oC(in air),-200~3000oC(in non-oxidizing media).
TERMOGRAF has four grade scope for its graphite foils in roll.
Grade N is Nuclear grade graphite foil, it can be used to make gaskets to use in nuclear power plant.
Grade A is the best materials to use in common industry, which usually are used to make cylinder head gasket, graphite sheet gasket, spiral wound gasket etc.
Grade B is the better materials to use in common industry, which usually are used to make spiral wound gasket, manifold gasket, graphite sheet gasket, graphite rings and packing yarns.
Grade C is the common materials for industry usage.
