The critical success factors for high quality graphite processing are: an homogeneous texture, a uniform grain structure, a perfect graphite impregnation process and consistent mechanical and thermal processing. Providing these, ensures that our products meet the most demanding requirements (including cGMP capabilities).
Graphite is characterised by its wide ranging and high level of corrosion resistance. It resists nearly all acids, solvents, chlorides and other halogen compounds as well as their corresponding alloys. Graphite’s thermal conductivity is much greater than most comparable corrosion resistant materials. A very low tendency to foul compliments and helps qualify the material for use in onerous applications.

Duties as extreme as quenching flue gas at 1,300°C can be accommodated with graphite as it is capable of withstanding wall temperatures within the range of -60°C to +200°C.
Diverse processes can be accommodated with the large available pressure envelope -1 bar to +16 bar .
Different raw material manufacturing processes provide for differing graphite grades, i.e. mechanical strengths, allowable operating temperatures and chemical resistance.
